After less than 2 years and 86/87 cycles, 2 batteries have inflated. I have another 2 (not enough ) Mavic is with 425 flights ~80h air time and 2300 km!
I need advice - If You were in my place what Youll do:
1. Buy 2 (1?) bat for Mavic pro (what if Mavic fails soon?)
2. Buy Mavic 2 pro with fly more (Price is a bit high for my liking )

At the current price of the mavic pro batteries i would just replace the 2, as long as the drone is still flying fine should be no need to fork out a whole lot more to upgrade because 2 batteries packed up
