Tired of heavy lead-acid, slow charging, and uncertain state of charge? Our rv lithium battery brings dependable energy in a compact form—with built-in BMS and mobile app monitoring—so you know exactly how much power remains, anytime.
Multi‑level protection (over/under‑voltage, over‑current, over‑/under‑temperature, short‑circuit) and cell balancing. Custom profiles available.
See SOC, cycles, voltage, current, temperature, and alarms from your phone for transparent energy management.
Safely charge down to −20 °C (−4 °F) with integrated self‑heating and firmware control. Standard packs: charge ≥0 °C.
Up to 50% less weight vs. lead‑acid equivalents—free up payload for gear and water.
Max charging current up to 1C (model dependent). Typical full charge in ~2–3 hours with adequate charger.
No Pb, Hg, Cd in cells; lower replacement frequency reduces lifetime waste.
