MiniBMS for Victron Lithium Smart batteries

The VE.Bus BMS protects every single cell of a lithium iron phosphate (LiFePO4 or LFP) battery.
Every single cell in a LiFePO4 battery must be protected against overvoltage, undervoltage and overtemperature. Victron LiFePO₄ batteries have built-in cell balancing, temperature and voltage control (hence the acronym: BTV). They are connected to the VE.Bus BMS via two M8 round connector cable sets. The BTVs of several batteries can be chained together. For further details, please refer to the technical documentation for our LiFePO4 battery.

Tasks of the BMS:

• Switching off or disconnecting loads in the event of an imminent cell undervoltage.
• Reduction of the charging current in case of impending cell undervoltage or overtemperature (only for VE.Bus products, see below).
• Switching off or disconnecting the battery chargers in the event of an imminent cell overvoltage or overtemperature.
