PWM DC Motor Speed Controller, DC 10-55V / Rated 40A / Max 60A LED Display Stepless DC Motor Controller with Adjustable Potentiometer & LED Display Screen & Forward-Brake-Reverse Switch

FWD REV switch failed second use . i can still get motor to go FWD but not reverse . Not sure if it's a controller problem or the switch that went bad . for now i'll live with the FWD only but will end up replacing this with a better motor controller .don't want to buy just a switch if the problem is the controller. Edited to note that seller is stepping up and sending a new controller . I't good to know they will reach out after the return date and give a solution

Smooth Speed Control for a Power Wheels UpgradeUsed this PWM DC motor speed controller along with the DeWALT battery adapter to upgrade my grandson’s Power Wheels, and it works exactly as I hoped. It lets me dial in the speed so the extra power from the 20V battery doesn’t turn the car into a rocket, giving a nice smooth takeoff instead of a hard jerk. The knob makes it easy to fine‑tune top speed for different ages or surfaces, and once set it holds that setting reliably. Wiring was straightforward for a basic 12V system, and everything has been running cool and consistent. For projects where you’re adding more power and want control and safety, this is a solid 5‑star add‑on.

I purchased two of this item to wire a 12v Watersnake tolling motor to my Hobie kayak. First one got fried while wiring. I thought I wired it wrong. The second one got fried while testing on the water 3rd time. Each test was about 30 minutes run on and off. The third/last test was about 30 seconds. I turned it on to 1/2 - 3/4 of the max power. It just stopped working after about 30 seconds. Very disappointing. Anyone looking for my kind of set up, Watersnake t24 to Hobie kayak, don't buy this one.

We have purchased three different DC controllers for this project. The first two were from China and rated at 30 amps. They both got very hot and failed at 10 amps. We subseuently purchased this controller, which was more sophisticated and had nice remote controls and a speed or percent power indicator. This one is rated at 40 amps, whereas our application required 12 amps, so we intended to run it at about 30% or rated output. At 12 amps, this one also got hot but didnot burn out. We reduced the running amperage to 10 amps and the device did not reach a failure temperature level. We will build this unit into our product but reduce the rating to maximum of 15 amps rather than the published 40 amps. The controls and indicator are very well done.

Works great. You have to wire it with good components to have it last a few seasons on a boat.

Great product for the money

Using it on an old Minn Kota 30 pound. Working like a charm

Only worked for a very short time then quit

switch failed, came apart after very little use

These are so much cheaper than expected and works just like the expensive ones.
