I have been reading every topic in every forum for the past week in an effort to determine which mods will yield the best increase in battery life. This is the setup I have: DJI Phantom 1.1.1 Zenmuse gimbal GoPro Hero 3+ These are the upgrades that I think will achieve the best battery life: Dual Mad Dog 2700mAh batteries Vision Props. Can anyone provide input regarding which upgrades, i.e. battery, props, have given them the best flight times with the above setup? I would appreciate any help! Thanks!
