Awesome build! Anymore updates?

Had this on my race kart. It is perfect If you are looking to power a low cost high HP industrial motor like a forklift or golf cart motor etc. Everything is wired and ready to be mounted. Fully programmable via laptop/pc. -Kelly KDZ48400 controller -48v contactor -J1 cable -Programming cable...

3hrs is a long time. Do you really plan on riding it for 25-45miles? If you only need a total of 10-15miles the 12ah batteries would probably be close and the 22ah batteries shouldn't be an issue.

First thing I do on mine is swap out the motor sprocket from 11T to 9T. Gives it a much needed increase in torque. I have a 1800w boma on my bench I still need to install as well. http://www.diygokarts.com/vb/showthread.php?t=40558

Pick up an industrial motor for 100$ on ebay. 1hp Leeson or clarke will give you what you need. If not get an imperial 3.6hp forklift motor. http://www.diygokarts.com/vb/showthread.php?t=39038

Ok you have had plenty of time! When we going to see some video of this thing in action?! :auto:

Looks awesome! Also check out the Razor Dune buggy. Similar looking, easy for kids and fits an adult.

What he said^^^ People are building some pretty cool race karts under 500$ http://www.powerracingseries.org/

hoping at the end of this 16days to save thing they have going on ends with a coupon.

Welcome to the forum! Also join your local Facebook gokart page and you might find someone with the same kart that you can look at for comparisons etc.

What he said^^ How do you make the mold?

Love this project! Thank you for the update. I just picked up a half melted ATC70 and have been considering doing electric. Any chance do you make any ATC plastic parts? I could use a number plate. :)

Batteries are on sale again!

Might be able to use something like these for your drive wheel(s) https://www.surpluscenter.com/Electrical/DC-Motors/Special-Purpose-DC-Motors/180-Watt-90-RPM-12-Volt-DC-Drive-Motor-Only-Good-Tire-JD-HUB-24-13-1516.axd

Seriously, you post a ton of helpful stuff. Thank you :)

The dingo axle sprocket looks much bigger then 60T. the 1800w motor will be fine but you need to gear it properly. Also sprockets are cheap..

Buy the biggest axle sprocket you can fit on your cart. That little motor is going to need all the help it can get to move that beast.

What kind of axle sprocket are you running? Can you post a pic? You might want to go to ebay or bmikarts and grab the biggest one you can fit. With your setup I would want at least a 90T or bigger. Or go with an industrial motor. Imperial 3.6HP motors are cheap and easy to come by on ebay.

If it is easy to get to do you have the measurements on your 1800w motor?

Well the motor came. The good is it says 1800w on it and came with the mx throttle. I cant believe that it is smaller then a brushed 500w motor! Weighs a ton though. The bad. Came with an 800w controller and no foot pedal...
