THESE CELLS HAVE ALL BEEN VOLTAGE TESTED AND INSPECTED TO BE IN PERFECT WORKING CONDITION AND HAVE ALL BEEN REMOVED FROM WORKING MODULES. WE HAVE TESTED THOUSANDS OF CELLS OUT OF THESE MODULES AND WE HAVE BEEN AVERAGING AROUND 90-95% CAPACITY. WE GUARANTEE NO DEAD CELLS AND AT THIS PRICE YOU CAN'T GO WRONG.
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. LIFEPO4 ARE THE BEST OPTION FOR 12V BATTERIES BECAUSE 4 IN SERIES IS EQUIVALENT VOLTAGE TO A LEAD ACID BATTERY. WHICH MEANS RV, EV, COMPETITION AUDIO LOOK NO FURTHER. MOST OF YOU WILL MAKE CUSTOM BARS FOR THESE, AND SOME WILL USE THICK GAUGE WIRE OR WELDING. JUST KEEP IN MIND HOW MUCH POWER THESE THINGS ARE CAPABLE OF AND USE THE PROPER THICKNESS TO CARRY THAT POWER FOR WHATEVER YOUR APPLICATION WILL BE PULLING FROM THESE. THESE ARE 40 TIMES MORE POWERFUL THAN MOST 18650 BATTERIES. CHECK OUT THE SPECS BELOW, THESE ARE REAL SPECS.
