Replacing cells 18650 in Ryobi battery pack

What kind of nickel did you use

[@test-193]

Nice video! Can I offer a suggestion? When connecting the BMS wires to the cells, you should connect them in increasing voltage. e.g. first connect the 4.20V wire, then the 8.40V wire, then 12.60V wire, then the 16.80V wire, then lastly the 21.0V wire.

Yes I know, I usually do this to test BMS are working, however this is risky to other who might use broken BMS, so I don't share this video, I don't want any of the watcher to do some mess in their homes

0.15 mm nickel is insufficient for the continuous 50A parallel pairs of these cells can deliver. You should at least weld another strip on top of the first one to avoid excessive heat build up and current limiting.
