Just a quick question. Sometimes before I fly I will put a battery in my Mini 2 and turn on the controller and maybe take a few minutes to check out the settings before I go outside to fly. This usually takes me a few minutes and I may even start the motors up just to make sure everything is good. When I shut the drone down it feels warm on both sides, I assume this is the battery. Is this normal? No flight actually took place. I’m new to this so I’m just making sure that everything is as it should be.
