DJI Dock 4 swaps drone batteries in 25 seconds, and skips the US market

DJI has launched Dock 4, the first of its drone docks that swaps an aircraft's battery automatically instead of recharging it in place, alongside a new aircraft built for it called the DJI Matrice 5TD. The Shenzhen manufacturer announced both on 14 October 2026. DJI puts a swap at under 25 seconds; DroneXL reports a full landing-to-takeoff turnaround of 45 seconds, where a dock that recharges the pack in the aircraft needs roughly half an hour.

What the dock actually changes

A drone-in-a-box station is a weatherproof enclosure that launches, lands, shelters and recharges an aircraft without anyone on site. The limiting factor has always been the recharge: once the aircraft lands, the site is uncovered until the battery is full again. Dock 4 removes that gap by taking the depleted pack out and fitting a charged one.

DJI's specification sheet gives the dock four battery compartments, of which three may hold packs — the swap mechanism needs one slot free to work. Two packs charge at a time, each from 15 per cent to 95 per cent in about 27 minutes at 25 °C. DroneXL reports that a returning aircraft is given a fresh pack whenever it lands below 79 per cent, and that each pack can run the dock itself for about four and a half hours during a mains outage.

The enclosure weighs about 66 kg without the aircraft or the compartment batteries, is rated IP56 and operates from −40 °C to 50 °C, with self-preheating batteries in the cold and air conditioning in the heat. Maximum operating radius is 10 km. heliguy notes that the video link, RTK base station and dual 4G connectivity all sit in a separate DJI O4 Ground Station, an optional accessory on Dock 3 and a requirement here.

The aircraft: DJI Matrice 5TD

Dock 4 flies only the Matrice 5TD, so an operator running the earlier Matrice 4TD cannot move an existing fleet into the new enclosure — although DroneXL notes the dock keeps the 400 × 400 mm mounting pattern of Dock 3, so prepared groundwork is reusable.

DJI lists the aircraft at 2,600 g with battery, propellers and memory card, 3,050 g maximum take-off weight, rated IP55 and operating from −40 °C to 50 °C. Maximum flight time is 59 minutes in laboratory conditions with no payload and no wind; maximum horizontal speed is 21 m/s in automated FlyTo tasks and 15 m/s in every other mode. Take-off, landing and flight are rated to winds of 12 m/s, and up to 450 g of accessories can be carried across three mounts — heliguy identifies these as the AL2D spotlight, the AS2D speaker and the AP1 parachute.

The sensor package is where the step up from the Matrice 4 Series is clearest. The 5TD carries three 50 MP visible-light cameras — wide, medium telephoto and a 252 mm-equivalent telephoto DJI credits with resolving detail at 400 m — a 1,280 × 1,024 thermal sensor with a 2,560 × 2,048 high-resolution mode, a laser rangefinder good to 3 km and a near-infrared illuminator for night work. Obstacle sensing combines vision, 3D infrared, rotating LiDAR and three-direction millimetre-wave radar, and onboard AI recognises 17 object types in real time against three on the previous generation. DJI also describes a Flight Termination System kept separate from the flight controller, which it presents as a requirement for European C6 class marking.

Why US operators will not see it

DJI's own specification page lists the aircraft's transmission range under the Canadian (IC), Chinese (SRRC) and European/Japanese (CE/MIC) regimes — 40 km, 25 km and 12 km respectively — and gives no figure for the United States. DroneXL reports the same absence across the dock's transmitter table, where Dock 3 lists FCC power on every band.

That is consistent with the two US measures this site has tracked. The FCC's December 2025 Covered List action, covered in our piece on what the Covered List has done to US drone availability, blocks new equipment authorisations for foreign-produced drones, which is why recent DJI models have launched everywhere else first. The second is narrower: the proposal in FCC docket 26-189 would bar the import and marketing of covered foreign drones with capabilities the bureaus class as military-grade, and DRONELIFE records thermal imaging, integrated LiDAR and docking stations among the named categories. The Dock 4 and Matrice 5TD combination has all three. Comments closed on 2 September 2026 and nothing has been adopted.

DJI has published no price and sells the system through authorised enterprise dealers. Outside the United States the 5TD sits between DJI's compact enterprise line and its heavy-lift platform, the Matrice 400, which is rated to a 6 kg payload and the same 59-minute flight time but is flown from a controller rather than a dock. Inside the United States the comparison is moot.

Frequently asked questions

Can a Matrice 4TD fleet use Dock 4?

No. DJI lists the Matrice 5TD as the only compatible aircraft. The dock does reuse the 400 × 400 mm mounting pattern of Dock 3, so a prepared site does not have to be rebuilt.

Does the dock keep working in a power cut?

Partly. DroneXL reports that with at least two packs loaded the dock can still swap and launch, but it cannot charge until mains power returns; each pack runs the dock for about four and a half hours.

Is Dock 4 available in the United States?

DJI's specification sheet lists no FCC transmitter data for either the dock or the aircraft, and no US price has been published. Both of the FCC measures described above would have to be resolved before a US route existed.

Can the Matrice 5TD be flown by hand?

It is built for automated docked missions. heliguy reports that a firmware update due at the end of October 2026 adds support for the DJI RC Plus 2 as an emergency controller for basic flight and live video.
