Battery Instruction. How to make a battery not blow up.

Retire and properly recycle the pack when it starts running hotter, exhibits any weird behavior (not due to the BMS), or its voltage starts sagging a lot more.

unless the pack is absolutely rigid there will be micro movements of the cells and stress on the spot welds. This creates metal fatigue and can lead to increased weld resistance (and heating) and eventual failure of the weld.

I would love to see weld comparison between Kweld/Sequre/Sunkko/Cheapest spot welders after some severe vibration. To make it fair you would have to test all with thin nickel and low energy for equal ish comparison.
