Extend the Flight Time of the DJI Matrice 400 Drone With This Tethered Power System
A new tethered drone power system from V-Line Pro promises to extend flight times and boost operational uptime for DJI’s flagship enterprise drone.

Volarious V-Line Pro
While DJI is still facing a potential drone ban in the United States, which has caused the company to not launch its new Mavic 4 Pro in the US just yet, DJI is finding success with its many other products.
One of the big success stories for DJI this year so far has been the popularity of its new flagship enterprise drone, as the DJI Matrice 400 is proving to be a highly capable enterprise option for those looking for surveillance, inspection, and mapping services.
And while the DJI Matrice 400 (M400) is certainly quite capable at launch, a new company is set to push the Matrice 400’s flight times and operational uptime to new extremes. Here’s what you need to know.
Introducing the Volarious V-Line Pro
Created by the Singapore-based company Volarious, the new V-Line Pro is a tethered drone power system designed specifically for the DJI Matrice 400. The V-Line Pro promises to extend flight times and boost operational uptime for this flagship enterprise drone from DJI.
“This time we worked closely with DJI to ensure maximum compatibility between the drone and tether kit. The V-Line Pro eliminates the need for battery swaps mid-mission, enabling professionals to maximize payload usage and operational duration.” — Weiliang, CEO of Volarious.
Volarious shares that the V-Line Pro was developed in collaboration with DJI and should offer a simple and easy integration with the drone’s interface and systems. And while the V-Line Pro offers many upgrades, so to speak, the main improvement offered is the elimination of battery swaps during longer missions.
Volarious V-Line Pro Key Features
The DJI Matrice 400 is already capable of some stellar specs, including the ability to carry seven payloads simultaneously, but this V-Line Pro is set to include the following feature upgrades.
- 70-meter aviation-grade tether
- Smarter tension system
- Quicker setup
- Complete DJI Pilot 2 integration
Volarious shares that the V-Line Pro also offers Advanced Thermal Control, which makes use of six sensors and nine fans to further help manage and monitor the system temperature and operability.
