Hi, I just bought a Phantom 2 a few days back, not the Vision, the one with the Zenmuse for GoPro. From what I've read and been told, the LED lights are supposed to go red once it reaches low battery levels. But from the couple of flights I've made, when it goes low battery (only one light left on the battery) the LEDs on the aircraft stay the same, the front ones red and the back ones green, what can be going on with this? Also the controller light has always been solid red, never changes to green, I've changed the AA batteries to make sure it wasn't a battery issue, still the same solid red lights. Any ideas on this couple of issues? Thanks.
