It all stated with a box full of branded powerbanks nobody had any use for. So I started to take a look inside these powerbanks and found what I expeced: brand new useful 18650 cells! Each cell has a rated capacity of 2AH or 7.4Wh. Tests show that all of the cells had around 2AH capacity.

So I gathered some friends to help me disassemble and salvage all of the cells. We rescued 38 cells in total!
