3s2p Sanyo Module with 6 3500mah 18650 - Aluminum

Here are really nice Sanyo medical modules. These have 6x NCR18650GA 3500mah cells inside and are in 3s2p configuration. The greatest thing about medical batteries is they don't get cycled too many times before they get recycled so these cells you can expect pretty good capacity readings. Also medical batteries tend to use high grade PCB boards for those of you who like to scrap.

Its hard to find 3500mah cells so it's nice to find them in modules where the cells are likely to test great still. Just $1.50/cell for 3500mah cells. 

The BMS is likely proprietary so these would be for cell recovery and PCB scrap.
