Best Lithium RV Battery

There are many reasons you should think thoroughly about choosing what type of cell your home trailer needs. Selecting a cell should depend on how you plan to use your vehicle and how long you are planning to live in it. 

If you are a heavy boondocking camper or love going off the grid for an extended period, you need a cell that can last for a few years of use. Not only that, but home trailers could also have a lot of electrical devices and power-hungry electronics connected to it. 

Therefore, it needs to have a healthy cell that can deliver the amperage necessary to start the home trailer and current on its electrical factor. 

Li batteries can deliver up to 2,000 rounds. It means your cell can endure up to two decades if you go boondocking and load your cell as frequently as 100 rounds in a year! 

In this product review, you’re to read some types of batteries that are gaining popularity for modern home trailers. There are many types of batteries, but we will be focusing on LA (lead-acid) and lithium batteries. LA is a compound of sulfuric acid and lead plates. 

This type of cell was the first rechargeable cell they developed in the late 1850s. On the other hand, lithium batteries are much more of a modern design that has been commercially available since the 1980s. 

Li technology has become well-established and recognized for energizing small gadgets like computers, mobile cells, and other cordless power tools to more extensive cell-driven usage like cars and home trailers and can sustain off-grid lifestyles.

Our 10 Best Lithium Battery for RV Reviews 2020

Apart from the LifePO4 being the editor’s choice, we listed some powerful cells that you can use for your home trailer should it suit your RV’s needs better than BattleBorn LiFePO4 DC Battery. 

We based our top pick in terms of consumers’ positive surveys and the cell’s overall make up. This cell generates the most satisfying reports when it comes to durability, life span, and practicality.

1. Battle Born LiFePO4 Deep Cycle Battery


  • More number of charge rounds
  • wider operating temperatures range
  • constant voltage during the unload rounds
  • Easy future expansion if you want to add more later.
  • Can last up to a decade
  • Can be wired in series or parallel
  • Maintenance-free
  • Compact and lightweight
  • safer
  • With temperature and voltage safety
  • Can be installed indoors

Lithium batteries have been leveling up the cell game for decades, and when you hear about this cell, you can think of many other great advantages. It is safer and can last up to decades, with its multiple charge cycles, lightweight, and compact size.

It is essential to understand the kind of cell you are buying to help you seize the most excellent RV battery. LifePO4 has 4-5x the number of charge cycles. It is equipped with short-circuit security for safety and has a broader operating temperature range, even compared to its own kind, the Ionic Li with an actual voltage of 12.8, and constant voltage throughout the discharge cycle, as seen in the graph.

In the graph above, by comparing the two Lithium batteries in the market, Li iron, and ionic Li, we discharged them up at the same amount of current. To show you significant differences between the two (as according to the graph), it presents a discharge diagram of a LifePO4 10Ah cell fired up at a 3amp current vs. notable 10Ah Li-i (lithium-ion) fired at a 3amp current flow.

It is noticeable how the LifePO4 conveys a steady voltage through the RV battery life cycle vs. the continuous decrease of current on Lithium-i.

Now, both batteries are excellent in their own compound. Here, we want to show you the difference between the two high performing cells that suit your use. We picked LifePO4 because having a cell carry on for a decade and would weigh only 29 pounds are healthy choices for your rig. 

This means you don’t have to change my cell every three years as I did with the sealed LA I was using. Besides, it has all the excellent assessments from home trailer owners.

Though it is quite costly compared to the rest of its kind, I wouldn’t mind paying a few hundred bucks for its regular price if it means more lifespan added to the cell life. It will be worry-free for you during the winter, where you would not have to change it, should it die down while you are off the grid.

Premium Pick

The cell is an essential part of every laid framework of home trailers. If you love boondocking and driving off the grid for an extended period, you need a reliable 12-volt Li-i home trailer cell to aid you in supplying all the current required for your appliances. 

If this is the case, then you need the one made by VoltXcell. I am quite impressed with this particular cell. Opposite to LA  cells, the chemical structure of Li -Iron-Phosphate or LifePO4 significantly increases the unload and reload rate. 

In terms of versatility, VoltXcell Volt LifePo4 100ah Li batteries are for mobile homes. This unit can actually store sun or wind load. This cell is highly efficient in collecting current if you have a solar panel built up in your home trailer. 

