Thanks for the heads up guys. I was looking at those SMC packs because they are one of the few that fit the emaxx stock battery trays and by their rating they should be good for 252 amps continuous. You would think thats more than enough?

Stellor5, You might want to invest in a wattmeter. It helped me by seeing how far low the voltage would drop vs amp draw. This might give you a better idea to see if you can gear up.

I'm not sure if its recommended on the 2200 but adjusting the timing up helped get me a couple mph out of my setup. I setup for about 42mph right now and its really plenty fast for a large MT. If the batteries are sagging voltage under load, then a better set of batteries could be good for an easy 5mph.
