My 1st post, so forgive me if I've created a long post than normal!
A DJI Mavic Pro Battery issue.
It seems this is a common issue, I have written to DJI Support with the same problem.  The reply from them after the following Msg was to ask if the green light blink twice or three time per minute. In my situation, I get a single Blink every 15 Secs. My Msg to DJI is as follows: A DJI Mavic Pro Battery issue. Yesterday I assembled and set-up my new DJI Mavic drone. Initially, I had difficulties in updating the firmware, on the couple of time it took me to unsuccessfully down load it, the original battery at around 50%, started to have problems and would not turn off.  It seemed to lockup with to two (2) centre LED on green and occasionally plinking of and back on to green. Eventually, my only option was to remove the battery whilst still on. I then replaced the battery with my spare one, and successfully down load, install and set-up the firmware. At this stage I was able to Stop, Start the drone at will and operate all the features. Overnight, I put the locked battery on the charger hoping it may discharge and recharge the battery. Unfortunately, that didn’t happen and now, after 24 hours plus, the battery is still showing the same two green LEDs and occasionally blinking. Has anyone else experience this situation and how can I rectify the problem without having to replace the $150 Battery.

Had exactly same issue!!
Battery was perfectly fine and error occurred during update from .700 to .800.
Why should I send it back??? Is this safe??

ANSWER ME DJI. The battery was fine, maybe 2 - 4 times used.

I put it for safety reasons now far in my backyard in a Lipobag.

I am in doubt if I bought the right drone.

ANSWER ME DJI.

How to fix my new battery?

The battery was fine, maybe 2 - 4 times used.

I put it for safety reasons now far in my backyard in a Lipobag.

I am in very much doubt if I bought the right drone.
I have only crashed app, updates on updates, a broken battery and just less then half an hour flighttime with crashing DJI Go 4 app.
Besides the privacy and restrictions issues.

Google is your friend ...

I found the solution and it's on this forum!

My Mavic and it's batteries are now OK with new firmware. Here is how I did it:

MANY, many thanks to  fans4bdce353, Beginner, United Kingdom       

"Thank you guys so much for your information, as I was worried about my drone with this problem as well. I have found another solution, & I believe it'll be the best one.
Just quickly how my problem happened, I somehow failed my first update through the app. Then, the battery had 2 LEDs Green flashed both around 13 seconds apart. I used my other two batteries from my combo package & they had no problem updating. So, I attempted to follow this forum article but no solution didn't work for me. It will always say "Battery must be 50%" everytime i tried to update even though it was prior to the failure. So this is my solution;

1) Please Download The DJI Assistant 2 application, which can be located in the Mavic Pro Download Section. Download your current computer manufacture.
2) Once you Log into the program, please connect your defective battery into  your done (Please disconnect its Gimbal Protection & Propellers just in-case) & let it initialise.
3) When the drone is booted up, connect your controller to your computer via the USB that came with the Mavic. Then, turn it on (otherwise it'll just remain in a charging state).
4) Your computer will install its relevant drivers automatically (Leave it for 1 minute).
5) Then, you will get an option to select your drone. Please do so!
6) A list will come up with all current Firmware releases from DJI, select the most up-to-date firmware & click "refresh".
7) Let the program do it's business downloading & installing. At the very end your drone will reboot along with your controller. Please don't worry if you lose connection to the program it'll return by itself!

And that was me fixed, I really hope this helps you guys! And, from now on i'll be using the computer software instead of my app! Happy flying!"

It worked perfect even though the battery was below 50%. It's now happy charging.

Thanks for your advice, seeing that mine blinks at the same rate as yours, I'll give this option a go first during the week and let you know the results.

I'm still waiting for DJI to respond on this issue, but how can you send the battery back, it can't be posted because it is still ON and can't be drained or turned off, therefore it becomes a dangerous goods in the mail system?

Hi, I had this happen. I simply put the battery back into the drone and re-ran the upgrade. It rebooted after the upgrade and everything was back to normal. Flew today with no issues.

I read this happens when a firmware update fails during the battery upgrade portion. The battery goes into a type of.. I dunno who I am or what to do. The reinstall of the latest rev even if the manic is at the latest fixed it for me.

With my update problems, I was nervous but a "refresh" of the update from the dji assistant worked.

Good luck!

The Battery issue solved/din't solve itself. After our Australian dealer requesting me to return the battery for repairs, and my asking how do you post a live battery which is a dangerous item, they have not replied at all. However the battery finally went flat, and now will not be charged, even after leaving it on the charger for 2 days. In other words it is Dead so is my $150. RIP the battery!!
