I have two batteries total. Do I have to let the bird take a break in between battery changes?. I have my battery warning set to 25%, when I get the warning I start bringing my bird down until I land it. Then I pull the depleted battery out and insert a fresh, fully charged battery - I would say this process takes a good 5 minutes. Then I fly again until my second battery runs out. Am I going to hurt the motors if I do not let bird take a break in between changes?.
