Is Great Planes LiPo 11.1V 910mAh 3S 15C Discharge Deans a good battery. I know it is the one recommended by heli-max but if there is a better battery for around the same price I would rather buy the better one. I was also looking at the Field DC Charger MKII 12 Volt but it is DC and I'm looking for one that I can use in my house. Does anyone have any recommendations.

(Do weather conditions effect the flight of the Axe; I was flying a couple of days ago and it was cloudy, damp and about to snow. The heli didn't want to stay in the air. Today I flew it and it is sunny, warm, and dry and it was hovering great.) Just seemed weird to me.
