    Anyone fly with extra battery packs?

    If so, how much additional flight time do you get?

    I would imagine with the extra weight that one does not get proportional flight time as with just one battery.

    Thanks!

    It also depends on the AUW of your Phantom, so if you run stock Phantom, with 2 packs you may get 18-20 minutes instead of 12 minutes with 1 pack. But if you have video gear, you may have 8 minutes in stead of 5!
    It is also depends on how you fly, your prop and your location altitude as well as the pack quality.
    Below are the results of my test of Phantom with only camera mount with various kinds of props as well as the sound level.

    Prop time (min:sec.) sound (dB)
    Stock 12:48 83
    Graupner 12:40 84 adjust throttle a few times
    GWS 13:39 83
    MasterAS 8:33 84.5
    APC 10x3.8 cuttip 13:54 84
    Gemfan 9x4.7 14.06 86 stable, hold atti well
    APC 9x4.5 oscillation!
    FC 3-9x4.5 11:31 92 adjust throttle 2 times
    FC 9x4.5 11:42 90 stable, hold atti well
    Gemfan 9x4.7 14.22 86 stable, hold atti well Nano-Tech A-Spec 65-130C
    Carbon 9x7 13.29 90 slight oscillation (´âáreduce Pitch & roll to 80%)

    Carbon 8x4.5 with Contour weight = 2.25lbs or 1020.583 g. 8:40 minutes.

    Stock 19:45 (2x2200 mAh) 2 packs

    Thanks!

    I'll have to run my own tests so that I can have a grapple on flight times and plan accordingly!