This means that you do not need to buy a separate cell to store this renewable current. What you might find not in your liking about this cell are the size and the weight. It is remarkably huge, and lifting it would be very difficult, especially for those who have mobility issues. On a positive note, it does not overheat.

5. Shunbin 12V Lithium-I Battery


  • Comes with its own bundle of fast charger
  • Fast-charging
  • Also available in 100, 200, or 300V
  • Has a cell control system that guards the cell so it could carry on longer
  • Fitting for automotive or heavy-duty equipment
  • Can endure high or low  temperatures (both discharge and storage temperatures
  • Comes with a 3-year warranty


  • No built-in handles
  • Has an old-design design
  • Very heavy

You might have been using LA  mobile home accumulators before and heard many satisfying things about Li-i cells for mobile homes. The tricky part is what to pick between the available choices, so I finally decided to buy this Shunbin 400Ah 12V cell. 

As I have said, I was using a LA  type cell before and decided to use a LifePO4 system due to its life duty and size. Upon receiving this Shunbin cell, you will be amazed that it loads faster than my old AGM, and that is a huge plus point for me. 

When it comes to the warranty period, this 12-volt Li RV cell comes with a 3-year warranty, whereas others only warranted for a year. Upon citing that this cell may not come cheap at all, but judging that it has a built-in BMS to help you interpret what’s happening inside the cell with a 400Ah cell, you will only need one of these in your system, thus minimizing your cost. 

Using multiple types of these accumulators to make your work system will save you cash and some space in your home trailer that will take off some loads in your rig. The only drawback of this cell is that it looks so outdated, and at several pounds, it is not easy to move around, though the casing style made it extremely durable.

6. Orient Power 12V 100Ah LiFePO4 Battery


  • Can carry on for more than 8,000 rounds
  • Fast-charging
  • Compact and lightweight which makes it fitting for small electric vehicles, like e-bikes or boats                               
  • Customizable
  • Excellent disload profile
  • Easy to scale up and extend a solar current system
  • Performance-tested before shipping
  • Can endure high amperage


  • The packaging does not look sturdy
  • Does not have any display or monitor that allows you to detect the cell’s performance

If you are running a solar system, then  Orient Power 12V 100Ah LiFePO4 Battery will be just a fantastic choice for you to back you up in seasons of rare sunlight. This cell is excellent for any usage, especially Solar.

If you are using sealed LA  cells cannot handle high amperage and would not load well with your setup, making it hard for your system to work on cloudy days or not work at all, this cell can particularly help you to solve that problem.

Two assemblages of this cell will make your home trailer a source of endless current for a more extended period. These LifePO4 cells load notably effortlessly. There is little internal resistance making it consume a ton of amps before the voltage rises. 

It means that even though it is a cloudy day, you can gather 100% of the module manufacturing even for brief intervals. An L-acid cell does NOT accept high amperage, as cited above. This means it will resist more and turn more current to heat as it goes the full load.

If you own a LA  cell, then you’d probably know that your LA  bank may only accept 20a as it becomes fully charged; this cell, however, will absorb the full 80a until it is almost completely loaded.

7. RUIXU LiFePO4 Lithium Iron Phosphate Battery Pack


  • High quality new Sinopoly prismatic cells

  • It has significantly lighter weight than the comparably sized L-acid  cell used in the automotive and marine industry.


  • There is no informative label on the cell

Although Li could be the beast of all cell types, not all of them are built equal. Unfortunately, some of them can only live half of life; that depends on how you take care of it. The excellent news is, this Go power GreenLiFE Battery GL100 12V Li-i cell can perform what it promises in a way that you will get your investment’s worth. 

There are just so many things to love about this cell. In terms of external design, it is pleasing to the eyes. The cells are even bound together and made of a substantial development for better adherence, conductivity, and strength. This cell can be installed and manipulated in any way—no liquid to spill—furthermore, the GreenLiFE Battery GL100 12V Li-i cell self-unloads less than 3% per month. 

It can hold a full for over a year and has practically no self-unload. Lead cells lose up to 30% of their capacity per month due to self-unload.

