However, it is not suitable for use with VE.Bus MultiPlus and Quattro inverter\/chargers, as it lacks a VE.Bus interface. The smallBMS is designed for use with Victron Smart LiFePo4 batteries with M8 circular connectors.\u003cbr\u003e The smallBMS has two outputs, similar to the VE.Bus BMS.\u003c\/p\u003e \u003cp\u003e\u003cbr\u003e \u003cstrong\u003eLoad Disconnect Output\u003c\/strong\u003e\u003cbr\u003e The load output is normally high and becomes floating if the cell voltage is too low (default 2.8 V\/cell, adjustable\u003cbr\u003e on the battery between 2.6 V and 2.8 V per cell).
