I'm not talking about charges between flights (although checking between flights is a good idea). Just between flying days. The plane is sitting there doing nothing the night before going to the field so why not charge it? Shortening the life through charging really depends on the battery chemistry, the charge rate, type of charger, etc. I believe. That's the good thing about charging before a day of flying, you have time to charge at a lower rate which is much better for the battery in the long run. Regardless, I'd rather use a up a few battery cycles if that were the case than lose a plane. That's just how I see it. I'm one of those very thorough, meticulous types that likes to take care of every little detail, leaving as little as possible to chance.
