Hello, I have a LifePo4 battery with BMS and I’m monitoring it with the BMV702.
Every time the battery runs off and shuts down, I lose data on the BMV so the SOC is always needing to be reset by a full charge and I don’t see the ‘last discharge’ data.
I’m planning to use the relay to switch off appliances before it gets to a full discharge, but is there another way to maintain power to the Victron, perhaps with the starter battery, or another independent source to keep the BMV on?!
I’ve got a 24v leisure battery.
