DISCHARGED - K2 3.2v 90ah K2B3V90EG Lifepo4 Power module
THESE MODULES IN PARTICULAR HAVE BEEN DISCHARGED WHICH IS WHY THEY ARE ONLY $10. THEY WILL TAKE A CHARGE BUT YOU WILL NEED TO SLOWLY CYCLE THEM A FEW TIMES TO GET THEM TO HOPEFULLY RECOVER. MANY CUSTOMERS HAVE HAD SUCCESS WAKING UP THESE BUT IT IS LIKELY THAT SOME BATTERIES WILL SELF DISCHARGE. THESE HAVE NOT BEEN SITTING AT 0V FOR LONG.
If you are a car audio enthusiast you may recognize these batteries from a popular brand. These cost almost $400 per battery from them. These are one of the best Lifepo4 batteries out there and they are trusted by the US military. These batteries were overstock from a larger military project in which the company decided to discharge this particular batch before sending them to us. We include the bolts too. Check out the amazing specs in the 3rd photo. These batteries can discharge at 300 amps continuous and pulse at 700 amps. For car audio these are probably one of the best lifepo4 options. I wish we had more.
THESE ARE NOT PRISMATIC BATTERIES, THEY ARE MUCH BETTER. CHECK OUT THE 3RD PHOTO. AS YOU CAN SEE THEY ARE MADE UP OF CYLINDRICAL CELLS WHICH WILL GET MUCH BETTER PERFORMANCE AND CYCLE LIFE. THESE ARE BUILT LIKE TANKS. THEY USE 28 K2 LFP26650EV CELLS. EACH CELL CAN PUSH 28 AMPS FOR 30 SECONDS. 28 AMPS x 28 CELLS = 784 AMPS. THAT'S HOW THEY GET THEIR 700A PULSE RATING. THESE CELLS ARE RATED FOR OVER 2000 CYCLES SO YOU KNOW THIS PACK WILL LAST A LONG TIME IF YOU CAN GET THEM TO RECOVER. WE DID APPLY VOLTAGE TO MAKE SURE THEY TAKE A CHARGE SO YOU WILL NOT GET ANY INTERNAL SHORTED BATTERIES. THEY WILL TAKE A CHARGE AGAIN, CAPACITY AND SELF DISCHARGE IS UNKNOWN BUT MOST CUSTOMERS HAVE A GOOD PERCENTAGE OF SUCCESS WITH THIS.