It is also worthy to note that the manufacturer placed a security system that could prevent your electronic gadgets and other appliances from being damaged. 

And that feature is rare on other related products in the market these days. If you are used to having small cells, then you might find that this product is quite bulky for your tolerance.

A surprising fact about this cell is that it is built with 3.2V 5AH tubular Li-i Cells. Each cell is devised with a shockwave-proof stainless steel case, flame retardant electrolyte, and a built-in thermal igniter.

9. Ionic Lithium Deep Cycle Battery 12V50-EP

The 12V 50ah cell is excellent for trolling motors to linger on the water all day and has the most satisfying feedback. Not only that, but you can also examine your cell performance with the Bluetooth App. It also has safety features like a built-in microprocessor regulated cell management system (BMS) that interpret the key working parameters during charging and discharging, such as voltages, currents, and internal temperatures.

This cell is highly commendable if you are using a DC system.  Ionic DC  cells can be secured up 4 in series and as many needed in parallel. The typical size of this cell compact is lightweight, easily fits, operates a motor, but doesn’t carry on long before it needs recharging. Also, the blue-tooth monitoring purpose will not work. There is no guide manual included, and when trying to access the Bluetooth signal, a message appears saying, the password does not match; without asking for a password. So it doesn’t have a friendly-user Bluetooth system. The cell loads very quickly, though.

Another excellent Ionic cell with Li-Iron Phosphate (LiFePO4) chemical structure is this 12 Volt 100Ah Li DC Battery. This cell quickly works by plugging it and playing with starting or DC  systems, including a home trailer, Electric cart, Propulsion, Solar, Off-Grid, Marine, and other usage demanding a lightweight Lithium-ion to substitute LA, Gel or this type of cells.

This 12V 100AH Li-i cell is an excellent replacement from a group 31 AGM, LA  cell, or GEL. Designed as a “drop-in replacement,” implying that all you need to do is take out your previous group 31 cell and assemble the Lithium cell in the same way.

The entire package is extremely solid and expertly completed compared to other lithium batteries you have probably bought. This cell looks the part of a first-rate quality product that is a super lightweight and potent DC cell alternative to the LA  equivalent product that can cost $2-300 and weigh as much as 80lbs 10hrs to load.

Types of RV Batteries

Many self-help books, blogs, and analysis can give you pretty much ideas on different types of RV Batteries or what to look for in a cell that could suit your need for your RV. Here, we will give a brief run down to three types of cells that modern home trailers are using right now.

  •  LA Batteries

AGM (Absorbed Glass Mat) has made the flooded batteries obsolete. The flooded cell is the type of RV battery ll that requires the owner to add water frequently. If you care about how to extend the life of an RV battery like this type of accumulator, you need to learn a thing or two about the basic knowledge of how it works to maintain it.

Some cells used in RV are LA batteries. LA has several cells connected to a series. Each of the cells generates roughly 2.1 volts. So a 12-volt cell with six cells in a series yields an output voltage of 12.6 volts. LA batteries are made of lead, plates, and lead oxide immersed in the electrolyte, which is 64 percent water, and 36% sulfuric acid.  

The amount of the electrolyte and the size of the lead plates are determinants of the amount of charge a LA cell can store. This being said, LA cells do not make electricity, but instead, they save electricity.

This type of cell has been successful for so many decades with its excellent track record. This type of accumulator can be more costly than the flooded type, but considering the variety of accumulator benefits, it is worth the cost. This type of cell is still LA-based cells but sealed instead of vented. 

You don’t need to worry if it’s going to leak when you transport it because the electrolyte is kept confined in a fibrous glass mat that can’t be spilled. So shipping it is smooth without any hazardous chemical constraints. 

Also, this glass mat comes with pockets that aid in the recombination of oxygen and hydrogen gasses (which are generated throughout charging) back into the water.

This type of accumulator having thick positive plates belongs to the True DC class. The reason it does not need to be watered is that they do not outgas; thus, they do not damage terminals. In this way, it will save you a significant amount from the maintenance cost. Just avoid severely overcharging this type of accumulator.

  •  Deep Cycle

A DC cell is manufactured to provide current for a very long period, even until it reaches 80% discharged and more at which point it needs to be recharged. But if you want to extend the life of the cell, do not discharge it below 45%. 

