Cells, No Holders SPIM08HP 3.7v 8ah
These are the batteries without the cell holders.
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 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 YOU CAN EXPECT ABOVE 90% CAPACITY. GUARANTEED NO DEAD CELLS.
IF YOU ARE LOOKING TO POWER SOMETHING THAT REQUIRES A LOT OF POWER IN A SMALL SPACE THEN LOOK NO FURTHER.
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.
THESE ARE BATTERIES WITHOUT THE CELL HOLDERS.

2nd photo shows how we connect these into 1s2p packs. 3/8" square dowel with 2 bolts threaded all the way through lined up to the tab cutouts. Bend the tabs over, tighten with a nut. Super easy. Some people use rivets, some use busbars and clamp them. Just don't let your connection overlap to the cell wrapper because the cell wrapper is slightly conductive.
