The smallBMS can replace the VE.Bus BMS V2 in several applications. It is however not suitable for use with VE.Bus MultiPlus and Quattro inverter/chargers: it has no VE.Bus interface. The smallBMS is intended for use with Victron Smart LiFePo4 batteries with M8 circular connectors.
The smallBMS has two outputs, similar to the VE.Bus BMS V2.
