No, the DJI Mini 3 isn't under 250 g with the Battery Plus. DJI says it weighs about 290 g with the Intelligent Flight Battery Plus, so in the US you must register it with the FAA even for hobby flying. In return you get up to 51 minutes of rated flight time instead of 38. It's worth it if you're already registered or fly under Part 107; if you chose the Mini 3 to skip registration, stick with standard batteries.

What changes when you use the Plus
Registration. At about 290 g, the drone is over the FAA's 250 g line. Register it at FAADroneZone ($5, 3 years) and mark the number on the drone. See FAA registration.
Remote ID. DJI's manual says the Mini 3's Remote ID broadcast is only activated with the Battery Plus. With the Plus fitted, it meets the FAA's Standard Remote ID rule on its own. With the standard battery, it doesn't broadcast. See Mini 3 Remote ID.
Performance. More flight time, but a heavier drone. DJI cuts the maximum takeoff altitude to 3,000 m and says not to mount propeller guards or third-party accessories with the Plus, to avoid losing propulsion.
Europe. The Mini 3 is a C0 drone only with the standard battery, and DJI doesn't sell the Plus in Europe.
Who should buy it
- Part 107 pilots. Your drone must be registered anyway, and it must broadcast Remote ID. The Plus turns on the built-in Remote ID, so you don't need a separate broadcast module.
- Registered hobby pilots who want longer flights for sunsets, hikes or mapping a property.
- Not for anyone who chose the Mini 3 to avoid registration.
You can carry both. Register the drone, fly standard batteries when you like, and switch to the Plus for long sessions. The registration covers the drone either way.
Charging the Plus
With DJI's 30W USB-C charger, the Plus takes about 101 minutes in the drone or 78 minutes in the two-way charging hub. The Mini 4 Pro / Mini 3 Two-Way Charging Hub lists Mini 3 series Plus batteries as compatible. At 28.4 Wh, it's far under the 100 Wh airline limit; spares go in carry-on. See Mini 3 charge time.
Availability
DJI says the Plus is sold separately and only in selected countries and regions. We don't stock it right now; contact us if you'd like us to check. Don't buy unbranded "high capacity" Mini 3 batteries from marketplaces. They aren't qualified by DJI and can be unsafe.
The simpler way to fly longer
If staying under 250 g matters, buy more standard batteries instead. Three standard packs give over 100 rated minutes and keep the drone registration-free for hobby use. See Mini 3 batteries and chargers and Mini 3 battery life.
