Battery Boxes Completed

The battery boxes and motor mount are complete. It took 3 solid days welding and grinding then 2 days painting. Another few hours putting them into the car and I am ready to start wiring. The rear box just fits under the rear seat with about 5mm clearance and the batteries can be maintained by removing the seat (4 bolts) from above. The front box holds 20 batteries and is mounted across the engine bay. The controller contactor and fuse is mounted in front of the batteries on an aluminium plate.

I've mounted some sealed ABS cases for the contactors, fuses and BMS slave boards and run the battery cabling from the rear battery box to the engine compartment in "flexible" orange underground conduit. That stuff is not very flexible and it was a painful experience.

Replaced the bonnet and closed it to see if the battery box fitted. There is only about 2 mm clearance in one spot so I will be doing a small amount of panel beating under the bonnet to give a bit more clearance.

Next weekend more wiring.
