Way better than the stock controller especially love the variable throttle. Does get a little warm but not too warm. Then I decided to upgrade the motor from 250watt to 350watt for more power and speed and controller takes that quite well too. Does get warmer than before but not hot at all. Please note that this 36v 800watt controller is NOT waterproof due to no silicone around it so make sure it's in a dry enclosure to prevent damage to the controller. Easy to wire up, Blue wire is positive to motor, yellow is negative to motor. Will buy again in future. ### ⭐⭐⭐⭐ Very versatile once you figure out the pinout. *by R***L on Reviewed in the United States on October 9, 2020* I used this controller to add proportional throttle to my kid's dynacraft 24v UTV vehicle. It took a little research to get it working but so far it's been great! There are no instructions included and all the labels are in Chinese. Thankfully, I was able to find an English pinout diagram for a similar unit on Google. That combined with a little reverse engineering allowed for a successful install. I used an electric ATV hall effect throttle peddle (red 5v, black GND, green 1-4V) for throttle control. I repurposed the original dynacraft accelerator peddle for a break peddle with one NO contact connected to the yellow and black break lead. It has two red/black lead for break lights. I used one to activate a relay that disconnects the motors from the controller and applies a break shunt. ### ⭐⭐⭐⭐⭐ Standardized plugs, drop in replacement *by P***N on Reviewed in the United States on August 26, 2019* I bought an electric quad and the controller broke within a day.No help or support from rosso motors. They just wanted me to buy a new controller at $70.At $13 this was amazing value.This does not support the three stage speed limiter that the one on the quad did, but other than that it was a simple replacement and the kids have been tearing up the dirt ever since. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.uk/products/106782610-a94-co](https://www.desertcart.co.uk/products/106782610-a94-co) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-05-26*
