The upgrade doesnt seem to have fixed that, but has now revealed a different, more serious problem.
On every pack I connect ( 3s upwards ) in balance charge mode, cell two reads WAY lower than actual. Leaving it on balance charge for ages ( which I did first time i saw the readings cos I thought cell 2 WAS low ) changes nothing. I looked at the front pages and read the calibrate charger PDF, but following the procedure , all I get is as far as powering up the charger with the 4 buttons pressed, and all I see is a long serial number, and cant get past that stage ??
Even if I could, I still cant see how this will calibrate the individual cell
volt readings- as it seems to just mention "battery" voltage versus battery voltage on a DVM.
When calibrating, please refer the instruction carefully, don't press 4 buttons together all the time when electrify the iCharger, loose the buttons when hearing 3 beeps from the buzzer.
If the voltage of second cell reads much lower than the actual one, you need check if the balance socket on the right side of the charger is burnt accoding to the file bal err
