Donor Car

• When converting a gasoline-powered vehicle to electric, find one that has a blown engine or major engine trouble, but is in otherwise good condition. Geo Metros are especially popular for this type of project because they are inexpensive, lightweight vehicles.
  
  

Electric Motor

• Find an electric motor that best suits the vehicle you've selected. If you're on a tight budget, try to find an old electric forklift because those electric motors are easily adapted for a car.
  
  

Batteries

• Batteries range from cheaper lead-acid versions to more expensive lithium-ion batteries.
  
  

Controller

• The controller works the same way a throttle does in an gasoline vehicle and regulates speed.
  
  

Battery Charger

• A battery-charging system makes it easy just to plug in one cord to make sure all the batteries in the pack are equally charged.
