Have a few old 12ah milwaukee battery packs for free. Its the cells only, i am reusing the original battery cases.
3 x went unbalanced. Instead of going thru the effort of balancing, I chose to just rebuild. So that's 45 samsung cells.
1 x Molicel p45b pack. This pack only has 14 usable cells. I spot welded where I should have soldered, causing a hot spot that melted part of the casing and damaged 1 cell.
