20 PACK - 3.7V 4.4ah 16.28WH W/ BMS NO WIRES

Regular price $23.00 $0.00 Unit price per

COMES OUT TO JUST $70/kWh! You get 20 cells for just $23.00

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

YOU WILL HAVE TO SOLDER YOUR OWN WIRES TO THE BMS ON THESE PACKS WHICH ONLY TAKES A FEW SECONDS. FOR SOME REASON THE COMPANY REMOVED THE WIRES ON SOME PACKS BEFORE SENDING THEM, SO MOST OF THESE HAVE THE WIRING HARNESS, YOU JUST HAVE TO RECONNECT ONE OR TWO WIRES. IF YOU WANT THE ONES WITH ALL THE WIRES IN TACT WE ALSO HAVE THEM HERE FOR AN EXTRA 15 CENTS PER PACK.

THESE ARE GREAT LITTLE PACKS, PERFECT FOR DIY PROJECTS. THEY CAME OUT OF GETAC SCANNING DEVICES. WE TESTED OVER 10000 OF THESE, BUILT MANY PROJECTS WITH THEM, 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 SCANNERS THAT WERE "UPGRADED" AND ONLY IN SERVICE FOR 18 MONTHS. SO THESE BATTERIES PROBABLY ONLY SAW LESS THAN 20 CYCLES.

EACH PACK IS BASICALLY 2x 2200mah CELLS IN PARALLEL, EACH WITH THEIR OWN 2A BMS. WE TESTED THESE PACKS AT 4A CONTINUOUS SO THE BMS SHOULD BE A 4A BMS ON THERE.

POSITIVE WIRES ARE CONNECTED TO THE SAME POSITIVE BMS TERMINAL AND THE NEGATIVE 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"

IF YOU DON'T GET ANY VOLTAGE READING JUST APPLY SOME POWER AND YOU WILL IMMEDIATELY GAIN A VOLTAGE READING, SOME PACKS THE CELLS ARE DISCHARGED DOWN TO 2.8V AND THE BMS IS PROTECTING FROM OVER DISCHARGE. JUST APPLY A CHARGE AND YOU ARE ALL SET. ALSO SOME PACKS THE BLACK WRAPPER IS PEELING. YOU CAN USE KAPTON, SHRINK, OR ELECTRICAL TAPE. IF YOU BUILD A PACK WITH THESE YOU WILL BE VERY HAPPY WITH THE QUALITY AND ENERGY DENSITY. THESE TRULY ARE GREAT CELLS AND THE POUCH STYLE IS THE WAY TO GO WITH NO LOSS OF SPACE IN BETWEEN CELLS. 

THE PHOTOS IN THIS LISTING SHOW WHERE YOU CAN SOLDER YOUR WIRES TO. THE CELLS ARE STILL CONNECTED, JUST THE LITTLE LEAD WIRES HAVE BEEN REMOVED. i WOULD USE SOME 22 GAUGE WIRE AND SOLDER THEM TO A BUSBAR AND BUILD SOME SOLID BRICKS OF POWER. 

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