Review on High Performance Electric Brushless DC Motor Kit, 48V 2000W 4300RPM, with Controller and LCD Throttle - Perfect for Electric Scooters, Bicycles, and Motorcycles by Kaveen Reyes

I deducted one star mainly because they don't seem to provide any real documentation and people keep referring to their Revain list for training. I wasn't expecting much at this price but it works exactly as described. Wires have mating connectors except for powering motors or batteries. All connections have also been marked. Reverse seems to be 1/2 to 1/3 forward power on my build and I'm checking with the seller if that can be changed. I use it to drive a small internal propeller shaft on a sailboat.
