Having a ‘little’ problem here I was recently working on my battery because the negative lead had come loose of the BMS.
Now I managed to create some sparks from shorting by letting the negative battery lead touch one of the MOS FETs on the BMS. (see picture) the middle lug of the MOS FET has the most ‘damage’.
This caused some colouring on the solder, but worse is probably that it seems to be the cause of my BMS not fully charge the battery anymore (stops around 68% or 37volts)…
Could this easily be fixed? Like replacing that MOS FET. Or could it be the case that more hardware is affected? I don’t have a voltmeter yet to test things, but maybe you can give some direction in the matter!
