I have two batteries which were purchased 5.5 months ago. One has been discharged 24 times while the other has been discharged 31 times. I did a firmware update this afternoon to see if that would help my short flight times. I am only getting 5 to 7 minutes where as I use to get 17-18 minutes before getting the red lights. One battery surprised me last week while over water, had to quickly fly back to land since the copter was trying to land itself. The other battery seemed ok then. Now today both batteries are giving me short flights-- 5 minutes on one and 7 minutes on the other. I checked the last battery immediately after the flight and the % charge was 49% and the battery life is at 92%.
Cell 1 3805 MV
cell 2 3821 MV
cell 3 3746 MV
I completely discharged one battery earlier and recharged it and then did a test hover. In 7 minutes my voltage dropped to 10.9/10.8 so it landed. I hope these batteries, for what I paid for them, are good for much more than 5/6 months.
Any ideas anyone.
