Victron VE.Bus BMS f/Victron LiFePO4 Batteries 12-48VDC Works w/All VE.Bus [BMS300200000]VE. Bus BMS for Victron LiFePO4 Batteries 12 48VDC Works with All VE. Bus 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
