Gens ace 800mah 3S1P 11.1V 20C Lipo battery pack
Review: Good battery for the 250 class heli. I run these in my Trex 250 with the stock power system. The Gens Ace packs perform well to 4:15 of hard flying. They fly just as good as my higher priced packs with a higher C rating. 20C is under rated in these packs they are one of my favorites.
I have 50 flights on each pack and have charged at 5C many times, the packs fly like they did when I bought them. No puffing, and they run very cool. Barely warm after the flight and they actually cool down while charging at 5C! I just bought a 6S pack for my Protos and hope it does just as good. If it does, I will fly Gens Ace from now on! Thanks."
