Battery Boxes, part 3

The first 12 cells are mounted. It was a bigger chore than I expected avoiding all of the potential interference issues. The rear crossbar (the one with the clamp) will be welded in place once the second box is completed and mounted.

Here is a close up of the cross bar mount.

There is only 3/4 inches (19 mm) of clearance between the motor and the battery box.  If there is any rubbing I will switch to a stiffer racing style motor mount.

The cells are mounted below the rear motor mount bracket.

The box sticks out beneath the bottom bumper and valance. This is mostly a cosmetic issue, but if mounted too low, dragging could be an issue driving up the drive way. From most angles, they box is not visible, but if you are low enough, or far enough away, it will be visible under the rubber bumper. Painting the rack black should help it blend in.

A clearance issue with a curved part of the frame forces me to offset one of the mounting points.

One corner of the box is close to a tie down plate on the frame of the car.

The boxes were skinned with sheet metal.
