One of my batteries already has this issue after just 2-3 cycles; when at about 50% sound alerts and all leds flashing red, auto decline kicks in. The other battery however is still working as expected.
That is disappointing but does sound more like a manufacturing defect rather than disturbingly short lived one.
Maybe it got a bang in transit.
Do you know if that was the 'additional' one - and was it packed in the card box with foam lining a new battery comes with?
Unfortunately I mixed them up and can't figure out which it is. The additional battery was packed as you describe and looks unused and undamaged, no deformations or bulging. The box looks legit, can't remember if it was sealed in any way.
I'll return it and get a replacement. Then I will keep a close aye on this thread and see what happens with this issue.
It is rather disturbing that one can not depend on the battery meter or the leds on the battery itself. Regardless if the battery has a manufacturing defect, if the life time is crap or the firmware is buggy it should not jump from looking very good to sounding the dive alarm and start declining in an instant. This behavior is bound to put my phantom in the Baltic Sea sooner rather than later... :shock:
