    I was flying my p2 today and everything seemed normal. About 5 minutes into the flight, the battery voltage indicated on my iosd went from 11.5v down to 0v and battery voltage went from 75% to 0%. The indicated voltage quickly went back to 11.something and would occasionally glitch back down to 0 for a few seconds, the % remained at 0% though. The p2 was about 800m away at 100m altitude and I was able to fly it back normally with good control and power. It was flashing red lights on the arm and am in auto descend mode so I need like 80% throttle to maintain altitude.

    What happened? Is this a bad battery? I got this with the p2 in late 2013 and it only had like 25 cycles in this and always store it less than 70% full.

    Firmware v2.0

    Where can I get a new battery that is compatible with v2 firmware? I do not want to update my p2 firmware. I don't wand to be forced to fly slower and further limit my descend speed. Does the aftermarket battery work?

    I didn't check, but should they be dirty?
