Victron Lithium NG 300Ah Battery, 12.8V

The Victron Lithium NG (Next Generation) battery series is the latest generation of Victron lithium batteries, featuring built-in digital communication. Each battery has an integrated shunt that continuously measures voltage, current and temperature, feeding real-time data to the battery management system (BMS) — monitor everything from the VictronConnect app or a GX device via the VRM portal, right down to individual cell data, with fully configurable alarms.

A higher IP rating gives the battery improved protection against dust and moisture, and combined with the flexible console mounting option this makes for a clean, space-saving installation even in tight engine bays where a traditional lead-acid battery simply wouldn't fit.

This 300Ah Lithium NG battery is a modern LiFePO4 cell that can be wired in series or parallel to build 12V to 48V systems with up to 384 kWh of total storage — a serious upgrade path for a larger boat's electrical system. Self-discharge is only around 2% per month, making it a good choice for winter storage without constant maintenance charging. Note: the battery requires a compatible BMS (sold separately, e.g. Victron Lynx Smart BMS or VE.Bus BMS) for safe, fully functional operation.
