UNDER 10V - 12v K2 battery 12.8v 9.6ah K2B12V10EB

THESE MODULES IN PARTICULAR CAME OUT OF MEDICAL APPLICATIONS. WE TESTED A LOT OF THEM AND THESE ARE THE UNITS THAT TESTED UNDER 10V SO WE ARE SELLING THEM CHEAP. IT IS POSSIBLE ALL CELLS WILL CHARGE AND WORK BUT IT IS ALSO POSSIBLE THAT SOME CELLS WILL NOT BE GOOD.  FOR $6 YOU GET 12 K2 LFP26650EV 3200MAH CELLS IN 4S3P, A NICE ENCLOSURE, AND THE BMS.

Most of these are mostly discharged but the cases look nice and perfect for reuse.
