Yes, do check the 12V before anything else.
There is someone in the Bay Area that does repair on these boards, through Luscious Garage. An engineer checked out the board and found, IIRC,...
OK John, thanks. I guess the question is about that "for some reason" aspect that makes one cell fall out of sync. Over the life of a typical...

Where are you located? That may make a difference.
