Can't argue with the reasonableness of maintaining a minimum 20% charge, but I get the feeling it's just a number picked out of the sky. I like to keep my post-flight voltages above 3.7V, but I have no data to say 3.6 or 3.5 wouldn't produce comparable battery lifetimes. Overuse is bad, no question. But do you really have any hard data to back up an actual number? Or would you admit this just seems like a reasonable rule of thumb? (I'm actually hoping you have the data -- I'd like to have a look
