I'm currently using the kit 3D robotics setup and I'm looking for more battery life. Completely stock I got around 5-6 minutes, and with a camera setup I'm closer to 3 minutes. This is all on 3s 2200mah 40c packs.
At what point would increasing the battery capacity detract instead of help improve flight times? Maybe bumping up to 3000mah would be better?
Also, am I correct in assuming that a bigger quad (bigger power system, or octo) will have a longer battery life?
