DJI Mini 4 pro/Mini 3 Series Intelligent Flight Battery Plus
The DJI Mini 3 Series Intelligent Flight Battery is the standard (non-Plus) flight pack for the DJI Mini 3, Mini 3 Pro, and Mini 4 Pro. It is a 2453 mAh, 7.38 V Li-ion pack rated at 18.1 Wh that keeps these airframes under the 250 g class weight, the regulatory threshold that exempts the aircraft from FAA recreational registration and supports Part 107 Category 1 Operations Over People. Each pack delivers up to approximately 34 minutes of flight time and weighs roughly 80.5 g.
Standard flight battery for the DJI Mini 3, Mini 3 Pro, and Mini 4 Pro. 18.1 Wh, ~80.5 g, keeps the aircraft under the 250 g class.
Features
- Standard flight battery for the DJI Mini 3, Mini 3 Pro, and Mini 4 Pro: same pack across all three airframes, so a single spare-battery inventory covers a mixed Mini fleet
- Keeps the aircraft under 250 g: with this battery installed, the Mini 3, Mini 3 Pro, and Mini 4 Pro stay in the sub-250 g class that exempts the aircraft from FAA recreational registration and supports Part 107 Category 1 Operations Over People
- 2453 mAh, 7.38 V, 18.1 Wh Li-ion chemistry, sized for the Mini airframe's compact battery bay
- Up to approximately 34 minutes of flight time per pack (DJI lab data; varies slightly by airframe and conditions)
- Charges in approximately 64 minutes from a DJI 30 W USB-C Charger connected directly to the aircraft, or approximately 56 minutes in the DJI Mini 3 Pro / Mini 4 Pro Two-Way Charging Hub
- Max charging power of 37 W: works with any USB-C Power Delivery charger at that wattage or higher
- At 18.1 Wh, well under the FAA / IATA 100 Wh threshold for spare lithium batteries in passenger carry-on, with no special airline approval required

Who this is for
- Mini 3, Mini 3 Pro, or Mini 4 Pro pilots who want a spare battery on hand to extend a day of flying without waiting on a charge
- Operators who specifically want to keep the aircraft under 250 g, either to avoid FAA recreational registration or to fly Part 107 Category 1 Operations Over People without a parachute or impact-energy testing
- Travelers who fly the Mini to job sites or vacation by commercial air and need a flight battery that sits well under the 100 Wh airline threshold
- Fleet operators standardizing on the standard (non-Plus) battery across a mixed Mini 3 / Mini 4 Pro fleet, so spares and charging hardware stay common
What's included
- 1 × DJI Mini 3 Series Intelligent Flight Battery (standard)
Please note: This is the standard (non-Plus) Intelligent Flight Battery for the DJI Mini 3, Mini 3 Pro, and Mini 4 Pro. The Intelligent Flight Battery Plus is a higher-capacity option (3850 mAh, 28.4 Wh) that extends flight time but pushes the aircraft over 250 g. If you specifically want the sub-250 g class advantage, use this standard battery. If you prioritize flight time over the 250 g threshold, look for the Mini 3 / Mini 4 Pro Intelligent Flight Battery Plus instead. The aircraft and any chargers are sold separately.
FAA registration: In the United States, drones flown for recreational purposes that weigh less than 250 g (0.55 lb) are exempt from FAA recreational registration under the FAA Reauthorization Act / 49 USC § 44809. Drones flown under Part 107 (commercial) must be registered regardless of weight. Installing this standard battery on the Mini 3, Mini 3 Pro, or Mini 4 Pro keeps the aircraft in the sub-250 g class; installing the Plus battery pushes it over and triggers the registration requirement for recreational flight.
Travel and shipping: At 18.1 Wh, the Mini 3 Series battery is well under the FAA / IATA 100 Wh threshold for spare lithium batteries in passenger carry-on. Airlines treat sub-100 Wh packs as standard carry-on items, typically allowing up to 20 spares per passenger without special approval. Spare lithium batteries are not permitted in checked baggage. Carry packs with terminals protected against short-circuit.
FAQ
Which Mini drones does this battery fit?
The DJI Mini 3, the DJI Mini 3 Pro, and the DJI Mini 4 Pro. It is the same standard flight pack across all three airframes. It is not compatible with earlier Mini models (DJI Mini, Mini SE, Mini 2, Mini 2 SE), which use a different battery, and it is not compatible with the DJI Avata or other non-Mini airframes.
How is this different from the Plus battery?
The standard battery (this product) is 2453 mAh and 18.1 Wh and weighs about 80.5 g, keeping the aircraft under the 250 g class. The Plus battery is 3850 mAh and 28.4 Wh and weighs about 121 g, which pushes the aircraft over 250 g but adds roughly 13 to 17 additional minutes of flight time depending on the airframe. Pick this standard battery if the 250 g class threshold matters to you (recreational no-registration or Part 107 Category 1 OOP); pick the Plus if you'd rather have the extra flight time.
How long does each battery fly?
Up to approximately 34 minutes per pack, per DJI's published lab data. Actual flight time varies slightly across the three compatible airframes (the lighter Mini 3 typically squeezes out a couple of extra minutes vs. the Mini 3 Pro and Mini 4 Pro), and shorter in real-world conditions with wind, cold, or aggressive flying.
How do I charge it?
Two ways. You can leave the battery in the aircraft and connect a DJI 30 W USB-C Charger (or any USB-C PD charger of at least 30 W) directly to the aircraft's USB-C port; that takes approximately 64 minutes per battery. Or you can remove the battery and put it in the DJI Mini 3 Pro / Mini 4 Pro Two-Way Charging Hub, which takes approximately 56 minutes per battery. The charger and the hub are sold separately.
Does this battery affect the aircraft's weight class for FAA registration?
The standard battery (this product) keeps the Mini 3, Mini 3 Pro, and Mini 4 Pro under the 250 g (0.55 lb) FAA recreational registration threshold. Drones flown for recreational purposes under 250 g are exempt from FAA recreational registration. Drones flown commercially under Part 107 must be registered regardless of weight. The Plus battery pushes the aircraft above 250 g and triggers the recreational registration requirement.
Can I take it on a commercial flight?
Yes. At 18.1 Wh, this battery is well under the FAA / IATA 100 Wh threshold for spare lithium batteries in passenger carry-on. Airlines generally allow up to 20 sub-100 Wh spare batteries per passenger in carry-on without special approval. Spare lithium batteries are not permitted in checked baggage. Carry packs with terminals protected against short-circuit (in original packaging or with tape over the contacts) and confirm your specific airline's policy before traveling.
How long does the battery last?
Lithium battery service life depends on how the pack is used and stored. Rotate packs through partial-charge storage (40 to 65%) between deployments, avoid leaving packs at full charge for extended periods, and charge within the recommended temperature range. The Intelligent Battery firmware will self-discharge a stored pack toward a safe storage level over time. Refer to the DJI user manual for your specific aircraft for the manufacturer's recommended storage interval.
How should I store the battery between flights?
For short periods between flights, store at room temperature out of direct sunlight. For longer storage (more than 10 days), discharge each pack to approximately 40 to 65% before storing. The Intelligent Battery firmware will self-discharge a stored pack toward a safe storage level over time. Avoid storing at full charge or fully discharged for extended periods.
