This highly spec’d controller is used to run the Smart & Grunt motors, and can also be used to up-power almost any mini-motor kit on the market.
The Magic Controller has functionality to control a throttle, cruise control, electric horn, electric lights, brake cut-out / regen function, pedelec device, and even reverse function (for those of us who are a little backwards!). It can run multi-voltages (24v, 36v or 48v), at up to 30amp continuous and 50amp peak, and various parameters are fully adjustable with the controller software. The USB Programming Cable to do this is available on request, for additional $50.
You can set the current, the speed, the acceleration, and the braking strength using the software, which many people find useful.
