This is my battery and electronics enclosure for my electric skateboard. I hope there are someone out there that can use my design as Im quite happy about it.

Lithium cells: Turnigy 5000mAh. 12 cells total. See picture.
ESC: Alien 120A 12S
Oval Switch can be found on eBay. (I bought mine on Biltema). Search for "30A car switch".

I mounted the enclosure to the board using flexible glue. It will fill the cracs between the board and handle the movements well when the board flexes.

See the drawing in downloads.

Good luck!
