That driver board has a lot of bad solder joints on it...

This one?

Use loup if you have one put some clean solder on the joints where
the power fets are especially.

Whilst I agree they don't look very pretty I do have a loup and have
just given it a look over and *I* can't see anything obvious ... but
then I many not be able to spot something that is obvious to others.
;-)

If I'm there re-doing the joints I might as well take the FETs off one
at a time and put them in my tester and see what it says? Or at least
do the two that don't seem to be involved in the charging (that I
believe works etc).
