What Is the G35-M30 Tethered Power Station?
The G35-M30 is a professional tethered power system designed specifically for the DJI Matrice 30 and Matrice 30T industrial drones. It solves the single biggest limitation of multirotor UAVs: flight time. While a standard Matrice 30 battery delivers roughly 40 minutes of flight, the G35-M30 keeps your drone airborne for 24 hours or more — without landing, without battery swaps, without interruption.
The system uses 850VDC high-voltage transmission through an ultra-thin, lightweight cable. This isn’t just about endurance — it’s about enabling entirely new mission profiles that were previously impossible with battery-only drones.

How It Works: Ground Module + Air Module
The G35-M30 consists of two main components:
Ground Module — Houses the AC/DC transformer, cable drum with servo-controlled retraction, communication unit, and main control system. Plug it into any standard AC outlet (or generator) and it converts wall power to 850VDC for transmission up the tether.
Air Module — A lightweight DC/DC converter mounted on the drone that steps 850VDC down to the stable voltage the Matrice 30’s systems and payloads require.
The critical innovation is the AI-powered speed and torque control system. Traditional tethered systems suffer from cable collapse, oscillation, and “jerking” that destabilizes the drone. The G35-M30’s servo system actively manages cable tension at up to 5 meters per second, eliminating these issues entirely.
Why 850VDC Matters
High voltage means low current for the same power delivery. Lower current means a thinner, lighter cable. A thinner cable means less wind resistance and less weight the drone has to fight against. This is why the G35-M30 can reach 110 meters with a cable that’s still practical to spool and manage — far more usable altitude than lower-voltage tethered systems.
Real-World Applications
The G35-M30 opens up mission profiles that simply aren’t feasible with battery power:
With compatible payloads — gimbal cameras, floodlights, searchlights, loudspeakers, and light display modules — the platform becomes incredibly versatile.
Setup and Operation: No Tethered Experience Required
One of the strongest selling points of the G35-M30 is how easy it is to operate. Unlike older tethered systems that required manual cable management, tension knobs, and pre-flight cable deployment:
Simply power on the ground station, launch the drone, and the AI servo system handles everything automatically.
G35-M30 vs G35-M400: Which One Do You Need?
UAVMODEL offers two tethered solutions in the G35 series:
| Feature | G35-M30 | G35-M400 |
|---|---|---|
| Compatible Drone | DJI Matrice 30/30T | DJI Matrice 350/400 |
| Max Cable | 110m | 55m |
| Price Range | $7,130-$7,490 | $7,490 |
| Best For | Mid-size industrial ops | Heavy-lift enterprise ops |
If you’re flying a Matrice 30 or 30T, the G35-M30 is purpose-built for your aircraft. There’s no reason to adapt a system designed for a different airframe.
Bottom Line
The G35-M30 isn’t just a battery replacement — it’s a capability unlock. If your operations involve any scenario where “the drone needs to stay up there,” this system pays for itself in eliminated downtime and expanded mission scope.
