Most of these use parallel, matched mosfets.  There are homebrew
electric cars on the net - most of them stick with manufactured
controllers, but some have built their own.  One recently mentioned (I
think on this list since he's using a pic) uses two very large DC motors...

Google for it.  (I love when a company name becomes a verb!)
