THESE CELLS ARE BRAND NEW IN THE ORIGINAL BOXES. YOU GET 8 IN A BOX FOR EACH ORDER AS SHOWN IN THE PHOTOS. ALL THE BOXES WE OPENED HAVE PRODUCTION DATES OF 7/24/24 SO THEY SHOULD ALL BE NEAR THAT DATE RANGE.
COMES OUT TO JUST $11/CELL.
THIS IS THE MOST POPULAR CELL FOR CAR AUDIO AND PERFECT FOR ANY APPLICATION THAT REQUIRES HIGH POWER IN A SMALL SPACE. MANY CUSTOMERS MAKE THEIR OWN BUSBARS AND ACCESSORIES BUT WE DO HAVE CELL HOLDERS, BOLTS, AND 100A BUSBARS AVAILABLE AT A GREAT PRICE IF YOU NEED THEM. WE ALSO HAVE BMS UNITS AS WELL. DEPENDING ON THE THICKNESS OF YOUR BUSBARS THE LENGTH OF THE BOLTS YOU'LL NEED WILL CHANGE BUT THE BOLT SIZE YOU NEED IS A VERY COMMON SIZE M6-1.0. WE HAVE THE 8MM SIZE AVAILABLE WHICH IS GREAT FOR BUSBARS UP TO 1/8" THICK. IF YOU PLAN ON MAKING THICKER BUSBARS YOU WANT TO ORDER BOLTS THAT ARE ABOUT 1/4" LONGER THAN THE THICKNESS OF THE BUSBAR.
THESE ARE BIG CELLS WITH A CRAZY AMOUNT OF POWER. EACH CELL IS RATED UP TO 120A CONTINUOUS DISCHARGE (15C) OR 240A PULSE (30C) AND CAN BE CHARGED AT 80A CONTINUOUS (10C). YOU CAN START A CAR WITH 4 OF THESE IN SERIES. PLEASE BE CAREFUL WITH THESE AND DO YOUR RESEARCH. THIS IS A MASSIVE AMOUNT OF POWER.

Calculate Your Battery Pack
If you over tighten your bolts it could damage the cell. If you have a torque wrench set it to 3nm. Do not tighten over 4nm. We are not responsible for user error. Every cell is factory tested and in new condition. If you over charge/discharge, over torque the connections, or cause a short we will not replace the cells once they are handled and assembled into a pack. Always use a BMS, cell holders or insulation between the cells, proper size busbars to carry the current, stay within the voltage/amps of the cells, and take necessary safety precautions.
