- 【Speed Control Knob】: The knob has a switch function, which can control the motor speed from 0% to 100%. Adjustable potentiometer flexible cable can be separated, the cable length is 15CM.
- 【30A Fuse】: This set contains a 30A fuse to prevent shorting of the motor interface. Double protection of your Motor and Motor Speed Controller.
- 【Note 1】: The power of the input power supply must be greater than 1.5 times the rated power of the motor to make the motor work (note: the input voltage and the rated voltage of the motor must be consistent).
- 【Note 2】: If there is a forward-reverse circuit regulator on the children's car, please be sure to connect the speed controller between the power supply and the forward -reverse circuit regulator of the children's car. Otherwise, the speed controller may be damaged.

## Questions & Answers

**Q: It worked at first, now it won’t limit speed. Just full speed. Any idea what’s wrong?**
A: Mine was like this out of the box. With the potentiometer fully closed to fully open I'm getting 19.4 to 19.99 V from a 20V power source. Totally useless. I'm going to return it and try to find a higher end alternative. This one looks and feels super cheap. If it worked, it would be a good value but clearly they have a lot of QC problems.

**Q: Why does the internal fuse keep popping with a 20V 5A dewalt battery swap in a powerwheels car?**
A: The DEWALT battery is most likely a 5AH which rating of length of power but a DEWALT battery will actually pop a 30A fuse on initial power surge. I just recently used one of these on my daughters power wheels and I ended up putting a 40A fusel in and haven’t had any issues so far

**Q: can this be used on a minn kota EDGE 45lb.thrust 5 speed trolling motor?**
A: If it's between 7-70v, below 30amps, and a brushed motor, yes. Amp draw is going to be the issue, some trolling motors can draw over 30amps which would blow the fuse and just swapping to a higher rated fuse is asking for trouble.

**Q: Have the same voltage coming out as I do going in, even after adjusting.  Is this defective?**
A: No, the voltage is reduced by about 1%
