Always have a battery in but I don't really "store" it for long. I try to fly every day if the weather allows.
Just be sure it's not fully charged for a long time.
Me too. They regularly drain down slowly when I can't fly.Don’t the batteries self discharge to 50% if not used for 10 days or so? I’m in Cornwall uk and not flown for for over 2 weeks because of rain and windy weather, when I checked my batteries, all had dipped down to 50-75% charge.
