Little cracks in body battery Mavic pro

[Petje]

Today i was making a test fly, and after this I saw that there were cracks in 2 of my batteries. I didn't fly for 3 months.
The third battery does't have cracks. Is this a known problem?

Can you take more pictures? Need one for the side and back.

Were the batteries stored in a very cold or very hot place?

I storend the batteries at normal room remperature. 20 degrees. You can't see any damage on the back or side of the battery.
The cracks are only on the top of the battery.

Where do you live and how old are the batteries?

 

[Petje]

The batteries are more than a year old. I live in Holland.

Well, I think they might have puffed. That means that the battery inside might have outgrown the battery case. If it were me, I would not fly with them, but I like to be safe.

You can try to charge them and see what happens. I would charge them outside, in a well ventilated area, that is not near anything flammable, maybe in the middle of a field.

Common defect both on the aircraft (particularly the nose) and batteries after a few months even when they're in perfect condition.

Plastic is thin and the moulding must not be perfect and lead to some internal stresses that can show up after a while.

Sorry but the Mavic does not have a history of having stress cracks in the nose over time, neither do the batteries.

Any deformation in the nose of the Mavic comes like that new from the factory.

The only drone I know of that had stress cracks was the Phantom series, and the motor pods developed cracks from the vibration, over time. My easy fix was to take the motors out and lay a base of flexible adhesive, then remount the motors. Never had an issue with cracks after that.

I've seen numerous reports of this, and my friend's Mavic has it on the nose. There may have been a deformation from day one, but it only got noticed when it turned into a crack after a few months.

The proof of the pudding is in the eating. Believe half of what you see and none of what you hear. (Im waxing poetic today).

I have seen hundreds of Mavic bodies, and I can say that not a single one I have ever seen has a stress crack. Maybe your friend just got unlucky. Some of these have the deformation from the factory which I have come to get used to seeing. Never had one fail because of it.

Here are just a few from crashed drones that I keep as souvenirs. The only damage to them, even after being augered into the ground, is some bent plastic. The only damage that keeps these bodies from flying again is the broken "screw pillars" inside the cover. Once one of them is cracked, the whole body is comprised.