This type of cell is usually used in RV to power electronics and appliances, using the stored charge from the sun panels. Compared to this type of accumulator, DC has few thick plates.

 The purpose of this is to use a small amount of current for a more extended period and to require a gradual to an average amount of recharge rate. 

It is clear now that this RV cell applies mostly in “domestic” use because it can endure 700 to 800 DC and more depending on the type and size before you can replace them. 

Take, for example, a golf cart with a 6-volt cell; this is a real DC type. 

It is important to note that not all labeled “DC” are True Deep Cycle cells. This type of cell is available in flooded and this type of accumulator.

  • Lithium Batteries

Now, we move on to the Li cell type. These are the leading home trailer batteries now in the market. Although it costs more than this type of accumulator, it is worth the cost for its longer lifespan. If well-maintained, you can expect to have about 2500 to 5000 rounds. And to add another value, a laboratory test shows that a Li cell will deliver more than 75% of its potential after 2500 rounds. 

The cycle base is another thing to consider about your Li cell. The base rounds refer to the load consumed before it is to be refilled. Fundamentally speaking, it concludes how much percentage of its load should be utilized before recharging it again.

 This matter paints a bigger picture because, as cited earlier, the life of a Li cell is determined by how many rounds it can make. 

So this only means that the less it needs to do full rounds, the slower it ages. And for this very reason, a DC Li RV accumulator is the leading cell for boondocking.

A valuable advantage of Lithium batteries is that there is no sagging when it comes to loading level, unlike in LA cells where the load level decreases, and so does its voltage. If this happens, your appliances or any electronics running inside your home trailer will start to run haphazardly.

Lithium battery, however, the discharge arc is noticeably steady (as shown in the graph above), this means the Li cell at a certain percentage will produce nearly the same amount of voltage as it would at 80%. 

On the course that the lithium battery has fully discharged, the load will drop immediately, damaging the cell permanently. It is the job of the Battery Management System (BMS) to read the working of the cell to avoid this from happening.

Any generator auto-start or any mobile home batteries monitor that is dependent upon detecting the sagging of voltage levels will likely not be on a Li bank. A shunt based calibrated monitoring system will be the most efficient way to catch the load level of a Li cell bank.

Frequently Ask Questions

Which Is Better: AGM vs Lithium

Some typical campers and boondockers are still using this type of accumulator because, yes, we can say it works, and it is way less costly than that of the Li Iron Phosphate. On this note, we listed the comparison between the two on some technical features and capacity.











Common type : 20.5″ x 10.5″ x 9.5″

Takes up much space


Requires temperature control below freezing point

No problem with any temperature levels 





100Ah (amp hours) = 80Ah-90Ah (or unload to 80%-90%) 

AGM’s 50Ah (or reload of 50%) before needing to reload


costly/ can carry on up to a decade

Less costly/can carry on up to half a decade




Useable Energy and Cost

It is commonly accepted that the most cost-effective and reasonable base of unloading (DOD) for this type of cell is 50%. For Li -iron-phosphate (LiFePO4 or LFP), which is the most stable of the mainstream Li-i cell types, 80% DOD is used.

To get 300 usable amp-hours capacity with this type of accumulator and have a reasonable life expectancy requires us to use 600 amp-hours of cells. It is widely known that the life expectancy of this type of accumulator severely drops off when unloading more than 50%. 

Let’s take two Victron 24V cell models and analyze useable current for a small yacht:

  • 1 x Victron Li-i 24 V 180 Ah

The given voltage of the LFP cell is 3.3 V. This 26.4 V LFP cell consists of 8 cells attached in series with a 180 Ah rating. The usable current is 26.4 x 180 = 4. 75 kWh. Useable current is 26.4 x 180 x 0.80 = 3.8 kWh.

  • 2 x Victron AGM 12 V 220 Ah

The given load of the L-acid cell is 2.0 V/cell. Each 12 V monobloc cell is composed of 6 cells connected in series with a 220 Ah rating. Combining 2 x 12 V 220 Ah cells in series to give 24V and 220 Ah, the usable current is 24.0 x 220 = 5.28 kWh. Useable current is 24 x 220 x 0.50 = 2.64 kWh.

