I am going to report my experience with the Yuneec E-Go.
I own two - one that is stock and the other runs on 10S + VESC + Stock motor.
10s will kill the stock ESC, you have been warned. The motor gets toasty on hills at 10s (low battery voltage @ 37V), so maybe not a good combo. I am...
You're in the right place.
What this PCB does is divert a small flow of power through a switch.
When activated, the switch opens the MOSFET transistor gates, allowing power to flow.
The bill of materials and PCB order pages are linked to this document. If you want a premade thing, I believe...
Your BLDC motor is sensored.
A sensored motor detects the magnetic fields generated by the coil to determine the optimal firing rate/power distribution to the coils. I suspect that Boosted uses Delta windings for speed, so you should expect to find a large number of cables going from the motor...
