I have a DJI Phantom 4 Advanced and would like to buy an extra battery or 2.  Are the batteries the same between all the Phantom 4's ?  Or, must I buy a battery specifically for Phantom 4 Advanced?

Thought I'd learn a little bit by buying a used Phantom.  Now, barely treading water getting deeper and deeper into these quality drones

Appreciate tips on the batteries,
Regis

Hello and good day Regis. Thank you for reaching out and for the inquiry. The DJI Phantom 4 Intelligent Flight Battery is compatible with all the DJI Phantom 4 Series Drones. In addition I will be posting a link where in you can check the overview, the specifications and where you can purchase the said Intelligent Flight Batteries. Thank you.

Batteries are the same but my advice is to buy low capacity batteries since they costs much less than the high capacities and those 4 minutes of juice don’t justify the gap in price considering batteries and from are old but the prices didn’t change at all!!
I did in part the same and saved money for a car charger!