This equation begs the question: What is the Ah rating of this type of accumulator that would be equivalent to the 3.8 kWh usable current of the Li-i cell? To get 3.8 kWh of usable current from this type of accumulator, it would need to be double the size to start with due to the 50% DOD market rule, i.e., 3.8 x 2 = 7.6 kWh.

 At 24V, that would suggest 7,600/24, which gives us a cell assessment of 316.66 Ah, which moves closer to twice the rated potential of the Li-i 24 V 180 Ah. This does not mean, the aging of the cells, temperature derating, or higher loads for this type of batteries; higher loads have a more significant effect than on Lithium batteries. 

With all this data, it is reasonable to say that this type of accumulator will need to be double the Ah rating of a Li. What about the cost? Using the Victron cost list, we see that a 12V 220 Ah AGM is € 470 ex VAT or 2.136 €/ Ah. 

For 316.66 Ah, that is equivalent to € 676.50 at 12V or € 1,353 at 24 V. The 24V 180 Ah Li is € 4,704 for the same volume of usable current. Therefore, it is 4,704/1,353 = 3.48 times more costly (or less if we examine the part of 2 referred to above) when analyzing Ah ratings.

Based on this, you might conclude that Li is not cost-effective; however, usable current compared to the cost is only a part of a bigger picture.

Weight and Size

Since Lithium batteries do not contain the dense LA found in this type of accumulators, it makes it lighter. Given that their DOD (depth of charge) is 80 to 90%, its cell bank only occupies less space. Because of this reason, lithium batteries consume less weight and volume compared to this type of old accumulator.

Most Ah grades of cells, despite the type, are stipulated at a 20-hour rate. This was acceptable in the old days of light loads, but as the number of parts and the size of loads has increased over a while, we also need to look at high short term loads, medium, and longer-terms for different varieties of equipment. 

This might mean a considerable cell package. With a large package, as shown below, it becomes clear just how heavy LA compared to Li. 1360/336 it is four times heavier.


While lithium battery have been making noise in the market due to its many advantages. It’s been long since this type of accumulator has proven its technology. It is common knowledge that this type of accumulator can be loaded in freezing temperature, unlike Li, where you need to regulate the temperature to be able to load it in the extreme climate, such as below-freezing point.


Both Li and AGM cells are sealed; they are deemed maintenance free.

Charge Efficiency

First, let’s analyze the load efficiency of LA on the left to Li on the right, during the entire load round. Loading the carry on 20% of a LA technology cell is always slow and ineffective compared to Li. 

This is carried out in the fuel costs (or any charging source you use) in the pictures further down. Note the changes in load numbers too.

The suggested load rate for a considerable size of this type of battery is 0.2C, i.e., 120A for a 600A cell consisting of equaled 200Ah blocks. More above load rates will heat the battery (temperature coverage, voltage sensing, and proper airing are required in such cases to block thermal runaway).

Due to innate immunity, the immersion voltage will be attained when the cell is energized at only 60% or less, ending in a more extended immersion needed to load the cell fully.

Higher efficiency means a faster rate of load for lithium batteries. They can handle a higher amperage from the load; thus, they can be refilled much faster than LA.

We represent the load rate as a piece, such as C/5, where C = the cell capacity in amp-hours (Ah). 

So that means a 430 Ah cell charging at a speed of C/5 would sustain 86 charging amps (430/5).

LA cells are restricted in how much load current they can handle, primarily because they will overheat if you load them too hastily. 

Besides, the load rate gets significantly slower as you near full capacity.

LA cells can load around C/5 throughout the bulk phase (up to 85% potential). Then, the cell load automatically relaxes down to top off the cells. 

This means the load rate in LA is prolonged, now and then, more than twice as long as a Li alternative.

Battery Choices, markets, and Cycle life

To explain simply what is a load round, when you unload a cell and use it to current an appliance, then you load it again with your panels, which is applied to as a load round. The measurement of battery life is through the number of rounds it had produced before it expired, not the period that it operated. 

Imagine the mileage in the car; in the cell, it is the round. Now, an LA-based cell such as this type of accumulator used in a home trailer may push through 100 rounds in half a decade, whereas in other battery types, it may push through 400+ rounds in just a year at a residential house. 

