Converting a Dodge Caravan to Electric
 

I have been given a 2001 Dodge Caravan that needs a new motor. Would anyone have an idea what it would cost a DIY'er to pull this off and would it be worth while?

Seems like it could hold a lot of batteries............

check the curb weight and the gross vehicle weight to see how may batteries you can fit in there without your insurance freaking out if some crashes in to you.
in the early '90's dodge built an electric mini van, I've only seen one in person but it was pretty nice, the battery pack was huge tho.
thing that you are going to want to look in to tho is replacing the automatic with a manual transmision.
