I have a fairly standard electrical set up for the habitation side of my camper. !00Ah battery, a Victron 75/15 mppt controller and a BM1 battery monitor. It works fine and I'm happy with it except that I noticed the BM1 was showing battery voltage at 13.6 volts towards the end of the day. I checked that the Victron was in float mode as expected given that I hadn't used the van that day and that the float voltage in settings was set to 13.8 volts which was the voltage I expected to see on the BM1. I checked the voltage at the battery with a voltmeter and sure enough it was 13.6 volts.
I then increased the float voltage setting in the Victron to 14 volts and both BM1 and measured battery voltage rose to 13.8 volts.
Where is my 0.2 volts going? Should I leave the Victron float voltage set to 14 volts? Does it matter?
