Structure and inner electrical connection
A cell block comprises of 16 respectively 12 lithium-ion batteries connected in series. The battery cells are pressed together with pressure plates. 2 temperature sensors are also installed in the cell block. A lid is used for touch protection.
NOTE:
I12: The cell blocks are arranged in 2 rows one above the other. Observe repair instructions.
