I have a 300ah victron lithium battery, and a smart BMS CL 12/100 setup in a van. While I was on holiday it has discharged and I can now only bluetooth connect to the BMS.
The BMS reads the battery at only 3.5v. I usually charge it by hooking up a mains charger to the van battery, which then goes through the BMS as "alternator" charging. But now that does nothing, the BMS says alternator charging is "disabled by the battery". How can I wake it up? Should I directly put a mains lithium smart charger on it and ignore the BMS?
