Update on iWatRoad scooter

Once I replaced the melted XT60 battery connector in the R9 iWatRoad scooter, the user interface powered up. While the battery measured full 42V, the display said it was empty. So I wired it up to a lab PSU that could provide no more than 400 mA at 42V. It did take current for some 10 minutes and then stopped, still showing empty battery. When we plugged the original charger the LED stayed green, meaning "it's charged".
I think the culprit now lies inside the heatsink box that holds the control board. It is glued to the chassis and it will be removed sooner or later, to have a look inside or to look for a replacement.
Wired-up for charging.
