Hi, abc-bms app seems to have conflict on 5th 100ah sok battery when hooked in parallel with 4 others -it works fine when battery is on its own but when parallel with 4 others it shows correct status very briefly -like 1 second then freezes with current then showing zero and volt way off- measuring with voltmeter shows ok functioning- each time you search and connect you get 1 second of correct reading so you have to be quick!! Looks like software bug to me?

I have 4 100ah sok in parallel working fine but actual capacity field in bms app varies a lot - one shows 107ah, one 87ah, one 77ah and one at 74ah- this stays about the same regardless of soc -they do all charge to 100% -Is this variation a sign of imbalance? Individual cell voltages are all very similar across all 4 batteries. Is this a problem? Shoudnt they all show actual capacity close to 100ah?
