Ok you are charging to 14.2 which is good.Just re-read the thread and you’ve highlighted that I should only be balancing while charging and above float voltage. I don’t recall what the charge voltage is but absorption is 14.2 so assume that to mean it charges to that point. Now, float is set to 13.5 but the BMS balancing is set to start at 13.4. Might need some fine tuning.
First picture is the BMS configuration, second is the charge controller.
Try incrementing by .1 volts every few days to to see if the balance improves.
14.6 is dead full and you will probably get a high cell disconnect if you try for 14.6.
I would stop at 14.4 volts.
Set the charger to float at 13.4 or lower and set the bms to start balancing at 13.5.
