Hi Guys,

I have the problem that I can´t update the firmware on my 3rd battery. And I am not able to use the battery until the firmware is updated.
First two batteries worked without any issues but the third will get stuck at exact 15% and the FPV Drone will start over and over again until this message shows up.
Update failed (1-2-6)



I´ve tried it via DJI Assistant 2 and via the Goggles.
With both methods it gets stuck at 15%, the Drone starts over and over again until an error message shows up.
Another detail I just noticed:
Only the batteries middle two LEDs are shining. It doesn´t show the tipical LED loading pattern anymore when connected to the charging station.
Same thing when it is not connected to the charging station and you put it in the FPV Drone. When you turn it on, only the middle two LEDs are shining.



Does anyone know a way to reset the battery somehow? Or another way I haven´t tried yet to solve this issue?
Could the battery be broken?

Did you tried it with the drone, and goggles and radio connected to fly app in the smartphone?

Battery firmware updates are normally sent from the drone. You don’t need to do it using Assistant or the Fly App, once the goggles is connected you should get a request to update, which will be done without the need for the Fly App or the internet.

If your battery won’t charge it will probably be faulty. Raise a ticket with DJI, there is not a reset for the battery.

I also suggest using the Fly App connected to the goggles.

Contacted DJI Support.
They confirmed that it´s a battery error and that there is nothing I personally can do to suddenly make it work.
Doesn´t matter wheather I try it via Fly App with goggles or with DJI Assistant 2.
So I sent it in and got a brand new working battery.

Great news! They really seem to take care of those with problems.

Inner 2 lights after charging the battery means that it cannot balance the cells. One of the cells is faulty.

Its the same error light on all DJI batteries.

my first battery set had one like this, same sent in for repair

I just had a new battery that was charged maybe twice sent to them and instead of sending me a new one they said they'll replace it for full price and then they tell me they give me a 40% discount.

The battery had no issues until the update and instead of apologizing for this issue they are making you pay for a batter

THATS THE WORST CUSTOMER SERVICE EVER!!!!

I can't believe that they are making me go through this issue, I am going to start legal action.
