How many recharges should i expect out of a lipo?
mmeyer, yours is a fairly nebulous question and would require much more information before making a determination.
Your question is like asking how far can I go on a tank of gas. We don't know the car you are referring to, how much gas it holds, what engine it uses, what terrain you are traveling and lastly what is your driving style (little old lady on her way to church or NASCAR driver). NASCAR engines don't last long due to driving style.
Everything is interrelated so all specifications of the Plane, power system, flying style and weather conditions play a part in how long your battery will be useable. LiPo's are a finicky battery and fairly unstable chemistry. I ruined several till I figured out never discharge below 80%, never store with a full charge more than a day or 2, always store at 3.8V per cell (at least bring depleted batteries up to storage charge the day you use them if not planning to fly again for a few days). I have some I have used for 2 years with little to no puffing because they were maintained correctly. I have had some puff like a balloon in less than 2 months because stored at full charge .
