Oh man. When I had my DIY E-skateboard, it was great fun to play around with that thing. Great vehicle for me to go to school and back.
Problem is I kept having electrical noise issues that caused my wireless to cut out. I never figured out how to reproduce it in the lab because it only seemed to happen under certain circumstances (possibly correlated to extremely heavy load, but not always). It caused some dangerous moments...
My build used a VESC X (from enertion skateboards, but seems like it was discontinued). The VESC is a nice open source high current motor controller, except the FETs they use are in a pretty dumb package, and the VESC X used an aluminum enclosure that acted as a heatsink for the DirectFETs they used.
I also used 2x 4S batteries[1] used for scale cars, because they had an integral plastic box that stopped it from getting pelted by rocks and such (good thing I got it, because I originally mounted it using Velcro and it fucking dropped during a ride and the battery slid for like 100 feet; probably would have exploded without the plastic box).