Of course, the cell that has pushed through lesser rounds is much better than a cell that did a few hundred rounds in a year. Now, let’s talk about the base of unload or the amount of load you use before you reload the cell again, as it is common knowledge that the deeper the unloads, the more damages it makes in the internals, which in turn, will shorten the round life of the cell.

The life of the cell will always depend on how you take excellent care of it. Below are images of the range of rounds, cell banks being accurately sized for the loads, and subject to DOD. The temperature will play a significant role, too. The hotter the cell, the shorter its life will be.

Battery capacity also reduces with circulating temperature. The baseline for changes due to the thermal state is 25 degrees Centigrade.

Things to Consider in Buying Lithium Batteries for Home Trailers
  • The Right Weight

Not all cells, regardless of any kind, will vary in size. We know now that LA types are more massive than the Li made, but you still want to be cautious when looking for the right size and weight to suit your needs and your home trailer’s needs. Every camper wants the lightest cell.

The kind of  accumulator that does not consume so much space and is easily transported, too. It is also worthy to note that outstanding Li home trailer cells are typically compact.

There are so many reasons why you should think thoroughly about choosing what type of battery your home trailer needs. Selecting a battery should depend on how you are planning to use your vehicle and how long you are planning to live in it. 

If you are a heavy boondocking camper or love driving off the grid for a long period, you need a cell that can carry on for a few years of use. Not only that, but mobile homes could also have a lot of electrical devices and power-hungry electronics connected to it. 

Therefore, it needs to have a potent cell that can deliver the amperage necessary to start the home trailer and current on its electrical structure. 

Li batteries can deliver up to 2,000 rounds. It means your cell can endure up to two decades if you go boondocking and load your cell as frequently as 100 rounds in a year! 

In this review, you know some types of batteries that are gaining popularity for modern RVs. There are many types of cells, but we will be focusing on LA and Li batteries. LA is a composite of sulfuric acid and leads plates. 

This type of cell was the first reloadable cell they developed in the late 1850s. On the other hand, Li batteries are much more of a modern design that has been commercially available since the 1980s. 

Li technology has become well-established and recognized for energizing small gadgets like portable computers, mobile cells, and other cordless power tools to more extensive cell-driven usage like cars and RVs and can sustain off-grid lifestyles. 

  • Usage Ease

Unlike flooded cells, Li does not vent gas; thus, they do not need to be put up in a vented battery chamber. When it comes to cell usage, a factor that a cell has excellent use ease is its flexibility in charging. 

Owners are always fascinated with the storage manageability and weight that this is always being put aside. Another advantage of Li batteries is that it is mostly compatible with numerous current sources for its charging.

You can quickly load it in a home trailer park current supply, or a residential house. It also can be loaded from unique ways like solar or wind charging. It is always convenient to have a home trailer that can be plugged anywhere or store current from various sources.

Another ease of use is also concerns about the working abilities of the cell. An indicator that it is user-friendly is that the cell works well while the engine is running or parked. The cell should always be based on how you will use your home trailer.

If you are planning to use it frequently while driving, you need a Li battery to support that kind of use. Follow this advice, and you will be thanking us after.

 Another thing to consider that the buyer would always miss is the cell’s current reading. It should be taken into consideration, too, that a cell should have a properly working BMS to 

determine the real-time state of the cells. Consider these things, and your driving should run smoothly.

  • Great Durability

Despite its many advantages, lithium-ion, too, has its drawbacks. It is delicate, and it requires a camouflage circuit to maintain safe performance.

The security circuit is built into each pack and will narrow the peak voltage of each cell throughout charging to block the cell voltage from falling too low on unload. Additionally, as Li can be a bit challenging at below freezing point, the cell thermal state is examined to inhibit temperature extremes.

The supreme load and unload current on most packs are restricted to between 1C and 2C. With these safety measures in place, the probability of metallic Li plating happening due to overload is virtually abolished.

There have been several home trailer owners overestimate the power of the RV, while only basing it on the motor. What makes the home trailer experience better is grasping that the home trailer is only as excellent as the cell energizing it, for what great is a home trailer that is held powerless?

In determining the perfect Li cell for your home trailer, study the products with an excellent reputation for travel durability. In some cases, the elements used in constructing the products affect the very function it delivers.

