Extending DJI M30 Battery Life: The Tethered System Solution

In the world of drones and unmanned aerial vehicles (UAVs), one of the biggest challenges has always been maximizing the battery life of each drone during demanding missions. While carrying multiple batteries is a common solution, there is another option: the tethered system. This article explores the advantages and use cases of tethered systems for extending the battery life of drones, with a focus on the DJI M30.

Bringing Multiple Batteries

Carrying a substantial number of drone batteries to a mission site is a common practice, but it can come with its own set of challenges. The primary advantage of this method is its cost-effectiveness. Plus, the drone remains free to fly and observe the mission scene. However, it's not without disadvantages. The most significant downside is the potential downtime, which could occur at a crucial moment when continuous surveillance is needed. This is where tethered systems step in to address these limitations.

The Tethered System Solution

Using a tethered system offers unlimited battery life for your drone. With this innovative approach, you can fly your DJI M30 continuously without worrying about downtime, ensuring you capture every scene from start to finish. Here's how it works:

To use the tethered system, you need your DJI M30 drone, the tether system itself, and a compatible generator. Connect the tether system to your drone and generator. Once it's linked up, you can hover in the air for as long as the generator has power.


The key component of this solution is the V-line Pro tether system, which offers more than just a simple tethered connection. It includes a range of advanced features that set it apart from the competition:

  • Automated Reel Tension: The system maintains the appropriate tension on the tether, ensuring a stable connection.

  • Auto Land and Auto Takeoff: These features make operating your tethered drone hassle-free.

  • Industry Leading Ascent Speed: Adjust the ascent speed to suit your mission's requirements.

  • Software : Vehicle Mode (vehicle following mode for DJI M30)

  • Hardware : V-Light (A powerful 20,000-lumen floodlight for enhanced visibility during night operations)

Use Cases for Tethered Systems
Tethered systems have a wide range of use cases, making them suitable for a variety of applications. These include, Big Events for capturing breathtaking aerial footage and providing security at large gatherings. Border Patrol to ensure continuous surveillance of critical border areas without the need for battery swaps. Emergency Response, offering uninterrupted aerial views during critical emergency situations. Search and Rescue in providing extended flight time for locating missing persons or assessing disaster-stricken areas, and many more.

Flexibility and Freedom

One of the notable benefits of using V-Line Pro tethered system is that it does not modify the drone itself. If the need arises to switch back to free flying mode, simply detach the tether lines, and your DJI M30 is ready to soar.

In conclusion, tethered systems, such as the V-line Pro, have revolutionized the way drones like the DJI M30 can be utilized. They offer unlimited flight time, which is a game-changer for missions where continuous observation is crucial. This innovative solution ensures that no crucial moments are missed, making it a vital tool in various fields, from security to emergency response and many more.
