Since you said that I have to ask about the 60% storage VS fully charged.

I was talking to one of the pro's and he said he stores his lipo's fully charged and the tops them off. If he just runs them he can notice a difference in punch.

I have been doing the 60% deal and so don't see this and when i was storing them full I would run practice and they were freshly charged for the race.

Any idea what that is? is this the why not to store full or just an indicator of the damage caused by storing them full?
