I have just finished an install of Victron Lithium Batteries. I have multiplus 3k 120v which I have programmed the assistants. The BMS is powered by the start battery. When I power on the lithium’s I get a red led indicating over temperature. My batteries both are within range temperature wise and n o alarms. I am afraid to keep commissioning as the next step is to run the alternator which I don’t want to do until I understand the Red led light.
