Running the dragstrip to gather data on battery performance. The goal is to match TAG series performance level at the Atlanta Motorsports Park. Have also been testing the kart at the Lamar County Speedway in Barnesville, GA.
Motor, controller, chain, gearing, batteries, availability, weight, run time per charge, charge time, charger used, and of course cost?
Unfortunately that’s just the kit. Absolute minimum profit to me for the kit. Lithium prices have been rising and it uses top-of-the-line components. Expensive but built for the long term.Is the $8500 just the powerplant / batteries, or does that include the chassis?
Motor is air cold so it has small open vents near the motor mount. Also battery pack is not IP 65 protected so the set up is not water proof. Hope to have one that meets IP 65 at some point in the future.Have you tested in the rain yet? or is this not suitable for it yet?
Actually did not know about that. Will definitely put it on the calendar and see if we can go. Really appreciate you bringing it to our attention.Are you planning on attending this? https://www.worldkarting.com/series/ekarting/
So, it's roughly the price of a SuperKart motor. Gas Gas or one of the twins. Not all that bad for a first run experiment. Obviously as more folks start playing, prices will come down and the technology will improve.
Yes Sir and thanks. The price is if I make one. If I can make 10 or more I should be able to negotiate a lower price the the electric motor, motor controller, an lithium batteries for use in assembling the pack. Also assume no motor rebuilds … ever.So, it's roughly the price of a SuperKart motor. Gas Gas or one of the twins. Not all that bad for a first run experiment.

Really wish we could get the batteries to fit in the same place as the gas tank. Perfect location but the pack is too large at this point. Running 80V vs 100V simply reduces the top speed (but not acceleration) all other things being equal. Higher voltages have the advantage of requiring less current (amps) to obtain the same power level which means everything (motor, etc) tends to run a little cooler (always a good thing). Lots of trade offs and you make some great points. Will have to study it carefully and we really appreciate the ideas.Based on your results, you can reduce power levels to TaG level to preserve battery, and/or run a smaller battery pack. What would going to 80V instead of 100V do to longevity of runtime and power? Another benefit of batteries at the "normal" gas tank position is that mass centralization would help handling. As battery tech improves and sizes come down, I imagine this will happen...
That would be the ultimate goal. Really wish we could get the batteries to fit in the same place as the gas tank. Perfect location but the pack is too large at this point. Battery technology continues to improve so they should get lighter and cheaper if history is any indication. One advantage of electric inspire of the high initial price is that you should have no motor rebuilds… ever. No oil or gas costs and no carburetor costs … ever.I think technology is already there. What if you had a battery that fit where the fuel tank goes? A kit that required no chassis modifications or attachment to sidepods? The total weight of the kart race ready was 175 without driver? And the whole package was <$5k? That would be cool...
