I flashed the firmware successfully with a PicKit4 and MPLABS and took a dump of the EE-flash before I uploaded your firmware.
It works fine, but the problem is the battery dies around 3.6V although the delta is maximum 0,02V.
Also, it doesnt charge although the power supply is plugged in and the light is blue. There is a funny yellow/white flash as I plug in the charger before it goes blue.
I'm currently back to charging the individual cells
