Battery Box Welding Complete

I have finally completed the battery box welding. It was a much larger job than I anticipated but so far I am happy with the results. My welds are by no means professional looking but I did seem to have good penetration of the metal with my beads. There are a total of four battery boxes on my truck. One in the front (4), Two down the drive shaft under the bed (2X4), and one larger one under the bed behind the rear axle (6). The truck will have a total of 18 batteries in these boxes for my 144 volt system.

I will now be fabricating some wooden boxes to go within these metal supports.