 It means that high-quality components make more reliable products, particularly in products, respectively, dealing with current and power.

Travel durability decides how many bumps and vibrations the cell would endure on the road, as you face the challenging ground. Whether pressing through old and forgotten country trails or dark beaten paths, your cell should be able to manage all these external factors that can alter its internal functions.

 It will also spell out the cell general life span, which tells you how long your cell can help out your mobile home. The stability of the Li home trailer cell can also allude to the product’s structure. 

Special features are consistently accomplished with various designs that can help the home trailer cell endure the difficulties ahead. Some of the most popular features are sturdy housing design sealed housing, to avoid spillage and tumbling, and various handling characteristics.

  • Power

Another significant advantage of Li batteries is that unlike other cells, Peukert’s losses are non-existent. It means the Li batteries can perform their full rated capacity, even at high currents. In L-acid cells, you can detect a 40% loss of function at high loads.
Compared to L-acid, Lithium battery banks are much more reliable at energizing high current loads like a water heater or an iron. You also want to compare which cell loads fast. 

There are various Li batteries available in the market that can be loaded in an hour. Fortunately, for Li batteries, it has a low self-unload rate. You want a cell that can completely unload without causing damage to the cells.

The most important thing to consider when choosing the right home trailer cell is its current aspect. So take a moment to consider these three whenever you plan to buy: one is the charging speed, because charging speed may affect your entire trip because how far you will get will depend on the current stored in your cell. 

After giving much thought on the charging speed, you should consider the cell capacity itself. Please take a moment to know your Li cell’s ability to store up current, because this will direct the function it can hold. 

How much current it can disperse in a period for the use of gadgets and appliances. Now the final thing you should be giving much thought about in terms of current is the span of a few hours.

Discover how long your Li RV cell can save the unused loads inside it, which can later be utilized when you are on the road.

  • The Right Price

 Budget, as any buyer will know, plays a significant role in deciding which cell to pick. It is a no-brainer to go with this type of accumulator because the Lithium battery is way costly compared to lead-acid to start with. The reason why they differ in cost is because of the materials used to build these L-acid based accumulators. 

With this type of cell, the materials used are inexpensive, and parts to make them are widely available. While in Li batteries, materials are costly, with some parts being hard to find because of the supplies (i.e., Li ).

Another part of the decision-making process to acknowledge is the lifespan of these cells. This is where the initial cost of the Li could be compensated. Another point to consider is the warranty. Of course, you want a cell with a longer lifespan of warranty. 

The longer the warranty shows that the company who manufactured the cell is confident in the product that they are selling. Most companies that sell Li batteries offer a 10-year warranty, and that’s a decade of assurance. Also, be informed of the implications of federal tax rebates.

You might need to familiarize yourself with tax rebates should you want to hook up your cell with a solar system, this deduction will pretty much cover an ample portion of the cost of your cell bank upgrade.

After giving many thoughts in all this, this is the moment you decide on the cost. Weigh out every factor, resolve what kind of home trailer activity you want, and choose what is most suitable for your lifestyle. Getting a Li cell is a long period investment, so the cost should be a factor in determining one. 

What are the excellent cell brands in the market

Although lithium-ion batteries are almost new in the batteries arena compared to the other types, they are quickly achieving popularity because of the high minimal maintenance, quality, and long life. However, if you are still not quite sure which one to get, let us help you. We listed down below some of the time-tested brands of this cell type.


  • Battle Born Batteries – this well-known cell manufacturer’s main office is located in Reno, Nevada. All their products are assembled and experimented in the same facility. Their products work well with current renewable sources such as sun and wind energy.


  • Renogy – this brand manufactures not only batteries but also other RV-related and solar current system accessories. It has been part of the 500 fastest developing companies recognized by Inc. 5000. It’s a reputable brand that has earned numerous excellent Lithium-ion RV accumulator reviews.


  • AIMS Corp – comparable to Renogy, this company’s products concentrate more on solar current systems. They have a full fix of cells, solar boards, inverters, and more. This company was founded in 2001 and sold its products globally.


