COMES OUT TO UNDER $100/kWh FOR BRAND NEW IN THE CASE BATTERIES WITH A BMS!

THESE ARE FULL UNOPENED CASES WITH 80 3.7V 4.4AH 16.28WH LITHIUM BATTERIES EACH WITH A BMS. THIS COULD BE THE GREATEST VALUE NEW CELLS WE EVER OFFERED. 

WHO NEEDS CELL LEVEL FUSING WHEN EVERY CELL HAS A BMS AND A TEMPERATURE SENSOR?

THESE ARE GREAT LITTLE PACKS, PERFECT FOR DIY PROJECTS. THEY WERE MEANT FOR GETAC SCANNING DEVICES BUT NEVER USED AND STILL IN THE ORIGINAL SHRINK WRAPPED PALLET.

EACH PACK IS BASICALLY 2x 2200mah CELLS IN PARALLEL, EACH WITH THEIR OWN 2A BMS. WE TESTED THESE PACKS AT 4A CONTINUOUS FOR A FULL DISCHARGE SO YOU CAN CERTAINLY DISCHARGE AT A 1C RATE.

THE TWO RED WIRES ARE CONNECTED TO THE SAME POSITIVE BMS TERMINAL AND THE TWO BLACK WIRES ARE ALSO CONNECTED TO THE SAME NEGATIVE TERMINAL ON THE BMS AS SHOWN IN THE PHOTOS. THE WHITE WIRE DOES NOTHING FOR US. 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. NO FUSES NEEDED! EACH BATTERY IS PROTECTED!

EACH BATTERY WEIGHS 3.1 OUNCES. MEASURES 3" x 2.25" x 3/8" AND YOU GET AROUND 2 INCHES OF WIRE LENGTH TO WORK WITH. THE CONNECTOR IS A 5 PIN CONNECTOR WHERE THE PINS ARE 2.0MM SPACED. 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 WHITE WIRE ALL THE WAY DOWN SINCE YOU DON'T NEED IT. EXPOSE AROUND A HALF INCH OF THE WIRE ON THE TWO BLACK AND TWO RED WIRES. TWIST THE TWO BLACK WIRES TOGETHER THEN TWIST THE 2 RED WIRES TOGETHER. THAT IS YOUR MAIN POSITIVE AND NEGATIVE. 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.

EACH CELL FULLY CHARGED IS 4.2V, FULLY DISCHARGED IS 2.8V. STANDARD LITHIUM ION CHARGE AND DISCHARGE LEVELS.
