The VE.Bus BMS V2 is a Battery Management System (BMS) designed to interface with and protect a single, or multiple Victron Lithium Battery Smart 12,8V & 25,6V (LiFePO4 or LFP) in systems that have Victron inverters or inverter/chargers with 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.

The VE.Bus BMS protects each individual cell of a Victron lithium-iron-phosphate (LiFePO4 or LFP) battery.Each individual cell of a LiFePO4 battery must be protected against over voltage, under voltage and over temperature. Victron LiFePO4 batteries have integrated Balancing, Temperature and Voltage control (acronym: BTV) and connect to the VE.Bus BMS with two M8 circular connector cord sets. The BTVs of several batteries can be daisy chained. Please see our LiFePO4 battery documentation for details. The BMS will: Shut down or disconnect loads in case of imminent cell under voltage. Reduce charge current in case of imminent cell overvoltage or over temperature. Shut down or disconnect battery chargers in case of imminent cell overvoltage or over temperature.
