ABOVE 10V - 12v K2 battery 12.8v 9.6ah K2B12V7ET

Regular price $12.00 $0.00 Unit price per

WE TESTED A LOT OF THESE MODULES AND THESE ARE THE UNITS THAT TESTED ABOVE 10V, MOST IN THE 12-13V RANGE SO YOU KNOW ALL THE CELLS WILL HAVE VOLTAGE AND BE ABLE TO GET REUSED. IT IS LIKELY THAT THE CELLS HAVE SOME DEGRADATION BUT THEY WERE ONLY USED AS BACKUP POWER SO THEY HAVEN'T SEEN TOO MANY CYCLES. FOR $12 YOU GET 12 K2 LFP26650EV 3200MAH CELLS IN 4S3P, A NICE ENCLOSURE, AND THE PCB BOARD.

THIS MODEL DOES NOT HAVE A BMS, THE PCB IS LITERALLY JUST 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, 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.
