Collection: LiFePO4 Batteries For RVs & Cabins

Store the power your solar system generates with a deep-cycle LiFePO4 (lithium iron phosphate) battery built for RV, cabin, and marine use. This collection ranges from a compact 12V 18Ah battery (216Wh) suited to small electronics or a starter setup, up to the ROCKSOLAR 12V 200Ah (2560Wh) and Dakota 48V 74Ah (3552Wh) packs for running a fuller RV or cabin electrical system through the day and overnight.

LiFePO4 chemistry is the standard choice over lead-acid or AGM for this kind of use: it holds a flat voltage curve through most of its discharge cycle, so your appliances get consistent power right up until the battery is genuinely low, rather than a slow fade. It's also safer to store deep-discharged or at partial charge — most LiFePO4 batteries do best kept around 40–60% for long-term storage — and every battery in this collection includes a built-in BMS (battery management system) for protection against overcharge, over-discharge, and short circuits. All are compatible with solar panel charging, so they drop straight into an existing or new RV/cabin solar setup.
