| Platform generation |
Newest DJI heavy-lift generation |
Established heavy-lift platform |
The 400 is the newer design; the 350 RTK is the proven incumbent. |
| Max takeoff weight |
15,800 g (MTOM) |
9.2 kg |
The Matrice 400 carries a substantially higher maximum takeoff mass. |
| Max payload |
Up to 6 kg (varies with altitude and battery) |
Single-gimbal damper up to 960 g |
The 400 targets heavier and combined payloads; confirm mounting for your sensors. |
| Reference flight time |
Up to 59 min (DJI test conditions) |
Up to 55 min (no payload, windless) |
Both publish long endurance; payload and wind reduce real endurance. |
| Transmission |
DJI O4 Enterprise Enhanced Video Transmission |
O3 Enterprise, up to 20 km (FCC) |
Both publish enterprise transmission systems; regional limits and site interference still control the usable link. |
| Ingress protection |
IP55 with TB100 batteries (conditional) |
IP55 with TB65 batteries (conditional) |
Both publish IP55 under stated conditions. The rating is not permanent; follow the relevant DJI weather, battery and port-cover requirements. |
| Batteries / station |
TB100 batteries + BS100 Battery Station |
TB65 batteries + BS65 Battery Station |
Different battery generations; plan charging infrastructure per platform. |
| Payload ecosystem |
New-generation payloads and dual-gimbal connector |
Zenmuse H20/H20T/H20N, P1, L1, L2 |
The 350 RTK has a mature Zenmuse ecosystem; confirm 400 payload compatibility. |
| Operating temperature |
-20°C to 50°C |
-20°C to 50°C |
Published aircraft ranges match, but payload, battery and weather limits still apply separately. |
