What Is A Lithium Battery For RV/ How Does It Work


Lithium-ion RV batteries fall under the broad category of RV house batteries, a type of deep-cycle battery.

They are inherently different from engine batteries and ordinary batteries in regular vehicles. Compared to them, deep-cycle variants are more powerful and pricier as it can store energy for a specified period.

With this, users can comfortably use energy off the grid, sans a 110-volt power supply. They are especially ideal when used in remote locations or places where electricity is scarce or fluctuating. Some deep-cycle batteries are even utilized in marine areas such as in boats, ships, etc.

Deep-cycle batteries are ideal when one has a lot of power-hungry appliances in the RV, such as induction stoves, air conditioners, refrigerators, ovens, and the like. This battery provides a lot of power while also having a fast recharging rate.

Lithium RV house batteries are usually composed of cells wired together, containing the energy needed to start the RV and for other purposes.

When one turns the key in, the energy inside the cells reacts and changes into electrical power. This energy is then transported to the starter to start up the RV and use it on the appliances.

A fully-charged lithium ion RV battery can hold about 12.6 volts or more. If it’s still within the 12.1-12.5-volt range, then it indicates that the battery is only 50% charged while any voltage below that would mean that it needs to be replaced and charged.

Types Of RV Lithium Batteries


As already stated, lithium RV batteries fall under the spectrum of the popular deep-cycle batteries. This section will list all the different types of deep-cycle variants.

Flooded Lead-Acid Batteries

It also goes by wet-cell batteries. This type is considered the most popular and most accessible as they are comfortable and cheap to manufacture. As such, they are quite affordable and easy to use.

Flooded lead-acid batteries contain electrolyte fluid that surrounds and submerges lead plates. Because of this, these battery types rarely overcharge and provide large amounts of power. They are also quite long-lasting; however, they do require constant maintenance.

Absorbed Glass Mat Batteries

AGM batteries also contain electrolyte fluids; however, instead of lead plates, the liquid is held by glass mats. Compared to lead-acid types, AGM batteries charge five times as fast and are ideal in numerous applications.

These battery types are also sturdy, having lower internal resistance and high-temperature resistance. AGMs don’t require constant maintenance, and you can safely store them for long periods without worries.

Gel Batteries

Gel batteries are known for their gelled electrolyte, which gives a leak-free design. With this, they are also quite simple to install and use as well as maintain.

However, these types are sensitive to high temperatures and are prone to breaking down when overcharged.

Lithium-ion Batteries

Lithium-ion batteries are one of the most popular types since they are quite durable and provide excellent performance. As such, they are used in numerous applications but are often seen in RVs and motorhomes.

Lithium batteries for RVs are favored as they have high voltage levels, which can provide up to 99% power capacity. They are also lightweight and efficient, reaching up to 5,000 life cycles.

Those types of batteries are durable as they can withstand extreme temperatures and even come with an auto-shutdown feature. Lithium-ion batteries are also easy to install and use.

Benefits Of Using A Lithium Battery For RV

This section will list down all the advantages and disadvantages an RV lithium battery might provide.


  • Constant Voltage

Voltages of other deep-cycle batteries tend to fall as the electrical load increases. Because of this, the power they provide isn’t constant.

However, lithium-ion batteries have constant voltage, which means that it will provide peak power regardless of the electrical load. With this, you can comfortably use your appliances without any worry.

  • Higher and Faster Charging Rate

Other deep-cycle batteries tend to get damaged when charged quickly. However, lithium-ion batteries don’t have that problem.

Due to their construction, lithium batteries can accept over up to 100 amps or about 100%-200%, without suffering from any damages. It can even be safely recharged again and again, without any hitches.

The only limitation to this is the RV’s charging source.

  • Size and Weight

Compared to other deep-cycle batteries, lithium-ion variants can pack 3 to 4 times more energy than batteries of similar weight and size. This is especially beneficial for those with smaller RVs and motorhomes.

  • Low-maintenance

Because of their construction and design, lithium-ion batteries do not require much maintenance and care, as compared with their counterparts.

  • Easy to Install

Lithium-ion batteries can also be installed virtually anywhere and in any position, except upside-down, thanks to their design and build. With this, you’ll have the adaptability you’ll need when installing it in your RVs or motorhomes.

  • Safe

Lithium-ion batteries are also safe and non-toxic when used correctly. As such, you wouldn’t have to worry about spills, fires, or toxic fumes.

They can also be left unattended for a long time due to their low-rate of self-discharge. This ensures that you wouldn’t have a dead battery.


  • Limited Distribution

Lithium ion batteries for RVs are distributed via only individual vendors and stores. As such, you might have a hard time purchasing them. This would also mean these batteries tend to be expensive due to limited stocks. Still, you can find them in many online marketplaces and manufacturer websites.

  • Management

These batteries require individual monitoring. You need to ensure that each cell is equally charged and that both the voltage and current are kept within a safe number. Otherwise, the whole system will suffer.

How We Picked


Lithium RV batteries are quite popular due to their superb performance and high quality. There are numerous brands and types available in the market that might make it difficult and confusing for beginners and even veterans.

However, you don’t have to worry. This guide will list down all the qualities and attributes you need to check when looking for lithium-ion batteries for RVs.


A battery’s capacity is indicated in Ampere hours (Ah), which points to the amount the battery can provide for some time.

Of course, high-capacity batteries are preferred as they can store and supply power for more extended periods. However, you’ll also have to take note of the weight as high-capacities translate to larger and heavier batteries.

First, to determine the capacity, compute your RV’s daily energy requirements, and leave some extra allotments. When choosing a battery, ensure that the battery can supply power without dropping to 50%-60% of its total capacity.


An RV lithium battery often comes in 12-voltage variants, which are generally adequate for everyday use. However, if you need more power, you can add 6-volt batteries to the current set-up.

On the other hand, a lithium-ion battery for RV solar usually requires a power inverter to convert DC to AC.

Discharge Depth

This refers to the battery’s state of charge, which is the available capacity in your battery. Take note that the discharge depth is crucial as it points to the battery’s life cycle. The life cycle indicates the number of charge/discharges cycles the battery can handle before its performance drops under 80%.

It’s recommended that you choose a battery that can optimize its life cycle with its depth of discharge.

Size and Weight

The battery’s size and weight doesn’t matter as modern RVs and motorhomes come with massive battery compartments that can accommodate both default and extra batteries.

However, bigger batteries tend to mean larger amps and reserve capacities. Meanhwile, lightweight batteries are also easier to handle and maintain.


Generally, lithium batteries for motorhomes can last for five years. However, this number can change depending on numerous factors such as maintenance, temperature, usage, and the like.


The battery’s overall construction and build is essential as this affects its lifespan. It’s ideal to find a model that can withstand shocks and vibrations; however, this can be quite expensive.

Otherwise, subpar models would just entail more costs in the long-run due to constant repairs. You’ll have an idea of the battery’s durability by reading lithium-ion RV battery reviews and research.


Pick batteries that can still perform efficiently under extreme temperatures, especially when you tend to camp or travel during cold/warm months. With this, you’ll have a steady supply of power. It’s also ideal to find a battery with an auto-shutdown feature for safety.
