WHO NEEDS CELL LEVEL FUSING WHEN EVERY CELL HAS A BMS AND A TEMPERATURE SENSOR? COMES OUT TO UNDER $78/kWh!

THESE ARE GREAT LITTLE PACKS, PERFECT FOR DIY PROJECTS. WE TESTED OVER 100 OF THESE AND THEY TESTED AROUND 95% ON AVERAGE. THIS IS A PERFECT EXAMPLE OF HOW TECHNOLOGY MOVES FASTER THAN THE BATTERIES DEGRADE. THESE CAME OUT OF UNITS THAT WERE "UPGRADED" OR OVERSTOCK AND ONLY IN SERVICE FOR A FEW MONTHS. SO THESE BATTERIES PROBABLY ONLY SAW A CYCLE OR TWO.

WE TESTED THESE PACKS AT 2A CONTINUOUS FOR A FULL DISCHARGE SO YOU CAN CERTAINLY DISCHARGE AT A .4C RATE.

THE RED WIREs ON THE ONE END AND THE BLACK WIREs ON THE OTHER END WILL ALLOW FOR CHARGING AND DISCHARGING. NO NEED FOR THE CENTER 2 WIRES. EASILY BUILD A BATTERY PACK BY SOLDERING OR USING SPLICE CONNECTORS. CHARGE UP EACH BATTERY, CONNECT THEM IN SERIES OR EVEN PARALLEL THEM BY SOLDERING THEM TO A COPPER FLAT BAR. THIS WILL MAKE A VERY LONG LASTING, ENERGY DENSE BATTERY PACK WITH SUPER SAFETY FEATURES BUILT IN. NO WASTED DIAMOND SPACE LIKE YOU GET WITH CYLINDRICAL CELLS.

EACH BATTERY WEIGHS 2 OUNCES. MEASURES APPROXIMATELY 2.2" x 2.2" x .5" AND YOU GET AROUND 1" OF WIRE LENGTH TO WORK WITH. THE CONNECTOR IS A 6 PIN MICRO CONNECTOR. IT APPEARS TO BE A JST CONNECTOR BUT I'M NOT CERTAIN. MY RECOMMENDATION IS TO CUT ONE WIRE AT A TIME NEAR THE CONNECTOR. TRIM THE 2 CENTER WIRES ALL THE WAY DOWN SINCE YOU DON'T NEED THEM. EXPOSE AROUND A QUARTER INCH OF THE MAIN POSITIVE AND NEGATIVE WIRES. OR SIMPLY HOLD THE WIRES TIGHT NEAR THE CONNECTOR THEN PULL THE CONNECTOR OFF WITH FORCE. USE A FLAT NEEDLE NOSE PLIERS WITH SOME ELECTRICAL TAPE ON IT TO PREVENT A SHORT THEN PULL OFF THE CONNECTOR WITH A PAIR OF PLIERS. IT IS VERY EASY TO DO WHEN YOU GET THE HANG OF IT. USE SOME B-WIRE CONNECTORS TO MAKE SERIES CONNECTIONS OR TO PARALLEL WIRE THEM GRAB SOME COPPER PIPE, HAMMER IT FLAT, SOLDER YOUR CONNECTIONS TO THAT.

IF YOU BUILD A PACK WITH THESE YOU WILL QUICKLY DISCOVER WHAT A GREAT VALUE THIS IS. IF YOU HAVE ANY CELLS THAT DON'T READ VOLTAGE AT THE CONNECTOR JUST APPLY 4V TO WAKE THEM UP. SOME BATTERIES WILL BE RESTING AT 2.8V WHICH IS WHERE THE DISCHARGE CUTOFF IS SET ON THE BMS. THOSE BATTERIES WILL WAKE UP AS SOON AS YOU APPLY VOLTAGE TO THEM.
