These BMW batteries appear unused and are perfectly balanced however it is not confirmed they are unused. It's likely one of the mounting brackets or another component had an issue and the module couldn't be installed. They come in the original box too. They are made with Samsung lithium ion cells. Each cell is 3.7v 60ah 223wh. The cells say 223wh on them. There are 40 cells in 8s5p configuration.

Always use a BMS.

We are not sure what car this came out of. The modules arrived as shown in the original boxes. These are being sold for solar storage or some other use and not as a replacement module for a BMW vehicle.

Module fully charged voltage is 33.6v (4.2v per cell)
Module fully discharged voltage is 22.4v (2.8v per cell)
