This cable connects between a non VE.Bus BMS (Smart BMS CL 12-100 or smallBMS) and a MultiPlus (MultiPlus, MultiPlus Compact or MultiPlus-II).
The cable will turn the MultiPlus off as soon as the BMS has detected a low voltage, high voltage or temperature alarm condition in the Victron lithium-iron-phosphate (LiFePO4) Smart Battery bank. Once the alarm condition has been cleared, the BMS will turn the MultiPlus back on.
