I've been flying drones for a while starting with the "toy drones" that cost from $50-200 that are rough to control given simple electronics. My Holy stone hs100 is giving me problems with the battery indicator icon saying battery is dead when it's not. All 3 batteries the same. Afraid to fly without keeping an eye on the battery light on the drone itself. I mean isn't that what the icon on the fpv screen is for? Holy stone washed their hands of this drones they're telling me. Ideas?. Batteries are new or almost new.
