so yeah i am making a electric go kart for a school project but the problem is i dont know how to power it and i dont want to spend money on expensive motors , so my question was this go kart will be powered by car batteries maybe a max of 4 , and can i use 120volt motor to make to go kart move or will the amount af batteries be too low for it to even budge and i was thinking of useing a electric lawn mower engine will it be able to push like 200 pounds at max? and how fast will it go , and i was also wondering would it be a good idea to just use those little grey looking motors in car engines ? will that go fast with four 12volt car batteries , i was gonna make a gas one before but the engine prices were too high so yeah help me out here i am a total newbie and the frame is gonna be built out of hallow metal pipes and rods so its strong but not too heavy , so tell me what to do and how to do it , electric lawn mower 120v motor , grey car motor or a 120v electric motor??
okay how about stuff i can use from a broken car , can i use the car starter motor to power my go kart with four 12 volt batteries will it go fast enough?
