This is a conversion I did a few years ago. It is a 1987 Ford Ranger that I already had. The electric motor is from a forklift. The controller is Open Revolt that you put together yourself. The charger is homemade, rectified mains with a couple inductors, caps, switches, and timer etc.
The batteries are from Wal-Mart flooded deep cycle. Not the best to use but I did all this on the cheap. My range is 25 to 30 miles in the summer, and half that in the winter. There is no heater so it is not driven much when it's too cold.
I have had it up to 60 mph but the range is cut in half at that speed.
Just thought I would share since there were no other post.
