you could still find some with higher mah and get even more runtime Metalman will be able to help you with the details i am just going by what i have learned from him so far he is a genious when it comes to lipos

Well I have ran 18 at 25 -30 min runtime. I have ran 20 with the same gearing and got 34 min runtimes. If you run 12 cells and it takes 1200 watts to flip the truck over you can hammer it harder. If you have 20 cells and it takes 1200 watts to flip the truck over you can only run a little over half throttle. If you can only turn the corner at 20mph and the truck runs 30 versuses 40 you are closer to wide open as well. Yes on paper it works out some times differently than on real life.
