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?

Hello, The SOC and the capacity on the app incorrect.
all SOK 12v 100Ah real capacity would be around 105Ah.
