Couple things, and yes I know how to break a Lipo in !. We have all been back and forth on the "Supposed" correct safe voltage to land at approximately 14.7 v, but something is not correct, or am I seeing things wrong ? First off I charge 100% to 16.8v, If I fly at hover/or not, down to our supposed 14.7v, I still have according to the 4 green battery level bars 2 bars left= 50% charge left (Yuneec says the bars are accurate?) And then they charge back up to 100% in about one hours, not the 2.5 hours, so that confirms that I am only using about half the battery available. I do realize that with Lipo's that there is a fast drop off in voltage the last 20%, but hell ! I think we could fly down below 14.7v to get a safe full voltage? What do you all think? Stopping at 14 minutes/14.7v is nowhere near the specs listed by Yuneec !
