I am using a bq30z554 with a 3P3S cell arrangement. When I am building a brand new pack, the first charge is being terminated when RSOC reaches 100%, but I can see the charge current hasn't reached close to its taper current and the cells have not reached the charge voltage. If I turn off the TCASETRSOC and FCSETRSOC bits in the "SBS Data Config" register, the pack terminates charge due to an overcharge condition.
Should I leave these configuration bits high and run more charge/discharge cycles? I have run a couple cycles with 5 hour delays between, and the remaining capacity is still much lower than my design capacity. I'm thinking this is because the pack is not fully charging. Could this be correct?
