I don't get paid for my videos but do get paid on completed purchase from these links so if you want to help me out

I show you how to open the battery and I check all the batteries one by one to make sure none are faulty and need replacing. then I test everything else to discover the battery management board is faulty and I ordered another from Ali Express.

6:30 Lets test it with the charger fitted now.
6:49 no red or blue lights with the charger fitted, looks to be a PCB fault.
7:43 Testing the outputs when charging there is voltage, when the led flashes.
7:57 there should be about 20volts on the outputs
10:50 Another charger to test one I know works.
12:08 Just trying it again but no luck.
12:42 These two match up.
12:48 And theses two
13:00 there is a fault with this board.
13:17 I try heating up the board hoping that the solder will reflow if theres a bad joint
13:54 but theres a varnish to waterproof the board and this burns.
