Anyone know where I can purchase new OEM mavic 2 pro batteries? I just bout one from the DJI store on Amazon - it was fulfilled by Airoka and was DOA when it arrived today. I checked with DJI and they were able to run the serial number and could see that it was forst activated in 2018. Further question: I'm terrified of non-OEM batteries. Anyone have good experiences with any of the 3rd party batteries on Amazon>
