VE.Bus BMS NG, BMS300200300, Victron Energy - The VE.Bus BMS NG is an all-in-one Battery Management System (BMS) for Victron Lithium NG batteries (not compatible with Lithium Battery Smart batteries), designed for systems with Victron inverters or inverter/chargers using VE.Bus communication. It monitors and protects the batteries against over voltage and under voltage of any individual cell, and also over temperature or under temperature conditions. With built-in Bluetooth, the BMS provides central monitoring via VictronConnect. The BMS derives all key parameters including voltage, current, state of charge and individual cell data directly from the battery, removing the need for a separate SmartShunt. The lithium NG batteries can be configured in series, parallel, or a combination of both
