Volarious V-Line Pro Tether Kit for Autel EVO Max 4T

Product Overview

The Volarious V-Line Pro Tether Kit for Autel EVO Max 4T is a professional tethered power solution designed to enable extended, continuous drone operations without the need for frequent battery replacements. Engineered for demanding applications such as public safety, law enforcement, emergency response, security surveillance, and industrial monitoring, this advanced system supplies consistent power to a compatible Autel EVO Max 4T drone through a lightweight, aviation-grade tether cable.

Featuring a maximum tether length of 70 meters (230 feet), an intelligent cable management system, and a dedicated drone power module, the V-Line Pro helps operators maintain an elevated aerial viewpoint for extended periods. This makes it an effective solution for persistent situational awareness, real-time observation, and mission-critical operations where uninterrupted aerial coverage is essential.

The compact, portable design supports rapid deployment and practical transportation, making the system suitable for mobile response teams and field operations. By minimizing battery-change interruptions, the V-Line Pro helps improve operational efficiency and allows personnel to focus on monitoring developing situations and coordinating responses.
