Hello all! I'm new to this group and the hobby... I just got my phantom 3 pro the other day with an extra battery and, long story short, one of my batteries will not boot up when installed in the drone. I was able to fully charge it yesterday (1st charge) and when I placed it in the drone today it would not start up. Upon hooking this battery back up to the charger, I get a 1-2-3-4 sequence of green LEDs followed by the red power light (see what I mean in the video link here: ) Is my battery defective? Any suggestions? Thank you!
