So I searched for this first. I have seen something on it before... O well. So I have six battery's and depending on my flight I will use 2-6. I take my P3 everywhere just in case and if I get off work early I like to find a new spot to play. But I have been charging my battery's to 100 percent and keeping them there until I need them, sometimes a week if I never get to number 6. Am I really setting myself up for failure? I work with lithium battery's a lot and just charge as needed. Do I really need to keep them at 50-75 till 24 hours before flight?
