$75 is an amazing price for a VESC 6 clone. Looks like it even has a basic anti-spark built in. No bluetooth or IMU.
Same mosfets & current amps as the early Trampa VESC 6s. Plastic housing and finned heatsink makes it hard to mount to an external heatsink. It could probably be replaced with a simple block of aluminum to make it work with an external heatsink.
Also the dual V4 is the cheapest VESC based dual motor controller I’ve seen at $88. Curious to see the nudes. If they used something other than the original 4.12 mosfets it might be decent.
