Hi, I have the fly more combo which came with 3 batteries.

suddenly early this year (january to be more exaclty) I was going to fly my mavic air and when I started preparing the drone I have realized that one of the batteries wasn't fit in the drone properly.


Then I notice the battery a little stuffed and decide to not use and seach about it, even though it turn on all the 4 green lights, I don't know if it got worst by the time even didn't charging or using but the led still go green after 3 months.

afterwards, today (03/18) I was using my drone, the battery fit perfectly and I used this battery around 15 minutes in the park in this afternoon, when I finished my flight due 30% alarm to RTH and I pulled off the battery, I found it started to stuff as you can see in the picture. now I`m afraid to use even though it still show the leds but I didn't try to charge.



Now after all this problems I just have one battery left.

Aloha pvzzin,

     Unfortunately, those batteries are now a liability and should not be used.  My experience with bulging batteries has been with Phantoms, not good.  In my case, the bulging came from keeping the batteries fully charged so I could fly all the time.  I have since learned that your batteries should be topped off before a flight or the night before.  Store batteries with a 40-60% charge.



Aloha and Drone On!

I am sorry for the issue. Please don't continue using these batteries.
May I know when did you purchase the drone? If the batteries are under the warranty period, please kindly contact our support via email support@dji.com for further assistance.
And to ensure the battery maintenance, we suggest that you store it at 40~65% power if you are going to have a long time not using it. Totally discharge and charge the battery at least once every 3 months. Thank you. Below's the link about the intelligent battery, just for your information. Thank you for your attention.

You also need to fully discharge and then charge the batteries every 3 months regardless. It's in the DJI manuals. This calibrates the battery with its Watt hour storage %

Actually I had another issue before and you guys asked to call a U.S number which I couldn't reach.

I always use the batteries to 30% and automatically it return to home after that I don't recharge the battery unless I will soon.

So I think my problem isn't how I keep the batteries but maybe the hot weather in my city with makes 32 degrees Celsius = 90F or more the hole year.

The city is called Fortaleza - Brazil

The ideal storage temperature for battery is 22 to 28°C. Sorry about this, you may dispose of the battery properly.

nothing to do here so? the storage was under 28ºc.

I tested on my apartment, the battery goes between 32-38ºc In the ground. not in the air, only turning the drone on and starting the propellers.
