Review on 🔀 ICQUANZX DC10 55V Forward Reverse Controller by Pedro Curtis

I originally ordered 4 of these controllers, two of which had no fans so I requested replacements which I received. In total I now have 7 such controllers, none of which work properly. I could get a refund for all of them if I had a chance to test them sooner and knew the ones with fans are bad too. I ran a test with a 450w 25vdc brushed motor and two 12v batteries in series. I have tested two without fans and they work correctly, 5 with fans do not. Two fanless fans can be controlled in the forward or reverse position with a "throttle" potentiometer with a forward/reverse switch. The ones with fans won't work unless you turn on the power while the forward/reverse switch is in neutral. You then have to preset the speed with the "throttle" potentiometer and use the forward/reverse switch to work, which is far from ideal. When power is applied through the forward/reverse switch in either forward or reverse mode, nothing happens. Neither the fans nor the motor work, nothing but the LEDs do not light up. Then when you turn off the power, put the forward/reverse switch to neutral, connect the batteries, the fan will start working immediately, and you can choose the forward or reverse direction, then you can control the motor speed. If you disconnect the batteries or turn the controller off with the "throttle" and then turn it back on, it won't work until you turn it off and select neutral and start over.
