The BMS is designed for use with Victron Lithium Iron Phosphate batteries. Its function is to manage the battery bank and prevent overcharging or over discharging.

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. Up to five batteries can be paralleled and up to four batteries can be series connected (BTVs are simply daisy-chained) so that a 48V battery bank of up to 1500Ah can be assembled. 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 over voltage or over temperature (VE.Bus products only)
  • Shut down or disconnect battery chargers in case of imminent cell over voltage or over temperature.

    Protects 12V, 24V and 48V systems

    The operating voltage range of the BMS: 9 to 70V DC.

    Communicates with all VE.Bus products

    The VE.Bus BMS connects to a MultiPlus, Quattro or Phoenix inverter with a standard RJ45 UTP cable.

    Other products, without VE.Bus can be controlled as shown below:

    Load Disconnect

    The Load Disconnect output is normally high and becomes free floating in case of imminent cell under voltage. Maximum current: 2A.
    The Load Disconnect output can be used to control

  •  the remote on/off of a load, and/or

  • the remote on/off of an electronic load switch (Battery Protect)

         Charge Disconnect
       
The Charge Disconnect output is normally high and becomes free floating in case of imminent cell over voltage or over temperature. Maximum current: 10mA.
The Charge Disconnect output can be used to control
  •  The remote on/off of a charger and/or
  •  a Cyrix-Li-Charge relay and/or
  • a Cyrix-Li-ct Battery Combiner

         LED indicators

  • Enabled (blue): VE.Bus products are enabled.

  • Cell>4V or temperature (red): charge disconnect output low because of imminent cell over

    voltage or over temperature.

  • Cell>2,8V (blue): load disconnect output high.
