So I’m trying to build a quad, not for speed but just for cruising and taking some cool shots here and there. I don’t want to fly for 2-3 minutes and swap out a battery every time because that’s kind of just stressful.

So I’m thinking, if I reduce the C rating, my motors won’t demand as much power so then I could potentially have longer battery life right? Is that how it works? Any chance I can get at least 15 minutes of flight?

EDIT: Thank you for everyone's advice. I think I understand this a lot better and got to a point where my 5" drone's weight is ~351g (includes props, DJI FPV, motors, receiver, etc).

Based on that, the lightest and highest mAh LiPo I could find is 215g for 2000mAh and that brings thing up to 566g. I used a site (https://www.omnicalculator.com/other/drone-flight-time) to calculate my potential flight time and it looks like if take things easy, I could pump out ~14 minutes. The battery is definitely a bit expensive, but at least for now I know I can pump out a decent amount of performance while also getting a good amount of flight time.
