Review on L-faster 36V/48V 800W Electric Motor Controller: Optimal Brush DC Motor Speed Control ideal for Electric Tricycle, Scooter, and Brushed Controller by Blake Clemons

I used this controller to upgrade an old 20" Ev Global Ebike from 24v to 36v. Once you sorted out the wiring (good luck) everything worked fine. We rode at least a few hundred miles, maybe a thousand, from bike lanes in Northeast Florida, Clearwater, to the shores of Alabama Bay and everything we found between them, pedaling at a top speed of 22 mph. What has happened is that now if you run the engine over 3/4 throttle for more than a few seconds the controller cuts out. Unplug the battery and plug it back in, it immediately reboots and does the same thing. Everything burned out on me, so if the engine pulled hard, the fuse blew. Just ordered another one, $20 a year or two isn't that much. Now that I've hardwired it, as long as I'm using this controller, I can only switch wires one at a time, so it takes less than an hour to install. For $20 it's worth it. Honestly, if you use a brushed motor on an e-bike, that motor is getting old anyway and most people only ride their bikes occasionally, so why invest a ton of money in it? If this motor dies I will switch to brushless and that will require a new controller anyway. It costs $20.
