A123 12.8v 150ah 1.92kWh Lifepo4 Battery - $125/kWh

These batteries have never been used and come in the original box. They are overstock and the stickers show they are from 12/2018. They still test full capacity, are balanced, and are resting at 13.17v. Just need to add a 4s lifepo4 BMS. Busbars can handle up to 150a.

Weight is 36.5 lbs
Dimensions are approximately 9" Wide x 6" Deep x 12" Tall

This battery would be very easy to add a BMS. Since they are all the same exact voltage and balanced you can series these as well.

1 module 4s (12v) = 12.8v 150ah 1.92kWh
