I found this kit on Ebay for $299. What do you guys think? It seems like it has everything I would need except for batteries. If its not a good deal what would you reccomend or why is it not a good deal?

I just scored a Workman Dual Tandem which I would like to have converted over to electric for longer trips for groceries and maybe even commuting to work. The idea being to use the cars less for every day tasks.

Im also confused about batteries. I went to ElitePowerSystems.com and found several battery packs that were in the $200-300 range. Do I need to buy 4 of these to power this 48v motor?
