Volarious V-Line Pro: Uninterrupted Power for the DJI Matrice 400 series

The Volarious V-Line Pro Tether Kit with the Matrice 400 Series Power Module is the ultimate “force multiplier” for professional drone operators. By connecting the DJI Matrice 400 to a continuous ground power station, you transform a mobile platform into a permanent aerial station. This system eliminates the biggest limitation of modern drone operations: battery life. Whether observing for hours during disaster relief, monitoring large-scale infrastructure or securing critical sites; the V-Line Pro guarantees that your “eye-in-the-sky” stays exactly where it is needed, without interruptions for landings or battery changes.

Dynamic Response & Advanced Monitoring

The system is designed not only to power the drone, but also to ensure its freedom of movement and stability:

• 70 metres Aviation-Grade Tether: The ultra-light, reinforced cable provides an operational altitude of up to approximately 70 metres. The cable is specifically designed to provide minimal air resistance, allowing the drone to maintain its position with extreme precision.
• High-Speed Smart Reel: With an impressive deployment and retrieval speed of as much as 7 m/s, the winch responds instantly to drone movements or sudden gusts of wind. This minimises slack (cable slack), which is crucial for stable flight and preventing entanglement.
• Seamless Software Integration: Operators can monitor all critical data-such as cable voltage, temperature and power status-directly via the V-Assist app or via a dedicated widget in the DJI Pilot 2 interface. This provides a centralised overview without having to switch between different screens.

Industrial Reliability & Fail-Safe Architecture

The build quality of the V-Line Pro meets the strictest aviation and industry standards:

• Dedicated Matrice 400 Power Module: The included module safely converts the high voltage from the tether unit to a stable on-board voltage. The module acts as an intelligent bridge and contains a backup battery, allowing the drone to always return to base safely and in a controlled manner in the event of a power failure on the ground.
• Active Thermal Protection: The ground unit is equipped with multiple temperature sensors and powerful fans. Combined with overcurrent and short-circuit protection, this ensures safe operation even during missions lasting days at a time under harsh atmospheric conditions.
• Aviation-Grade Components: Every component, from the connectors to the internal coil, has been selected for durability and minimum wear and tear under intensive professional use.

Why the V-Line Pro is indispensable

For organisations operating in emergency response, border control or large-scale industrial inspections, the Volarious V-Line Pro offers a strategic advantage. The ability to keep a drone in the air indefinitely means that precious minutes are not lost to repeated takeoffs and landings. With the V-Line Pro, you choose maximum operational continuity, higher data density and the assurance that your drone is always on standby when every second counts.
