Very interesting! I'd think that using all the capacity of the battery has got to be better for the battery also. Now, the question again, is how do you know when you're getting close to the rim of the cliff and how do you know if you've gotten too close? I understand about the cycling part but, how does that relate to when you are at the field, wondering if you can get another flight in on the battery? You would have to cycle the battery down from that voltage, to know how much is still in there, wouldn't you? Your chart conveniently shows a "cliff" where the battery's voltage drops significantly. At some point, every battery will get there. My fear is that my plane might be 100 feet high when it gets to that cliff and I'm at ground level. I don't want to beat a dead horse here but I sure don't want to trust blind faith at the fly field either. Any info would be great.

thanks!
