I have a DIY battery with a ant bms. I added a victron BMV monitor with a (ve.direct cable) to get SOC for ICCsoftware with a axpert inverter).
Problem i am having is that the bmv over time looses the correct state of charge (compared to the BMS which appears to be more correct)
Overtime the BMV shows a lower SOC compared to what the battery actually is. (when cells get to around 3.4 they should be showing near 100% SOC on the BMV)
Not sure if anyone know the correct settings on the BMV.. there was a long list, i guessed most of settings so not sure what others have used.
I charge the battery to 54.4v which should be close to 100% SOC right..?
Still need to spend time fine turning the BMV, thought I could start here:)
Many Thanks,
Ian
