ABYSS® 48V125Ah Lithium Marine House Battery

Silent, high‑voltage power for electric propulsion and true generator‑free living aboard. Meet the house battery that lets you cruise, anchor, and sleep without the drone of a genset. Built around a 51.2V LiFePO₄ pack and a robust marine BMS, this 6.4 kWh module is purpose‑engineered for electric propulsion and high‑demand DC/AC house loads—then sealed to IP67 so it actually belongs on a boat. It also speaks Victron natively over CAN, so your inverter/charger and GX devices coordinate charge limits and currents automatically for a clean, alarm‑free system. Why choose this battery? Generator replacement: Pair with a Victron inverter/charger and you’ve got quiet AC overnighting, galley loads, and thrusters without burning diesel. Victron‑protocol CAN comms coordinate CVL/CCL during charging and taper current as the pack fills—exactly how it should work on a yacht. Serious energy density: 51.2 V × 125 Ah = 6,400 Wh in a single module designed for parallel scaling. (Series connections are not supported; keep modules at the same voltage before paralleling.) Marine‑ready build: IP67 enclosure, CE/UN38.3 compliant, with integrated BMS protections for over/under‑voltage, over‑current, temperature, and short circuit. Victron protocol compatible: CANBUS + RS‑485 on board for plug‑and‑play integration with Victron inverters/chargers and GX devices. Installer‑friendly: Clearly labeled IN/OUT, charger/motor comm ports, remote/wire‑control switch option, and busbar guidance—including fuse and gauge recommendations. Key specifications Nominal voltage / capacity: 51.2 V / 125 Ah (LiFePO₄); Stored energy: ~6.4 kWh. Voltage range: ~40–57.6 V (CC/CV charging at 57.6 V).
