Thank you so much @harmaa for your kind feedback! Really appreciate your detailed comment. For me battery duration is not that big of a problem this because of these points:

1. I try to always plan out the shoots. So when i get to a location i like to walk around and try to plan out where to fly and how to pan the camera to get some sweet short clips. That makes my air time efficient. So when i take off i fly all the planned shots and not just randomly. This saves you the most battery.

2. I always bring 2 batteries. 1 battery is rated to around 30 min, but when flying it's around 20-25 min. So say you got 40-50 min of air time. This is usually more then enough for what i do now. But if you are gonna do a longer shoot or on different locations during the day then more batteries is the simplest solution. You could also get a 12v to 110v or 230v (depending on location) inverter for your car. You would then be able to charge your batteries,laptop and camera on the way to the next location.

Thanks again for going a bit deep in the comments, it makes the whole post more valuable for others that want to learn about drones 😃
