For Victron Energy Lithium iron phosphate (LiFePO4 or LFP) battery only.

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.

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 (VE.Bus products only, see below).
  • Shut down or disconnect battery chargers in case of imminent cell overvoltage or over temperature.

Technical information:

  • Input voltage range: 9-70V DC
  • Current draw, normal operation: 10mA (excluding Load Disconnect current)
  • Current draw, low cell voltage: 2mA
  • VE.Bus Communication port: 2 x RJ45 sockets to connect to all VE.Bus products
  • Protection: IP20
  • Dimensions: 105 x 78 x 32 mm
  • Weight: 0.1 kg
