Reclaiming 18V 18650 battery pack - part 1

Note: The electronics in these things commonly monitor the individual cells and for this one (from top) cells 2 & 5 are not being charged correctly. The batteries should come up OK with individual charging.


Cells 2 & 5 are reading very low. I have already charged cell 2 and it's come up to full voltage with current set to 350mA.


When this one is done I'll charge the whole pack at 18V with a current value yet to be determined.




Taking a break from pruning the Lemon tree to check progress.
Cell 5 which was reading about 1.5V is now. puling 340mA... looking good.
