I have the fly more combo with three batteries and a hub.  One of my batteries when placed in the hub has the third LED blink three times.  That battery when put into the drone is unresponsive and doesn't power the drone up.  I've tried moving my batteries around between the three ports and the other two batteries have no issues and the blink pattern follows the one battery.

In the hub's manual it says:
The abnormal status display of each battery status LED array is the same as the one for the battery level LEDSs on the aircraft when inserting the battery into the aircraft.  Refer to the Mavic Mini user manual for more information.

In the Mavic Mini manual it says over-voltage charger detected.  I'm using the DJI wall adapter and cable and the other batteries don't seem to have any issue with the hub, so I'm thinking this battery is having issues.  Is there anything I can try to get this battery working?

I tried putting the battery in the drone and plugging it in.  I get all four LEDs flashing.  I let it go for about an hour and it didn't seem like it did anything.  Returned it to the hub and it still does the three blinks of LED 3.

I took a couple of quick videos but the forum is pretty restrictive.  The videos were .mov from my iphone which isn't an allowed format.  I tried converting to .gif but the files are too big.  Can you let me know the best way to get the videos to you?

I have the same issue on mini 2. The drone is new, i bought it yesterday. Only the battery that was inside the drone does this, the other two are ok.
The 3rd led blinks 3 times fast at an interval of 5 seconds.

Yea, convert the video into a format other than an Apple proprietary format.
.mp4 comes to mind.

I just received my dj Magic mini 2 today and this is exactly what is happening to me. The battery that came installed in aircraft is the one that has the third light blinking three times when charging in the hub. The other two batteries are fine. I also was missing cables props screws and other stuff in box but that’s a separate issue.

Try converting it to almost any non-Apple proprietary format.  .mp4 comes to mind.

Hi I have one battery out of 3 that does the same thing in the charging hub and looking for an answer if the battery is okay or need to be repaired. Because it shows all four lights lit in the drone and it flies too. I have mini 2 fly more combo. I have video clip from my iPhone and converted it to an mp4 file for this but this website wouldn't take mp4 files either.

Do you checked out if there are dust or anything else is on the contact of the batterie, even on the contacts of the hub? What heppening when you change the 3 batteries in the hub? Is there only the problem at the 3rd loading point?

Are you using a 2A charging  transformer.
If a battery is to worm it will nut charge.if in a charging hub it will only charge the fullest battery first then will go to the next fullest .
Just a thought.

Did anyone find a solution for this issue. I bought mine today and have exactly the same problem. Using everything that came with the combo to charge. Only the battery that was in the drone when opened has this issue.

I got the same issue on one of 3 batteries in the combo. I have left one of the batteries in the drone after flight, and after 20 days it blinks 3rd LED two times. My guess is that the cell voltage level fell below the threshold, and the charging chip refuses to charge the battery.
I have tried measuring the voltage on the terminals, but the only reading is 3V on the C and D connectors, same as the working battery.Looks like the charging controller does not allow access to the individual cells like my previous drones had.
I have contacted support to see what is their solution...

Hi, I have 3 batteries off my mavic mini in the charging hub and the following is happening

Battery 1 - light 1 and 2 flash in sequence 5 times quickly, like it is charging.

Then the following lights flash 3 times
Battery 1 - light 1 solid, light 2 flash
Battery 2 - light 1 flash
Battery 3 - light 1 flash

I know the batteries are low with battery 1 having the most charge but I've never seen it do this before.

Can't see anything in the manual

Any help?

I have a brand new DJI Mini 2 with the same issue. One battery blinks three times on the fourth light. Other batters charge fine. Do I need to exchange this at Best Buy? (Literally bought this TODAY, the battery in question was used once)
