The Victron Lithium NG Smart Battery is a 25.6 V, 200 Ah lithium iron phosphate (LiFePO4) battery with 5120 Wh of nominal energy. Batteries can be connected in series, parallel, or series/parallel to build a bank for 12 V, 24 V, or 48 V systems. A system can have up to 50 batteries, for up to 384 kWh in a 24 V or 48 V system.
The battery has an integrated shunt and integrated cell balancing and cell monitoring. Battery voltage, current, and temperature go to the BMS, which calculates the state of charge and issues warnings and alarms. A Lynx Smart BMS NG 500 A/1000 A is required and must be purchased separately. It detects the system voltage and the number of batteries automatically and updates the battery firmware. You can monitor it in real time through VictronConnect (Bluetooth), a GX device, or the VRM Portal, including cell voltages, current, and temperatures.
The BMS gives a pre-alarm when a cell drops below 3.0 V and disconnects the load below 2.8 V. It stops charging when a cell rises above 3.6 V or when the temperature is too high or too low. The case is sealed against dust and low-pressure water jets (IP65). The battery can be mounted with a strap or with mounting brackets, and it can be placed on its side.
