K2 3.2v 90ah K2B3V90EG Lifepo4 Power module
ONLY 1 LEFT
If you are a car audio enthusiast you may recognize these batteries from a popular brand. These cost almost $400 per battery from them, but we have some for just $95 per battery. 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, they have never been cycled and the test results are shown in the 2nd photo where it shows 89.91ah. We numbered some for testing so you may see some markings from our tests but these are in excellent, like new condition. 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 4TH 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.
