6 Top RV Battery Recommendations in 2024

An RV battery powers everything from your lights and water pump to your fridge and outlets when you're not hooked up to shore power. But not all RV batteries are created equal. In this guide, we'll break down the best options and share our RV battery recommendations with you.

Why Choose LiFePO4 Lithium Batteries for Your RV?

Here’s why LiFePO4 (Lithium Iron Phosphate) batteries stand out as the ideal power solution for RV:

Longer Lifespan

LiFePO4 batteries offer a significantly longer lifespan compared to lead-acid batteries, with over 4,000 cycles at 100% Depth of Discharge (DOD) and a service life of up to 10 years. In contrast, traditional lead-acid batteries typically last only 2-3 years.

Lightweight and Compact

LiFePO4 batteries are significantly lighter than comparable lead-acid batteries. For instance, a Redodo 12V 100Ah Group 24 LiFePO4 battery can weigh as little as 22.16lbs, making it much easier to handle and freeing up weight in your RVs.

Higher Energy Efficiency

The LiFePO4 batteries have a higher usable capacity, typically providing 100% of their stored energy. While lead-acid batteries are greatly affected by the discharge current. They can only provide about 50% of usable energy under 1C discharge current.

Fast Charging

LiFePO4 batteries charge faster than lead-acid options. For example, a 12V 100Ah battery often reaches full capacity in 5 hours or less by a 12V 20A LiFePO4 battery charger. 

Eco-Friendly and Low Maintenance

Unlike lead-acid batteries, LiFePO4 batteries don’t require regular maintenance like adding water, and they have no toxic materials, making them safer for the environment.

How to Choose an RV Battery?

Here are the key factors to consider for choosing the best lithium battery for RV:

Battery Type

Lithium (LiFePO4) and lead-acid (AGM or flooded) are the main types. Lithium batteries last up to 10 years and offer over 4,000 cycles, significantly outlasting lead-acid, which typically lasts 2-3 years with 200-500 cycles. Though lithium batteries cost more upfront, they provide better long-term value.

Capacity and Power Needs

Capacity, measured in ampere-hours (Ah); energy, measured in kilowatt-hours (kWh). For example, a 12V 40W fridge uses 0.96kWh, which about 75Ah per day. A 100Ah RV battery can power the 12V fridge for approximately 32 hours before needing a recharge.

Weight and Size

Space and weight are key considerations for RVs. Lithium batteries are generally much lighter than lead-acid batteries of the same capacity, making them ideal for compact setups. Make sure your RV space can accommodate the battery size. The common RV battery sizes are Group 24 or Group 31 battery.

Charging Speed and Compatibility

Lithium batteries charge much faster than lead-acid options. For instance, a lithium battery can fully charge in 5 hours or less, while lead-acid batteries may take 8-12 hours. Also check that your charging system—solar panels with MPPT, DC-DC charger, or AC-DC charger—is compatible with the battery type you choose.

Battery Management System (BMS)

A built-in BMS helps protect against overcharging, over-discharging, short circuits, overcurrent, and overheating, ensuring safety and extending battery life. Features like low-temperature cutoff protection are beneficial if you plan to camp in colder climates. Check out to learn more about Redodo low-temp batteries.

Power Expandability

For future power needs, consider batteries that support series-parallel configurations. Some Redodo models can expand up to a 4P4S configuration, providing as much as 4x energy for extensive off-grid use.

Tips for RV Battery Maintenance

Here are key tips to maintain RV battery and keep it in optimal condition:

Avoid deep discharges

For lithium batteries, it's recommended to recharge before dropping below 20% capacity. When not in use for a long time, store your battery at a 50% charge level and recharge every three months to prevent capacity loss.

Monitor Battery Health

Check voltage levels and charge/discharge status routinely. Some smart lithium batteries with Bluetooth, like the Redodo 12V 100Ah Group 31 Bluetooth battery, enable easy tracking via Redodo mobile app, helping you manage power usage and detect issues early.

Avoid Extreme Temperatures

Batteries perform best between 59℉ and 95℉ (15℃ to 35℃). In high temperature environments, the BMS of LiFePO4 batteries have high temperature protection. For cold conditions, the batteries with low-temp charging cutoff can prevent damage from extreme temperatures.

Proper Storage 

When storing your RV batteries in short term, disconnect the battery and keep it in a cool, dry place. Lithium batteries should be stored at around 50% charge to maintain health. Avoid leaving them at less than 20% charge for long periods.

Check Terminals Regularly

Inspect terminals every few months to ensure that the connections are tight. If the terminals are loose, tighten them promptly with insulated gloves. Tighten connections for optimal energy flow.

Use the Right Charger

Always use a charger designed for your battery type. For example, use a LiFePO4 battery charger charging a LiFePO4 battery to ensure the safety.
