PWM DC Motor Speed Controller, DC 10-55V/60A, LED Display Stepless DC Motor Speed Controller with Adjustable Potentiometer and Forward-Brake-Reverse Switch

Had another one of these on my kayak for 5 years and wanted to upgrade all my wiring, so bought this new one. Am hoping to get the same years of service out of this one.

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

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

The media could not be loaded.  First off- Customer service is indeed excellent, though a little slow. This unit does run hot so if you plan to use it on a kayak, canoe or other boat and would like to put it in a waterproof housing it is not ideal. I put mine in a waterproof box and ran it for 45 minutes or so on a 21℃/70℉ day. Mostly at 100% but also varied between 25-45% and the air around the unit went up to 52℃/126℉. I also bought a battery monitor that has a thermometer, I highly recommend it- https://www.amazon.com/gp/product/B07759SLYP ) They responded that the highest temp this unit can tolerate is 70℃/158℉ but recommend keeping it below 65℃/149℉. They actually recommended another unit of theirs (https://www.amazon.com/gp/product/B0B5MMQKJY) for less heat. I have not used that yet. The idea is to get a controller with much higher amp/watt ratings than you need and heat will be less of a problem. A fan in a watertight box does nothing so don't bother unless adding holes. The MK Traxxis controller is another good option with supposedly no heat issues but $$$ (Video shows test at 25%, very little heat generated at lower %. Big temp difference when going to 100%)

easy to install, works well so far, seems well constructed
