DJI warrants their batteries for only 6 months regardless of the extended warranty coverage you may have. (Mavic 2 Pro in my case)
Three of my four batteries, after 100-103 cycles, that were carefully monitored and only charged when cooled, resulted in puffy and cracked housings within a 7 month period. DJI refused to honor a warranty claim as it was past the timeframe allotted.
I decided to take a careful look inside to see what was going on.
Red arrows indicated cut lines to access the guts of this battery.
Red arrow indicates micro switch behind latch that secures battery to aircraft.
Battery was carefully and fully discharged before "operating". Each battery opened had a single bad cell in position #3, coincidental ? Manufacturing error? A pissed off, underpaid, overworked employee?? Or just plain bad luck? Who knows?!
This is what it looks like inside. Lots of electronics and a few micro switches. I have a better understanding of why they have outrageous prices now. Still, overpriced, but DJI has us by the horns, right?
Check your batteries before EVERY flight, be safe...have fun.
