I have a Phantom 1 with a version 3 upgrade board. I have the H3-2D gimbal with a Gopro 3+ black a mini iosd and a 5.8 Ghz video transmitter all wired in and functioning correctly.
When the props are NOT connected I can power up full throttle and everything will operate normal for at least 8 - 10 min. If I connect the props and attempt to fly as soon as I get 5 feet off the ground I get the low battery warning and the quad will land. I have tried this with 5 batteries (2 DJI and 3 aftermarket) all with the same result.The quad flew fine with the upgrade board installed before the addition of the gimbal and mini iosd but with a stationary camera and video transmitter.
Is this a sign of weak batteries? I can't speak for the age of the batteries as I bought the quad used and rebuilt the internals. I don't want to invest in new batteries if it is something more like weak motors because I already have to much invested in this project.
One other important point. These same batteries get a good 10 min flight time (or more) on my other Phantom 1 with no camera just a bare quad with all first generation parts. I also tried multiple versions of firmware because I read that could be an issue.
The enclosed pic is the inside of the quad. That is not burn marks on the wires. I used a cheap lighter to heat the heat shrink tape.
