Year 2014 my son wanted to build wooden gokart, but it did not go nowere.
So I bought old soviet rolling frame and installed ebay 1kw electric motor with controller onto it.
Also took 4pcs of 40Ah old UPS batterys and this was my first kart, capable of doing 30km/h and could be run for 1h, then had to be charged.
When I bought it.

When installed electric components

After that there was will to do faster and better one and I bought a used Tony rolling frame (that was in 2014 october). And started to search electric components. Was a rookie then and bought myself Golden Motor 10kw aircooled mootor + their 10kw bldc controller. Batterys choosed 16pcs of LiFePo4 60Ah winston cells. It took the whole winter to install it and finised in march 2015. And it looked like this:
After that I just could not stop myself anymore and it all evolved to 60kw kart, capable of doing 0-60mph in 2,6seconds and in kart track ~2s slower in track than professional rotax max of dd2. In hobby events with 20 karts in the track all 125cc I finished in 5th place usually after 10 laps.
