Exhausted

I got two 12x12 sheets of 22ga (they did not have 20 and I couldn't find anything between 22 and 16) and two heavy duty velcro straps. I also got some p-clamps that I think will help mount the electronics box to the frame.
 
Mission accomplished and I only used the one 12x12 sheet. The jigsaw worked fine but it vibrated a lot. The ghetto sheet metal brake also worked.

I was on the right track last night. I just didn't think it through and didn't take my time and I think the metal I was using was a little flimsy. This time I thought the design out and measured twice.

The battery will be strapped to the "U" shaped support in front of the rear shocks. The "box" will be bolted to the "U" around the battery on the underside to prevent sliding. The heavy lifting will be by the strap but the box will keep everything in the right spot.

Thanks for the help!

Ghetto sheet metal brake... Excuse me..

That's my "low investment tooling" you're talking about there. :)
If you don't have either the cash or the need for a tool you have to get clever. I was taught that by someone whose almost as tight with cash as I am.

You can learn a lot just by trying things - as long as you are patient and careful. Glad to hear it worked for you. make sure the components are secure and insulated from vibration and you should be in good shape.

What you also just learned is that strength and rigidity in metal components comes primarily from shape and not from thickness. Too thin and it's flimsy and will fail through fatigue but so often people make brackets and mounts that are 3-5 times thicker than they need to be. Use a 3D shape to provide strength rather than thickness.

Exactly, this goes for other materials as well. The strength of composite materials is in the curves. Flat piece of fiberglass isn't very strong but put a few curves in there and its a much different beast.
 
Glad you are making progress, BUT, don't kick yourself for walking away and working on another project. I am always in a hurry to get crap done, but in my older age I have found that when I walk away, I tend to come up with ideas when I least expect it, and often when working on something else.

Not sure if this is of any help, but just another idea (about half way down the first page):
