LiFePO4 Lithium Batteries for RV, Solar & Marine | Jonsson

Lithium iron phosphate (LiFePO4) batteries deliver 3–5× the usable capacity of a comparable lead-acid bank, last 8–10× longer, and weigh roughly a third as much. Whether you're building an RV house bank, a marine service bank, an off-grid cabin, or a 48V rackmount energy storage system for a home solar install, we carry batteries to match.

Our lineup includes Victron's LiFePO4 NG and Lithium SuperPack series (12.8V, 25.6V, and 51.2V — sized from 60Ah up to 300Ah), AES rackmount 48V batteries for grid-tied and hybrid solar systems, and Renogy 12.8V batteries for budget-conscious RV builds. Cold-weather builds: ask about the DuoHeat self-heating models. We'll help you size your bank, pair it with the correct inverter and MPPT, and design the bus-bar and fusing — free with every order.
