Hi, I'm on latest fw, 3.0.6, batteries set to 'go home when low' mode. Using genuine DJI batteries. I've flown a fair few times but the other day had a scare when my battery meter (on Android app) started flashing low at 50% and as such the Phantom started decending rapidly (all red lights flashing) with me fighting to gain control. At first I thought the Phantom might be faulty but my spare battery seems to work fine all the way down to ~20% so it's looking like my battery might be faulty. What do you think of these stats, anything odd (apart from serial number edited out) - anyone else had such a weird fault and should my reseller replace the battery? Thanks in advance!
