Regular price $9.00 $0.00 Unit price per

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 AS BALLS FOR JUST 50 CENTS PER CELL PLUS JUST $3 FOR THE BALANCER. IT IS POSSIBLE ALL CELLS WILL CHARGE AND WORK BUT IT IS ALSO POSSIBLE THAT SOME CELLS WILL NOT BE GOOD.  FOR $9 YOU GET 12 K2 LFP26650EV 3200MAH CELLS IN 4S3P, A NICE ENCLOSURE, AND THE PCB BOARD IN THIS MODEL IS ACTUALLY A BALANCER. PHOTOS 3, 4, AND 5 SHOW THE BALANCER. IT IS A NICE PIECE YOU CAN ADD TO ANOTHER 12V PROJECT.

THIS MODEL DOES NOT HAVE A BMS, THE PCB IS JUST A BALANCER AND A CIRCUIT TO CONNECT THE MAIN POSITIVE AND NEGATIVE FROM THE CELLS TO THE CONNECTORS ON THE ENCLOSURE. I KNOW WHAT YOU'RE THINKING, THAT'S A CRAPPY DESIGNED BATTERY WITHOUT A BMS, AND YOU'RE ABSOLUTELY RIGHT. THIS COMPANY SHOULD HAVE HAD A BMS BUT I GUESS THEY ARE CONFIDENT ENOUGH IN THE SAFETY OF THE K2 LIFEPO4 CELLS THAT THEY FIGURED IT WASN'T NECESSARY. THESE WERE USED IN EMERGENCY BACKUP LIGHTING FIXTURES.

CELL SPECS ARE BELOW AND THE DATASHEET IS IN THE 2ND PHOTO FOR THE CELLS AS WELL.
