12V - 400Ah LiFePO4 RV and marine batteries with 5,000+ cycles, built-in BMS and low-temperature heating. Safe, lightweight house power for off-grid trips and boats.
Request a QuoteRV and boat house banks take vibration, temperature swings and partial-state-of-charge abuse that kills lead-acid fast. LiFePO4 handles all three: it is lighter, charges from solar and alternator without memory, and keeps delivering near-full capacity in cold weather when paired with a heated version. This guide explains bank sizing, heating and what certifications matter for marine use.