  • GreenLIFE Technologies – as their name suggests, this company concentrates on green technological solutions. It’s accessible in 30 countries around the world. Most of their cells have what they call a Battery Management System (BMS), which helps inhibit the shortening of a cell’s lifespan. And finally, most of their products have five-year warranties, which say a lot about how assured they are.

How to Determine the Perfect Size

Batteries are very fundamental to RVing. It operates the essential electronic features of the RV, such as the appliances and lights, up to the most complex ones such as the heater, water heater, slides, the tools, and many more. 


Therefore, it is vital to decide the right cell size to provide the right amount of current that your home trailer needs.


Here are some views that can help you determine the right RV battery dimension:


  •  Low maintenance. If you are searching for a cell that doesn’t need to be kept, the most reliable ones are the DC batteries. This type of cell unloads current moderately, so you have more time to energize your devices. Also, if you possess a sun current fixed up, DC cells and chargers are the most suitable choices for you.


  • Premium choice. Li is better in comparison to LA and DC batteries. However, this is also the most costly out of all the options in the market. This one uses Lithium-Iron-Phosphate or LiFePO4. This type of cell reloads quickly and unloads slowly, maximizing every bit of current inside.


  • If your budget is limited, this is the right choice for you. Flooded LA cells usually are the most affordable among the current cell types these days. If this is managed properly, this can function for up to half a decade. The only disadvantage in choosing this cell is that you have to maintain it regularly to lengthen its lifespan.

How to make the cell carry on for a more extended period

A cell typically carries on for 5 to more than half a decade, and that depends on how you take care of it. However, as technology progresses, more discoveries and improvements come along. The most advanced designs of a DC and Li-based batteries can now carry on up to a decade.

How to assemble

Here’s how to assemble up a cell :

  1. Your RV has two cable leads with lugs or eyelets. Attach the red one to the positive (+) wingnut first and the black, or sometimes white, to the negative (-) wingnut of the cell next. Make sure to examine the directions on your unit to confirm the right color of the cables.
  2. Find the positive (+) and negative (-) signs in the wingnuts of the cell.

If you have mistakenly joined the positive to the negative terminals, you will instantly know it if you see a spark.

How to use it

Batteries are more than just current storage. It is also intended to enhance the current supply inside the RV to run more devices or electronic gadgets at the same time.

To use your RV cell, make sure to attach the right terminals. Before attaching the cell, keep in mind to disengage all the current pulls first. This is to avert any accidents while connecting the cell to your RV.

How to care and clean

RV batteries typically need little to no maintenance at all. The only time that you will need to clean it is when the surface gets dirty. The collected dirt can be cleaned off using a dry cloth.

When cleaning the surface of an RV cell, make sure that you use a dry cloth only. 

The wet cloth will increase your likelihood of getting electrocuted while cleaning it. Also, the damp cloth may create the whole electrical bond to a short circuit.


Now that we have run through all the information, we need to know about batteries, especially Li. We can easily assume that Li batteries are more costly, and there is no doubt about that. 

If you go for a compact Li system and unload them up to 80%, they would be 37% more costly, and if you go for a long life and unload them 50%, they would only be 2.5% costly. In all cases, Li batteries have always been higher when it comes to the upfront cost. 

It’s a bit tad challenging to quantify the execution premium connected with Li batteries. The weight will be from 50-75% of this accumulator bank’s comparable type, and volume loss is equivalent. Speed of load and unload, if enormously increased, the current output of Li when used as specified will always be 12.5 volts or beyond.

The Li bank has greater defer capacity because it will still be beyond 12 volts until almost the very end. The AGM cell supply capacity is less beneficial as the voltage gets under 12 volts at 60% unload.  

This type of batteries will need to be substituted more often than Li. It is worthy to note that as this entails time, transportation costs, and installation, which further refutes the higher initial capital cost of Li, as does the lower price of recharging Li.

Whatever cell choice you make, there is also both a technological risk and initial cost at the beginning. If you have the funds for the higher upfront costs of Li, you might find that life is more comfortable, and that choice is a cost-effective one over a while. 

All this depends on the expertise of the operator and how they run a cell system. Good analysis practices are your security against early flop, despite the technology used.

With all of the advantages and comparisons we just cited above, deciding what types of cells will improve your RV’s functionality is now easy to make. Follow these guidelines, and you are good to go.
