it looks nice but how do yo managed to run 24v motors from 3 12v batteries connected serial? with control unit?
Um...oop's it's been a while since I built, that kart
IIRC it started off with the (2) 24V motors (& 2 12V batteries)

...but, it wasn't very powerful
...&/so, by the time I did this video, (I think) I had upgraded it to (2) 36V motors, that were powered by (3) 12V 12AH SLA's
Here is the upgraded version
It's called the Land Speeder

...& it is motivated by (2) 48V 1,000W motors

...& powered by a 48V 50AH Lithium battery module
