I could have saved a lot of money by buying more used parts (brand new batteries were almost 1/2 the total cost of the project). However, I didn't have a lawn mower at the time and needed something working to cut the grass! Now that its all together I wouldn't ever want anything else. I really do love it.

You got your motor for a good price, my slightly used Etek cost me $400.
Batteries I figure are going to cost $400. to $700. +???
I'll need a 48volt contactor and a 1 or 2 meters.
Everything else I have or can make.
So I figure this conversion will cost $1000. to $1500. ???
