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.

Tag's may have the HP for those times, but certainly not the clutch!!!
Very interesting project, to say the least. Electric will be the thing at some point.
If you don't mind,... Motor, controller, chain, gearing, batteries, availability, weight, run time per charge, charge time, charger used, and of course cost?
Very impressive numbers. Please keep us informed.

Thanks Sir. It is sold as a kit and should only be used with shifter kart chassis.
AC-9 motor from HPEVS, 1238E Curtis Controller, 100V/46aH battery assembled by Vextrek (Augusta, GA). CC/CV charger from Thunderstruck Motors with a CANBUS network that communicates with the BMS. Can run 15-16 laps at wide open throttle at the Atlanta Motorsports Park (.83 miles long with 43ft.

Basically you “top off” the battery in between races since you are not likely to deplete it unless d”racing more than 15 minutes straight. We have it mounted on a DR shifter kart and everything weighs 310 lbs without the driver.
$8,500 …. Available on demand if you live in the Southeastern USA.

Is the $8500 just the powerplant / batteries, or does that include the chassis?

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.

Have you tested in the rain yet? or is this not suitable for it yet?

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.

Last week, we were allowed to race against some vintage and modern 2-cycle karts at the Lamar County Speedway in Barnesville, GA. Really great group of people. They did not have to let us race but seemed interested in the project so they let us race the gas powered karts. Hopefully, we will get to run against some TAG karts soon. Our ultimate goal is a 52-second lap time at the Atlanta Motorsports Park in Dawsonville, GA.
Here’s a brief video of the Barnesville race. Vextrek is the #6 kart driven by Adam Phillips

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.
