Good evening, new P4 owner here, but I fly with the Inpsire series for work often! Here goes my first post on Phantom Pilots... I purchased, unboxed, and setup my P4 as the instructions specified, and charged the included battery with the A/C adapter and it went through the usual progress LED blinking cycle until it completed charging. However typically the LED lights would go off when it is completed charging, however this battery the "2nd" LED bar began double blinking. If I now try to power on the battery (inside the craft or outside of the craft), it appears to power on as usual, but shuts off after 3 seconds. I've been unable to connect to the craft with this battery. However if you just tap the button once it flashes the 4 lights indicating it's fully charged. I bought an additional P4 battery and it does not do this, but is my included battery a failure? Any help? Thanks!
