Best LiFePO4 Batteries for RV House Banks

Amp-hours determine how long your battery lasts per charge. For rv house battery, we recommend at least 100Ah.

12V batteries are standard for RVs, boats, and small cabins. 24V and 48V systems are more efficient for larger installations (less current = thinner wires, less loss). Match voltage to your inverter and charge controller.

Watt-hours is the true measure of stored energy. Calculate your daily consumption in Wh, then size your battery bank for 2-3 days of autonomy. A 100Ah 12V battery stores 1,280Wh of usable energy.

LiFePO4 batteries deliver 3,000-5,000 cycles to 80% capacity. At one cycle per day, that is 8-14 years of service. Cheaper batteries with lower cycle life cost more per kWh over their lifetime.

LiFePO4 batteries weigh roughly half of equivalent lead-acid. Weight matters for RV and marine applications where payload capacity is limited. A 100Ah LiFePO4 typically weighs 24-30 lbs vs 60+ lbs for lead-acid.

Higher continuous discharge amps support larger inverter loads. A 2,000W inverter on a 12V bank draws ~170A. Verify your battery can sustain the current your inverter demands without BMS cutoff.

Series connections increase voltage (e.g., two 12V batteries = 24V). Parallel connections increase capacity (e.g., two 100Ah = 200Ah). Verify the BMS supports your wiring configuration and check maximum number of parallel units.
