Lower battery tray, still need to file and sand it.
Test fit the battery tray.
Here is a rough cut of the battery tray and strap
The battery tray assembled
The only problem I might have later is the battery strap not being strong enough. Right now it works great, but as I tighten the wing nuts the strap start to arch. I think I should have made the battery strap a little thicker. Until it breaks I will leave it as is.
