    say what you want about ordering cheap junk from China but i bought two of these.
    http://www.banggood.com/ELEBAR-Battery-For-DJI-PHANTOM-2500MAH-11_1V-20C-XT60-p-91256.html

    I charged them till they are green, checked them with my volt tester.
    All 12.5v. #1 4.15v, #2 4.16v, #3 4.18v
    the second battery is similar, (i thought each cell is supposed to be 4.18 though?)

    plug them into the phantom, and right after liftoff a flashing red low voltage light followed by autoland. My other brands of batteries are fine, just these two. I emailed customer service, waiting on a response.

    I found the "elebar" batteries I bought off eBay have a big difference in quality, one works almost as well as the stock battery the other will auto land me after about 2 mins (at most!) YouTube onemadvan dji phantom cooper st grassland, not the "bridge" video but the other one I use a dodgy battery for the first flight, watch how long it lasted!

    I suspect the soldering connection for the xt60 connector is **** and when I'm trying to pull high current the voltage is dropping to a low enough level to engage the auto land etc
