Hi guys.

I am from Austria and I flying to San Francisco on March the 26th. I own a Mavic Air, however I only have 1 battery because there are no batterys available in any shop in Austria nor in Germany. Therefore, I have to buy batteries in the states. Do you guys have any recommendations? Are batteries available anywhere in California? Thanks!

I recommend Advexure - But they are down in L.A. But give them a call anyways, maybe they can help you.

Hi there, maybe you can try to find a local store nearby at this page: https://www.dji.com/where-to-buy?site=brandsite&from=footer

djistoreoc are a good bunch from LA, I am doing the same and they are sending batteries to my hotel

I'm also in Europe and decided not to wait and just order from DJI directly a few days ago. Batteries are scheduled to arrive this tuesday and when you order 2 or more shipping is free anyway. Saves me a lot of hassle ;)

Hi leichti I'm also from Austria (but I live in Florida)
Try this store:
DJI AUTHORIZED RETAIL STORE
735 Montgomery Street, Suite 112,San Francisco, CA 94111
(415) 757 0394

Some Apple stores have the combo in stock, but I don't know if they sell batteries separately.  Might be worth a call...

Just called Drone Nerds and the guy on the phone said maybe next week.
They are in Florida.
