After this happened I knew it was time for one of your trays Mike.
47mmX158mm is the dimensions of the battery so I need a 47mmX160mm battery tray right? That's inside dimensions right? The tricky part is how it will be mounted. I need some tabs or a shelf or two that can be trimmed down and drilled for screw holes just like this:

Thats 3 mounting locations. Ignore that post in the rear, its not connected to the chassis just the carbon fiber sheet/tray used like this:

Here is the new battery that needs the tray:

Its a Hyperion 35c 4s 6500mah.
Here is the rest of the truck
Mike can you do this for me. Do you need more measurements? Can I use a tray already in stock?
Thanks,
Zack
