Hi all. Hoping you might be able to help me with an issue with the Victron BMV712. I've added a second battery to the van, and I noticed that the voltage on the Victron app (and the monitor in the van) was fluctuating wildly from around 11V up to 17V. Batteries are connected in parallel and at full charge are 13.5V each.
I hadnt got to the point of changing the battery capacity in the app from 200 to 400amp as yet (as I didnt know at that point that I needed to) so I pulled the batteries out.
Has anyone come across this?
Cheers
