Used 43.8V 37Ah 1.62kWh NMC Pouch Module - Needs BMS

Here are genuine A123 Systems NMC pouch modules. These are 12S packs
using A123’s NMC cells. 

These came out of specialty/automotive applications and are built in a
solid metal case with structural ribs. They have large power terminals
on one end and a multi-wire sense harness on the other (you’ll need to
add your own BMS).

Every module has been checked and is sitting at good voltage.

Wiring is all there in the harness to be able to attach a BMS.

Great for 48V systems, EV conversions, solar storage, or tearing down
for the individual NMC pouches. The cells inside are high-energy NMC
pouches with solid power capability.
