What is your hardware setup like? Might be useful to check the bus with a logic analyzer.

It seems it fails on reading charger status. I have generic cp2112 CJMCU board which have different pins. It works correctly with BE2Works demo and seems to work with this demo just not clear how the charger has to be communicated.

the charger is different SMBUS device so if you quaering battery only it's expected it would throw "charger SMBUS read error". It would be better to change this error message to something like "charger not connected".
