Hi everyone!
Does anyone know what the flashing of the two middle lights mean? I put my battery on charge and the two middle lights along with the power light blinks for a second or two and go away. I left it charging for more than 5 hours but still nothing. Any ideas?

Hi there, the battery needs a firmware update. Please insert the battery to the drone and refresh the latest firmware via DJI Assistant 2.

I did connect my drone to the software using a working battery and noticed that the firmware is up to date but when I plugin my non working battery nothing happens. How can I update the firmware when the battery doesn't 'boot up'?

Did you ever find a solution to the problem? I have the same thing on 3 batteries. The Drone does not power on in this state so I cant check the firmware. Reset did not help either. Negative terminal to the reset button.

No luck had to discard the battery.
