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% ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by J***J on 2 July 2022* Worked a stated after install. Quit working after a month or so.
