Since the lifetime over my Overkill Solar BMS, I have noticed that the Total Capacity value changes from 500AH to 450AH after some time. I will log back into the BMS, make the change back to 500AH and after a period of time it will happen again. I top balanced the cells and have no other problems (other than the BMS showing a pretty different state of charge (30% vs 60%) than my Victron Shunt.

Any ideas if this is indicative of a problem or just poor firmware?
