DJI makes most of the camera drones you'll find used, and most of what can go wrong with one isn't in the listing title. Newer DJI drones bind to the owner's account, the line is split between two apps, and each model pairs only with certain controllers. Here's what to sort out before you pay, using DJI's own words where it matters. For general condition checks, see how to check a used drone.
Account binding and unbinding
DJI's newer drones can be bound to a DJI account in the DJI Fly app, under Profile, then Device Management. DJI says binding means "the owner of the account has ownership of the aircraft," and a second step binds the controller to the drone. DJI pushes owners to do both, because without binding they can't file a flyaway report under DJI Care Refresh.
DJI's binding guide covers its DJI Fly drones, including the Mavic 3 Pro, Mavic 3, Air 3 and Mini 4 Pro. Unbinding has to come from the seller. DJI's steps are to log in with the bound account, connect the app to the drone and controller, tap "Remove Device from Account" in Device Management, then confirm. Nothing in that guide gives a buyer a way to do it without the seller.
So what does a still-bound drone mean for you? DJI's Care Refresh terms say "the settings of the associated account directly affect the control and use of the product," and that "the product can be connected to and used by anyone after the associated account is removed." Ask the seller to unbind it before it ships, and ask for a screenshot of Device Management once it's gone. The Mavic 2 Pro and Phantom 4 Pro V2.0 fly on DJI GO 4 and aren't in DJI's binding guide, and we found no documented account lock for either.
DJI Care Refresh doesn't move with the drone
Plenty of listings mention DJI Care Refresh, DJI's paid replacement plan. DJI's terms of service say "DJI Care Refresh cannot be transferred after purchase." The same terms say the plan and the product "must be purchased from the same country or region." Don't pay extra because a listing says a plan is included.
Buying a new plan for a used drone is limited too. DJI's FAQ says a first purchase needs a "brand new and un-activated product" or an "aircraft product activated within 48 hours," and otherwise points you to video verification or DJI support. Flyaway cover also depends on binding. DJI says it "cannot be used if the flyaway aircraft was not bound with the account and remote controller, or if the account or remote controller was unbounded before the flyaway occurred." If a plan matters to you, ask DJI with the serial number before you count on it.
DJI Fly or DJI GO 4
DJI runs two flight apps, and each drone works with only one. DJI Fly flies the Mavic 3 Pro, Mavic 3, Air 3 and Mini 4 Pro. DJI GO 4 flies the Mavic 2 Pro and Zoom and the Phantom 4 series except the RTK, along with older models. DJI still lists both for download and hasn't marked either as no longer updated.
On an iPhone, both are in the App Store. On Android, DJI's download page offers the current versions as APK files from DJI's own site, and its Google Play listings lag far behind, so get the app from DJI. Controllers with their own screens, such as the DJI RC, DJI RC Pro and DJI RC 2, come with DJI Fly already installed.
The older drones got firmware as recently as November 2023, when DJI released Remote ID updates for the Mavic 2 Pro and Phantom 4 Pro V2.0. Both need DJI GO 4 v4.3.60 or later, or DJI says "the aircraft cannot be used." DJI also warns not to install them if you fly with its GS Pro mapping app.
Which controller works with what
DJI controllers aren't interchangeable, so check the one in the photos against this list, taken from DJI's compatibility pages and firmware notes.
- Mavic 3 Pro. DJI RC (the base kit), DJI RC Pro or DJI RC-N1.
- Mavic 3. DJI RC-N1 (standard), DJI RC Pro (Cine) or DJI RC.
- Air 3 and Mini 4 Pro. DJI RC-N2 or DJI RC 2, plus the DJI RC-N3 and DJI RC Pro 2 after firmware updates in 2024 and 2025.
- Mavic 2 Pro. The Mavic 2 remote controller it came with, or the DJI Smart Controller.
- Phantom 4 Pro V2.0. The V2.0 remote (GL300L) for a phone or tablet, the Pro+ V2.0 remote (GL300K) with a 5.5-inch screen, or the DJI Smart Controller.
Two mix-ups catch buyers. The RC-N1 and DJI RC from the Mavic 3 family aren't on DJI's lists for the Air 3 or Mini 4 Pro. And the original 2016 Phantom 4 Pro used DJI's Lightbridge link, while the V2.0 uses OcuSync, so an older Phantom remote isn't a V2.0 remote. Phone-holder controllers also need the right cable for your phone, which is easy to lose.
Batteries, cycles and swelling
Batteries are the part most likely to be tired on a used DJI. In DJI Fly, the battery page shows "battery cell status, serial number, and number of times charged." DJI's manuals for the Mavic 3 Pro and Mini 4 Pro say each battery "is rated for 200 cycles" and don't recommend using it after that. Ask the seller for a screenshot of that page for every battery. On a Mavic 2 Pro or Phantom, DJI GO 4's battery menu shows the warning history, so ask for that instead.
Swelling is what to look for in the photos. DJI's battery guidelines say "never use or charge swollen, leaky, or damaged batteries," and its Mavic 3 guidelines add not to use one "if it is involved in a crash or heavy impact." A good battery sits flat with tight seams. A bulge, a split seam or a battery that won't sit flush in the drone means you should pass.
How the batteries were stored matters as much as the count. DJI's batteries discharge themselves "to prevent swelling." The Mavic 3 Pro and Mini 4 Pro packs drop to 96% after three idle days and 60% after nine, and the Mavic 2 Pro's drop below 60% after ten. The danger runs the other way too. DJI says not to store a battery "for an extended period after fully discharging it," since that "may over-discharge the battery and cause irreparable battery cell damage." Ask how they were stored and whether they still charge. DJI's Mini 4 Pro manual says to fully charge each battery at least once every three months.
Remote ID by model
Every DJI here is on the FAA's Remote ID Declaration of Compliance list, but some only broadcast after a firmware update. For the rules themselves, read our Remote ID and registration guide.
- Mavic 3 Pro and Air 3. On the list, and DJI's manuals carry the FAA compliance statement.
- Mavic 3. US Remote ID arrived in aircraft firmware v01.00.0900 in November 2022.
- Mini 4 Pro. On the list, but DJI's firmware notes say US Remote ID switches on automatically only with the Intelligent Flight Battery Plus fitted. On its standard battery it weighs under 249 g, which our under 250 grams guide covers.
- Mavic 2 Pro. Added in aircraft firmware v01.00.0797 in November 2023.
- Phantom 4 Pro V2.0. Added in aircraft firmware v01.00.70.17 in November 2023.
The FAA says all drones must be registered except those under 250 g flown under its recreational exception, and any drone that's registered or required to be must comply with Remote ID. So every DJI here needs registering, apart from a Mini 4 Pro on standard batteries flown for fun, and Part 107 work needs it whatever the weight. When you register, you list the drone's Remote ID serial number. The FAA says that on a standard Remote ID drone it may be on the drone, on the controller or in a start-up menu.
