Hello all you knowledgeable sphere people, built my bro an ebike he never looks after his stuff so was not surprised when year later he said broken,
At first no output from battery or charging 48v Panasonic 13s,
So I opened it up, bingo, negative output had come of the bms, soldered that back on
Now battery charges, and outputs power
But the power switch does nothing at all, tested switch and it works, is it time for a new bms..? Any opinions appreciated thanks
