I'm using the DJI Phantom copter with GoPro Hero 3+ camera, DJI AVL58 video transmitter, Hifly 2 axis gimbal. - What is the safe and perfect time duration, can I fly the phantom with a single battery? - Does phantom have any low battery indicator, should I turn it on, through the software? - Does the flying time of the battery fade away, when it gets older? Please share your opinion with me guys.
