36v A123 2300MAH LIFEPO4 CELLS ANR26650M1A IN 12s8p CONFIG
These are a great, cheap source for 26650 LifePo4 A123 cells. The packs are used, balanced, and in 36v 12s8p configuration. They are built solid, used for city bus applications so they may be a little dirty. The modules are roughly 50-70% 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.
Photo #2 shows the professional 0.2c discharge test we performed. We broke the 12s8p module down to 3x 4s8p 12v packs and ran some spot tests on the modules. The test shown was the lowest capacity out of the tests we ran. 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.
