40MPH DIY Electric Skateboard

Good morning ladies and sirs. This esk8 (Night Hawk) is the fastest build that came out of my garage. Top speed of 40mph or 64kph. Here is the set up that makes 40mph happen:

Pulleys and Belts: 5M20T Motor Pulley, 5M42T Wheel Pulley, Belt 5M15MM 295

Deck: I build it from plywood, fiberglass, and epoxy. Deck vid available here: https://www.youtube.com/watch?v=BgwRVQ6lTJo

Battery: 12s4P12Ah made by me. To make series connection, I used 1 layer of 10mmx0.15mm nickel strip+12g pure copper wire soldered on top of nickel. 18650 cell is LitoKala HG2 (they have been working reliably for me in multiple builds).

Motor mounts did not fit trucks exactly. I had to alter them a bit. It was an easy alteration though:
