I want to convert my gas gokart to electric. Fully loaded with me and the dogs, it weighs less than 500 lbs and does not need to go faster than 15 mph. We drive on level ground and only need to go around 3 miles per day at mostly walking speeds.
The rear axel has a 9" sprocket with what appears to be #40 chain and I would like to keep that sprocket and chain if possible. I see that the motors like the the MY1020 have 8mm sprockets. Is it possible to change the motor's sprocket to fit #40 chain, or should I replace the axel sprocket to accept the 8mm chain?
How many volts and how many watts do I need? Is that 48 volt 1000 watt motor a logical choice?
I will start working on the kit and have it listed here probably within the next hour.
Reverse would be great.
I ordered the kit, but will wait on the chain until I see how things go together.
I certainly appreciate all of your help with this and my many hours of research on this project clearly show that your competitors have their heads up their butts, but you take care of business. THANKS!
I'll measure tomorrow and post it here.
My engine compartment measures 18" and I hope to fit everything in there.
distance from the accelerator pedal to mid compartment is 36 ".
If these wire length are okay with you then please let me know.
If you would like any of the wire lengths changed then please let me know what lengths to change them to, and I will go ahead and do so.
I plan to build my compartment from plywood covered with fiberglass cloth and epoxy resin and all of your wire lengths sound good to me.
Great plan, that extra step of fiberglassing the plywood will make for a top quality and long lasting modification.
I entered the wire lengths listed above onto your order so we are good to go on this kit. The technician who builds the kit will make the wire lengths to the specifications listed above. It usually takes us around 2-3 business days to build and ship out kits so I expect the kit to be shipped out around the middle of next week.
My kart has 12 volt lights, horn and siren. Will there be a connection for 12 volt utilities?
There are solutions for running 12 Volt utilities from a higher Voltage battery pack though. One solution is that a DC-DC converter could be installed which would take power from the 36 Volt battery pack and convert it down to 12 Volts. We sell a DC-DC converter with an output of 12 Volts and a maximum output current of 10 Amps. I am not sure how many Watts or Amps your 12 Volt headlights, horn, and siren use so you would want to look into that and make sure that it is all under 10 Amps (120 Watts), otherwise two of our DC-DC converters might be needed.
Another solution would be to use a separate 12 Volt battery for the lights, horn, and siren. If a separate battery was used it would need to be recharged after every use, however since the 36 Volt battery pack also needs to be recharged after every use it would be practically no extra work to connect a battery charger to one more battery.
If a DC to DC converter is used it would need to be connected to a switch to disconnect the power from the 36 Volt battery pack to it, otherwise it would continuously draw a small amount of power from and slowly discharge the battery pack when the car was not being used.
We could add a DC-DC converter (or two if needed) to the kit and wire it and the controller to a dual pole single throw (DPST) toggle switch so that when the main power switch is turned on or off, it would turn on or off both the controller and the DC-DC converter. We would need to order a DPST toggle switch online and wait for it to be delivered though which could delay shipping of the kit by a few days.
