This is a Li-NMC battery out of a BMW Active E.  There are 96 cells in series making a nominal 355.2 Volt battery, at 80 Amp hours.  This comes out to 28,416 Wh, or about 28.4 kWh of capacity.  It arrived in a crate in three modules.  The crate weighed 1300 pounds. 

This battery was from Battery Hookup. However, it is currently out of stock. Here is a link to my current favorite battery available from Battery Hookup: https://batteryhookup.com/products/k2...
