Went out for a quick flight on 92% battery, could not get GPS mode to engage though 7-10 satellites (also had problems getting GPS earlier today), flew anyway, approximately 300ft away the battery icon on the began to blink and I could see the P2V starting to slowly descend (in a very bad location). I gunned it for altitude and steered it towards home and luckily it responded. As it was heading my way the battery icon went from red back to green and then back to red. Landed, turned battery on/off and flew another 7+ minutes without issue. I'm fully updated, no issues with erratic flight. Anyone else?
