“We lucked into getting our parts from Bob Batson at Electric Vehicles of America. I'm sure there are other places that you could order these parts from because they are pretty standard, but I didn't see them cheaper elsewhere on the internet.
Although I have to admit that I chose EVA because of pricing, MUCH more important than the low prices ended up being the service he provided. Bob definitely doesn't look at his job as just selling parts. He answered countless phone calls with even my stupidest questions as I was going along (I knew NOTHING about electric vehicles). I did try to read the instruction manuals that came with the parts we ordered, but maybe because I had no background in it, I got stuck a lot, and he never seemed to get annoyed with walking me through what I needed to do verbally. I know he works with a lot of school groups, and I generally felt like I needed handholding at a very elementary level, and he seemed happy to provide it.
Maybe I'm going on too long about how great Bob is, but... his service was very important because, unlike with a gasoline engine, you can't just call up any local service technician if you have problem. Things don't go wrong as often with electric systems, and they are generally easier to fix, but... if you DO have a problem you want someone that can be there immediately to walk you through troubleshooting, and he's definitely done that for us (even years after buying the parts).” ~Ron
