Hello

My battery inflated during last flight !
Is it dead or is it possible toi use it again ?
What caused this problem ?
DJI will you replace it ?

thanks

Wouldn't recommend to use it again.

An expanding battery as it heats up in flight could cause it to disconnect and the drone to loose power resulting in a bad crash.

The batteries expand due to gas from electrolyte decomposition

I’m having the same problem for 4 of my 5 batteries, not even reached 2 years of use… Now I can only fly with one battery waiting for DJI answer. Very annoying.

How many cycles has it gone through?

Batteries do not last forever.  Apart from whatever service DJI may offer, you may want to develop your own practices for buying a new one once in a while and cycling the old ones out of your inventory.
