SPIM08HP 3.7v 8ah 200a LITHIUM ION W/ CELL HOLDER
HERE ARE POWERFUL SPIM08HP LITHIUM ION 3.7V 8AH CELLS THAT ARE RATED FOR 2000 CYCLES! (VIDEOS BELOW) THESE ARE BIG CELLS WITH A CRAZY AMOUNT OF POWER. EACH CELL WILL COME IN THE ORIGINAL CELL HOLDER! IF YOU WANT THESE IN PAIRS WITH THE THREADED INSERT WE ALSO HAVE THEM AS 16AH MODULES BUT IF YOU WANT TO MAKE YOUR OWN CONNECTIONS THIS IS THE CHEAPEST OPTION FOR THE CELLS AND THE HOLDERS.
EACH CELL IS RATED AT 200A DISCHARGE AND CAN BE CHARGED AT 80A. WE LITERALLY STARTED A CAR WITH 4 OF THESE IN SERIES.
PLEASE BE CAREFUL WITH THESE AND DO YOUR RESEARCH. THIS IS A MASSIVE AMOUNT OF POWER. WE TESTED 1000's OF THESE AND ON AVERAGE THESE ARE AROUND 95% CAPACITY. THESE CELLS WERE ONLY USED AS BACKUP POWER FOR COLD CLIMATE GENERATORS SO THEY HAVE NOT CYCLED TOO MANY TIMES. EVERY CELL IS CONFIRMED TO HAVE VOLTAGE SO YOU WILL NOT GET ANY DEAD CELLS.
IF YOU ARE LOOKING TO POWER SOMETHING THAT REQUIRES A LOT OF POWER IN A SMALL SPACE THEN LOOK NO FURTHER. THE TABS CAN BE WELDED WITHOUT HEATING OR DAMAGING THE BATTERIES OR YOU CAN CONNECT THEM WITH NUTS AND BOLTS OR RIVETS. ALSO THESE ARE MORE SAFE THAN 18650 CELLS BECAUSE WHEN THEY ARE SPENT THE BAG EXPANDS.
JUST KEEP IN MIND HOW MUCH POWER THESE THINGS ARE CAPABLE OF AND USE THE PROPER THICKNESS IN WIRE OR BUSBARS TO CARRY THAT POWER FOR WHATEVER YOUR APPLICATION WILL BE PULLING FROM THESE. THESE ARE 40 TIMES MORE POWERFUL THAN MOST 18650 BATTERIES.

The other photos show you some ideas on how these should be connected. Drop in a square dowel with threads or bolts lined up where the tab cutouts are. You would have to make those pieces. Or just find small screws with large heads and just lay a piece of wood in between and screw the tabs down tight but not too far so the screw doesn't hit the pouch.
