ABYSS 48V125AH LITHIUM MARINE HOUSE BATTERY *DROP SHIP ITEM*

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.
