    I have only one flight with this set up and gained only a couple of min at best. I was running beholder gimbal with gp3+ ,stock 8 props. My guess is it's all about the weight. The extra 200 gram battery weight sucks the time enough to not really be worth it.
    I'm sure this has bee hashed out before but input would be appreciated.

    You're right that it's all about weight. You also want to make sure that you're running your batteries down to an appropriate 75-85% discharge. Depending on your total weight, you should expect about 1.5x flight time with double batteries. I get a significantly better ratio than that by being obsessive about weight, but if you want increased flight time, dropping your all-up-weight is going to be best option.

    My try with dual 2200mah was 9:30. With a single 2700mah about 9 minutes.

    For most people, I agree that a single 2700 is the best plug and play, bang for the buck battery option out there. Fully loaded with gimbal, VTX, 9" props I get 12.5 minutes with a 2700 and 15 minutes on dual-2200. If the 2700 came out before I did my dual battery mod I might have gone a different route.

    I have heard one might get half the flite time from additional battery. If I were to get 15 min total With 2200 : I would be good. I just have not found the time. Do yo know how much 2700 bat weighs vs 200 gram. 2200?

    Is there any problems with spinning 9" blades? Are motors the same in v1 and v2?

    Guess all things considered if the times are the same it would seem I should shuck the dbl setup and go for better flight efficiency

    That's the best plan esp if you're already loaded up a bit before the battery.

    Motors are the same in v1 and v2 Phantoms (and in the Flamewheel ATF kits DJI sells as well). Running 9" props on them is fine, and the stock P2 props seem to deliver the best flight times out of the many options available.

    Motors are the same, 9" props work great.

    2700mah battery is 202g. Stock phantom battery is 173g. Give or take.

    If you're over 1200g auw with single battery, just go 2700, you're already lugging a lot of extra weight around :)

    I got the dual battery mount last week and I was disappointed. I got about 2 minutes more with 2 batteries so it hardly seems worth carrying around the extra weight. and using your batteries twice as fast
