With one battery you fly for about 30-35 minutes

The 180 minutes refer to the RC Pro Controller. You can fly with it for this time. As the others have already written, a battery lasts between 30 and 40 minutes, depending on how you fly. It is therefore worth buying a few of these batteries so that you can fly for longer. Have fun with it if you decide to go for it. It's a really good drone that gives you a lot of pleasure.
