I mentioned in my first post that all five of my batteries seem to last only a few minutes each. After I fly, my process has always been to charge all my used batteries rite after use so if time presents an opening for flight I'm ready and go. With that, most of the time they sit for three weeks on average. My question is I'm hearing smart batteries go into dis-charging when sitting a few days plus, so should I top then off to get much longer flights?
