RV Solar Batteries

Having a dedicated solar battery for RV allows you to enjoy the freedom of camping or boondocking without relying on shore power or noisy generators. It stores energy generated from your RV’s solar panels and powers your essential devices and appliances such as lights, fans, refrigerators, and electronics, even when you're off-grid. These solar batteries ensure that you have an independent energy source during your RV trips.

Lithium batteries, especially LiFePO4, are widely considered the best batteries for RV solar systems. Unlike lead-acid or AGM batteries, Redodo LiFePO4 batteries provide deeper discharges (up to 100% usable capacity), more compact design, longer lifespan (up to 4,000–15,000 cycles), making them more efficient solar energy storage.

The ideal battery size depends on your daily energy usage and how long you plan to stay off-grid. For occasional weekend trips, a 12V 100Ah lithium battery may be sufficient. For full-time RV living or heavy power demands (e.g., refrigerators, air conditioner), you may need multiple batteries totaling 200Ah to 300Ah or more. Additionally, consider whether your RV battery compartment requires specific Group size batteries.

It depends on your power need and usage. For example, if you use around 2,000Wh per day, two Redodo 12V 100Ah lithium batteries (1,280Wh each) can cover your needs. For more appliances or longer trips off-grid, you may need multiple 100Ah-300Ah batteries.

Yes! Redodo lithium batteries are designed for scalability. You can connect batteries in parallel to increase capacity or in series to increase voltage. Always follow connection guidelines and ensure your solar charge controller and inverter are compatible with your configuration.

Yes, Redodo lithium batteries are designed to be drop-in replacements for lead-acid battery, including the same size of Group 24 and Group 31 battery. This means that you’ll get more usable power, less weight, and no maintenance hassles. Just make sure your RV is lithium-compatible or can be adjusted for lithium charging profiles.

Yes, you should use a lithium LiFePO4 charger or MPPT solar charge controller for these lithium batteries. These devices offer the correct charging voltage and profile for LiFePO4 chemistry.

There’s no essential difference between RV batteries and solar batteries. Both of them are deep cycle batteries designed for repeated charging and discharging. Redodo lithium batteries are ideal for RVs, marine, trolling motors, solar setups, off-grid living, and home backup, offering versatile, long-lasting power wherever it’s needed.
