I bought this for $19 thinking I'd be lucky if it even worked at all.
The controller is advertised as follows:
*)38A max.
*)36v or 48v operation.
*)Sine Wave output.
*)Supports both Sensor or Sensorless operation
*)Autodetection/configuration of motor direction AND hall sensor wires (just get +/ground right).
Usage.
Wire up three motor windings and battery (but dont connect yet) to controller.
Wire up "orange" wire to red power (orange wire would connect to "ignition" on/off switch).
.....optional: hook up motor hall sensor wires.
Connect the two green "motor autoconfiguration" wires together.
Connect the throttle.
Connect battery. Motor will start to turn....if turning wrong way, roll throttle and motor will change direction. Once turning right way, pull apart the two green wires. Controller will remember setting.

Findings:
Controller autodetects SENSORLESS motor....and remembers setting.
Controller also autodects SENSORED motor....and remembers setting.
Output is indeed Sine Wave! *****EDIT....is trapezoidal wave form....my bad]
36V cutoff OK....did not test w/48v pack....may try power supply in a few days dialed in at 48v?
Throttle is like a govenor whose RPM changes with throttle movement....RPM stays locked in when force is applied, amp-draw increases to maintain RPM.
Nice basic controller. Hope it holds up.
