Victron Energy – 12V/100Ah Lithium LiFePO4 NG Battery | BAT512110620

The Victron Energy Lithium NG 12.8/100 is a 12.8V 100Ah Lithium Iron Phosphate (LiFePO4/LFP) battery with 1280Wh of nominal energy. Lithium NG batteries feature an integrated shunt, allowing battery voltage, current and temperature data to be transmitted to the required BMS for state-of-charge calculation, monitoring, warnings and alarms.

The Lithium NG series is designed for use with the Lynx Smart BMS NG 500A or 1000A, which must be purchased separately. System monitoring and control can be performed through VictronConnect, a GX communication centre or the VRM Portal. Bluetooth functionality is provided through the BMS rather than directly through the battery.
