You really have to try it to believe it. I use these on my MSH Protos 500 and the machine is terrifyingly fast. And the batteries are light too, per unit of energy. These make Thunder Power batteries look like "girlie man" batteries. They are expensive, yes, but boy are they worth it if you value performance at all. TC
I am running this pack in my T-Rex 500... WOW! It outperforms my dual 3S in series by far! You have to do the canopy mount mod to get it to fit, but it's a awesome pack past that.
