tatoko DC Motor Speed Controller 10V-55V 12V 24V 36V 40A Stepless DC Motor Speed Controller with Forward-Brake-Reverse Switch,Ajustable Potentiometer &Digital Display

The media could not be loaded.  Installed as part of a modification on a ride-in car for a very cautious 2.5 year old. This single speed 4WD jeep in stock condition was too fast for the student driver. I also added the capability to run the motors on 20V lithium drill batteries, using some relays and a "buck converter" (actually 18 bucks on Amazon) to reduce the voltage to 12V going to the stock controller box to avoid blowing out the radio and lights. I fantasize about using my 56V E-Go battery packs some day, so I chose a converter rated for up to 60V input (https://www.amazon.com/gp/product/B08HS19W8Z/ref=ppx_yo_dt_b_asin_title_o02_s00?ie=UTF8&psc=1 ). The Tatoko hardware is well-built and solid. The output varies smoothly with the control knob (as judged by motor speed). The duty cycle indicator corresponds well to the average output voltage as measured by a multimeter; 70% duty cycle on 20V input batteries provides 14V output. This controller has a Forward-Brake-Reverse (F-B-R) rocker switch, which I believe is pretty much required for this type of application, since my understanding is that you cannot reverse the Input polarity on a PWM controller, so you will be replacing the stock F-B-R in the dash with the one provided with this controller. No extended tests, but the controller worked perfectly with me riding on the vehicle. Highly recommended. Some nits to pick with installation: It would be helpful to provide a packet of mounting screws and maybe a little paper template to locate mounting holes. Most garage mechanics won't have tiny metric screws lying around unless they've also worked on computers and electronics. The duty cycle indicator has no provisions for mounting. If you search for the part number, you can see that similar indicators are available with little mounting tabs. I marked and carefully cut the rectangular outline, taped it in place temporarily from the front, and used hot melt glue to secure it from the back. The rocker switch is smaller than the ones used on kids toys, so I needed to fabricate a plate to replace the stock F-B-R switch in the dash. The wire leads are also fairly short, providing limited mounting options. It would have been preferable to be able to mount the unit in the battery and controller compartment with wire leads running to the dash, as opposed to mounting the entire unit with short leads to the back of the dash. Finally, PWM controllers work by "chopping up" the DC output into a series of pulses. My multimeter read the average voltage, but the dash voltmeter flickers uncontrollably below about 70% duty cycle. It would be a nice feature to include a noise-free voltage output.

I received this beginning of april. It worked initially with a small load of 12v at 2 amps. Very small. After a few months with absolutely zero use (I bought it for a side project I only am now starting) it has completely died.Long story short, without any use this part has completely died and will not take any load.I'd probably look elsewhere for more reliability.

Yes

Easy installation

I purchased two different units with very similar results . The First first one lasted 15 minutes and second one lasted 10 minutes. Motor only draws 10 amps and the controller keeps blowing mofsets. This controller is complete waste of money and especially time. Seller is nonresponsive. They know they’re selling a product that doesn’t actually meet their description. Save your time and money and purchase a different unit. 12v relays in something that’s supposed to be rated up to 55v
