I have seen different cell voltages reported when using HobDrive vs CanIon, but the DCTs do match with a 100mV difference on some cells on CMU9, just a warning though, the car will be able to correct this over (a long) time.The power supply warnings are probably because your ‘dodgy’ OBC isn’t boosting the Aux voltage to 14.4V and therefore not charging the 12V battery either. Not sure how long this has been going on but I agree it’s time for a new one, fully charge it before installation and top it up regularly if the OBC can’t do it.
