Hello, I built a powerwall for emergencies and to run an AC unit, and other electric gadgets, it has a 5KW capacity or close to that. I use the Victron's 150/35 Charge Controller with BT adapter, it is working great. The question I have is about the profile, for my batteries, during charging the app shows 41.5 volts at around 6-12 amps, then tappers down, before going to float, when I look at the history the battery max voltage shows around 42.60 volts, when I check the voltage at the batteries it shows it 41.5 volts, what could be the cause for the app to show a higher voltage than the batteries show at the terminals? i would like to set the charging to 90% of the battery capacity which should be around 41-41.5 volts, so should I trust the app reading versus the battery terminal reading? is there a modification to the profile that will correct that? Thanks
