Behold! I have managed to sketch together a pretty impressive little go kart using an old Kettercar frame, power wheels steering axle, a minn-kota 80lb thrust 24v trolling motor, 4 dewalt flexvolt batteries wired 2s2p for 40v(36 nom) and 12 ah, and the rear axle/frame off a ridiculously overbuilt fertilizer spreader.
The rear frame and axle are high grade stainless steel, and include a 5 to 1 differential gearbox, and even zerc fittings to service the moving parts! Originally the gearbox was designed we use the wheels rotational energy to drive the actual piece of the spreader that spread the fertilizer as it rolled along. I installed the spider gear on the shaft of the trolling motor which i then attached to the frame. No brakes, no control box, just two bare wire ends wrapped around the steering wheel so i can push them together with my thumb.
The 24 volt 80 lb thrust trolling motor didn't quite have the power to get the cart moving at only 18 volts, so i doubled the voltage to 36. i understand the risks of over-volting, but its running pretty well after a few test runs. If she burns out anytime soon ill be sure to post about it. Top speed is around 20 mph, and im not sure of the range as im leary of pushing the batteries too far with no undervoltage protection in place.
Just thought id share this little project because i cant find any other examples even remotely similar to what ive built, and wanted to contribute some good information to a site i have frequented often over the years, and which i have learned a great deal from.
