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.
Based on the status of the battery or batteries, the BMS will:
