Hey there. Because of my AirPro madeshift mounted on my Walkera Runner 250, I have to protrude the battery more the halfway outback plus add a counterweight for balance, using a smaller camera that’s not really useful.
So instead, I would like to put a larger battery. I noticed the Walkera 250 batteries are the same as the Phantom 1’s: 11.1V, 2250 mAh (25Wh) battery. Is there a version of the same battery, with the same plugs but about 1.5 longer with more battery cells and therefore more mAh’s? That would really help me balance out the AirPro’s weight and at the same time increase flight time cut in half by the overweight setup of the drone equipped with that high quality camera.
