I wanted to update this thread on the status of the Battery. I started to notice in the last few days to a week, that despite having over 10-12km on the freshly charged battery, I still have a high voltage reading. Suspecting that perhaps, the BMS "fixed" the weak cell, I checked the weak cell and compared it to the others. It was only off by 0.01 - 0.02 Volts.
The only thing I've done differently, is I leave the pack on the charger for a few hours after it's done the charge cycle, vs removing the charger right away. Perhaps this properly balanced the cell over time ??
I would need to run it close to, or to Low Voltage Cut off to be sure.
