CASE with 2x 36v A123 LIFEPO4 736wh Modules - 192 M1B cells!
You get 2 36v modules in the original case as you can see in the 2nd photo. These are used modules but perfectly balanced with the newer a123 26650 m1b version cells. 192 cells for just $1 each. These are true power lifepo4 cells. Each cell can push 120a for 10 seconds. 1 36v module is powerful enough to push a golf cart or forklift. These are one of the most powerful, well built modules out there. Cells are in 12s8p configuration.
These are a great, cheap source for 26650 LifePo4 A123 cells. These are the newer versions of these packs, not the older versions that are more degraded. They have the newer m1b cells inside instead of the older m1a cells. The packs are used, balanced, and in 36v 12s8p configuration. They are built solid, used for city bus applications. The modules are roughly 80% of original capacity but still plenty of useful life in them and priced accordingly. Built for serious power. You will need to add your own BMS, the BMS on here would be great for salvaging gold. Adding a BMS would be super easy because you can add ring terminals to your balance leads and screw them down to the balance nickel sheet like the original BMS is set up. The original BMS is used to communicate to a main system to trigger on and off so the included BMS does not function like a BMS for DIY use.
They can be broken down pretty easy to 4s 12v modules but the plastic housing took some time to pry off. The plastic housing does come off clean and works perfect if you want to reuse it for cell holders. Its just the plastic holes are sort of wedged in between the cells and you have to pry it off evenly to not break the cell holders.
Module fully discharged voltage is 30v (2.5v per cell)
