This is an informational post only. For thought.I fly a lot. I think I flew about 20 million feet (about 85% with Litchi app) with my Mavic Pro and Mavic 2 Pro.
For Mavic 2 Pro I had 14 batteries. 2 of them broke from 20 to 40 charge / discharge cycles and were replaced under warranty. 6 of them broke from 50 to 70 charge / discharge cycles. All of 6 batteries broke the same way: during the flight, DJI Go 4 displays a message that the battery is completely discharged and the drone is landing. A very unpleasant mistake if you fly over the city. Now I have given all the batteries to the service center and I'm waiting for an answer.
Now I have 6 batteries with 15 - 30 charge / discharge cycles.
For example my first drone was Mavic Pro. I had 8 batteries for it. All of them are working fine still. More than 140 charge/discharge cycles for each battery.
