There are many cases reported when Mavic 2 Intelligent Flight battery bloated up to no longer be securely fixed in a drone.
I’ve been praising Mavic 2 Zoom drone virtually all the time, and I have a real basis for doing so, you can read here.
I can’t even remember any reason to critique this great aircraft. However, nothing is perfect, and Mavic 2 Zoom and Pro drones, not exclusion, occasionally have one significant issue.
Unfortunately, one of my batteries is amongst those that can’t anymore be used for safe flying with DJI Mavic 2 Zoom drone.
By Googling the keywords “DJI Mavic 2 intelligent battery bloated, swollen or puffy,” as a result, we find relatively many articles or forum threads related to this problem.
I encountered the problem myself about nine months after I have begun using this battery.
From the beginning, I didn’t pay much attention to a small swollen at the bottom of the battery as it still could be firmly fixed into the drone. After a while, I was starting to worry a little, especially after a long flight the battery had heated up as it could not be secured to the quadcopter at all.
I tried to find a solution, but eventually, I concluded that it was a DJI issue. As far as I could see from what had been read, some of the DJI Mavic 2 Intelligent Flight Batteries produced in mid-2018 could be such a problem.
What to do?
Whether it is safe to fly such a battery without fear of being disconnected into the air and the result is unambiguous – $1.3K has been lost?
Definitely not to fly as no DJI care refresh and any other guaranty will help. It is your fault. For the sake of the truth, I have to say that I have been experimenting a little and flying such a battery from the beginning.
I tried to use the rubber bands to keep the battery safe, but later I realized it didn’t really give much more security.
There is one way to temporarily eliminate the bloat, to keep about an hour in the freezer. Low temperatures reduce gas expansion and also reduce internal cell volume. In lithium-ion batteries, gases expand as the temperature rises, but in some cases, malformations in the battery structure cause the housing deformation.
After freezing, the bloat will be gone, and the battery locks safely in the drone, but the temperature rises as we fly, and after fifteen minutes or so, the battery puffs up again. It is not safe anyway.
My conclusion is that this battery should not be used
My conclusion is that this battery should not be used. This will sooner or later lead to a break of the fuel supply during the flight. As I have already said, the results will not only be a loss of money, but it can be a real danger even to life or other damage on the ground when the drone falls.
However, The DJI, after the latest updates, has made sure that a drone does not flight with a badly attached battery. In this case, the warning appears on the console, and the drone cannot even be taken off. So, I warn again- do not experiment with “freezer way” flattened battery. It will bulge again during the flight.
Is there any way to blame manufacturer DJI on this issue and the loss of money? DJI gives the battery 6 months of warranty, but battery bloat usually occurs more than half a year later. In reality, no way, and you have to accept the loss and buy a new one.
I have read that there is a great consumer protection policy in Australia, and many are lucky to solve this problem positively. I’m glad for them, but it’s not elsewhere. Also, to my questions about this problem to the DJI customer support, I haven’t received any answers.
Recently, I was lucky to buy a new DJI Mavic 2 Intelligent flight battery for an excellent discount of €104 it about $124, and also the production date is end-2020. I hope that this will be OK.
Has this bloated battery become completely unusable? It’s not really. This DJI Mavic 2 Intelligent Flight Battery can be used as a powerful power bank. All you need to do is buy Mavic 2 Battery Charger Converter for $12
Despite this limited flaw, DJI Mavic 2 Zoom and Pro drones are still unbeatable leaders in their range, with whom it is fun to fly, film, and photograph to delight themselves and others.
