After the two battery boxes were welded, some parts were still missing inside. We needed to add stabilisation tubes, through which the main suspension screws will go. Roman helped us welding the tubes to the boxes. Thanks a lot! Afterwards they were sealed with Sika to prevent water from running into the boxes.

Another action was to rasp the holes into the back walls of the boxes which will carry the plugs for signal and power connectors. The signal connector will carry CAN-communication lines, supply power for the battery management and an interlock line. Sweet! The power connector takes two shielded power cables carrying upto 350 amps!
