Does the job
I got this for my sons little electric tractor. I put a 18v drill battery on a 6v electric tractor. I burnt the first motor out soo got this to hopefully save the motor. 1 year in and its still going strong 💪

Works
I used this to reduce the voltage on a Power Wheels that now operates on a Dewalt 20V Max battery. The board appears to be relatively simple. I am not an experienced electrical technician, but the one feature I would have liked to see was some indication on the dial as to what voltage was being given. In lieu of this, I placed an LCD voltage monitor on the output side and can now monitor the voltage being sent to the motor, but it’s essentially useless as the meter will show high spikes of voltage and then drop, which I suspect is the result of the use of the lithium ion batteries. Nonetheless, when the dial is too low, the motor will not turn, and an adjustment of the dial will adjust in over-voltage, so this piece certainly does work.

This thing is a BEAST!! I go over it's rated specs and it still works perfectly.
I've pushed this one really hard testing it ... Once my setup stopped and I thought this had broken but in the end it was some WIRING issue that caused the problem. It's a beast - if you're powering a BRUSHED motor this is a fantastic ESC for it. And I mean ANY portable motor - I use this for DC 775, 895 and 890 motors at full speed, and over voltage. I don't think bigger handheld motors exist. I can run it 30 Volts / 10 amps flowing from the power supply, nonstop for hours at a time and the motor needs servicing when this does not. Well done folks!

Works good
Works good, speed control knob spins kind of easy on bumps is my only complaint.

Seems to hold up
Bought this for my son's power wheels after the stock board got cooked. It took me a little while to figure out the correct way to wire everything up, it seems to be working good but it's gone through a few 30amp Fuses when turned all the way up

It does its job correctly
Very well made, just a warning. The voltage does go up when not powering the load. Meaning that you can bun stuff if you don't have the load on when turning power on. This is expected however I was not aware.
