Electric Outboards

After doing some research into Chinese copy-cat outboards, i visited one manufacturers website and found they are making electric outboards aswell, which run on a 48volt system from 4 12v batteries wired in series.
Looks like some interesting technology with the potential to grow, which would really be limited by only battery life.
The engines only weight about 65-70lbs, but having 4 batteries will add quite a bit more, but depending on the application and size of boat this may not matter.
