Found the site. The batteries do indeed look the same. I might be interested in ordering a couple of batteries from them since it'll be faster and close to the same price. I just wish they posted dimensions for all batteries, not just some of them on the site!
Yeah I think they are the same batts. Also I wouldn't order without the dimensions. So the one I ordered definitely had dimensions.
And Ezh pinion size is a preference and depends on the conditions your running in. Are you going for speed or running at a track, short track, long track etc. But you do need a "mod 1" pinion size.
