2 good cells - Battery Pack with 4 K2 LFP26650P cells
These battery packs were tested for voltage and these in particular had 2 cells with voltage and 2 cells with 0v. You are only paying for the 2 cells that has voltage and it is possible the other 2 cells will wake up and work again after cycling a few times but it is not guaranteed. Just $2 for 4 cells, 2 have voltage.
These battery packs were removed from service because some battery assembler built these without balance leads or a BMS. So these are just 4 cells in series.
Here are battery packs with 4 K2 LFP26650P cells. These packs are for salvaging the cells. These are super powerful cells. They can actually pulse up to 150a for 10 seconds. These packs are used and we are selling these cells dirt cheap. Not too many of these packs are available so get them while they last!
