I've been trying to follow the guidelines for battery storage, I run my batteries down to 50% before long term storage and I have my batteries set to discharge after 48 hours. But I really like the ability to fly spontaneously, whenever I feel like flying, on short notice. I like to video wildlife, and if there are geese on the pond and I have 50% batteries, forget about it. I actually grabbed a 50% battery one time for a quick flight to fly with buzzards, and I ended up with critical low voltage and RTH. It was not fun. I curious if there is any good data on just how quickly storing at 100% damages a battery. I'm thinking about having one "sacrificial" battery that I keep at 100% all the time, but I'm wondering how quickly that will ruin it. Any thoughts?
