    I thought I had it charged last night, but didn't plug the balance thing into the charger.

    I followed the instructions from DJI (Set the switch to 2A and plugged the balance cord into 3S), and it has been two hours. Still not even charging. There is a blinking red light instead of a steady one.

    Update: I found a spare battery I had forgotten about. Plugged it into a different charger with same settings, and it is solid red.

    If the battery is severely discharged, it will sit there and blink until it gets within charging spec. It's fine, just takes a while. I lost my bird for an hour or so and when I found it the battery was down to 5 volts or so. The charger just blinked for like 2 or 3 hrs and then it finally started to charge and the battery is actually fine still suprisingly enough

    I think I just got a bad battery. I had it plugged in all night, put it in my phantom, and it did the same thing. I put another battery in and it flew just fine
