Yeah, 12Ah would be kinda heavy at 1.2 lbs.

I get close to an hour on a warmish day (45min track time) with my 5.8Ah pack on a 4600. But this setup only does 47ish mph. If he went with the 5700 with the same gearing I'm using (54T/22T), he should easily get 55mph especially considering he's going to stick with the two speed tranny. He could actually gear a little higher since he still has first gear and get close to 65mph if not more. Since the 5700 is a little hotter, 8Ah should get about the same runtime if not a tad more and not be too bad on the weight. With that power on a 2wd, he's gonna want some weight for traction!
