Drift E Go Kart

Hey everyone,
I am looking for some help in building an electric drift kart. Right now on our drift go karts we run 212 Predator engines with PVC pipe around 1 rear wheel to reduce traction and let us slide easier. I think an electric go kart will be really fun, for the fact that the electric motor will have instant torque and thus hopefully eliminating the need of PVC.

Anyways, I've been doing some research that has led me to this forum. I am not sure what is the best motor/controller combo for what I want to do. After a bunch GOOGLING I found this site, /https://www.electricmotorsport.com/ that is located down the street from me. For a motor I think I like the ME11115 And for the controller the Sevcon Gen4. Every time I think I find a piece to the puzzle I come up with more questions, like for the controller, do I need to "program" it to run it, or only for more advanced features?

For batteries can I use a bunch of Lipos that I run on my RC cars wired in series?
Any and all help is appreciated.

Thank you

P.S. Sorry if these are dumb noob questions, I'm an electrician not an EV specialist.

I'm not quite sure how to answer what is best for you as I don't fully understand what helps to make the best drift vehicle.

My assumptions would be:

Rear bias on weight to help throw the back out easily
Low weight isn't that important
Massive responsive torque is of prime importance
Competitions are short in time duration - a few laps per "heat" if you will

So what my best WAG goals would include:

Strong motor (not sure how much is enough due to tire size, stickyness, track surface, etc)
Short gearing (torque is most important)
Simple battery construction (weight not that important)

I'd take a look at my spreadsheet in excel (macros copy the selected items data from the tabs). Select various motors, controllers, and gearing to get you in the ballpark. Note that these are all AC motors, and for your purposes a simpler/cheaper DC motor could work just fine. Choose some cells to match, realizing that lipo packs are probably your best best for simplicity and maximum amperage per weight. However the quality is questionable, so be careful charging, storing, and discharging - and I would not store one of these battery packs in my garage, unlike a cylindrical or car derived pouch cell pack.
