The EVO 2 series features the longest battery life of any foldable drone (up to 40-minutes of flight time). With a top speed of 45mph and up to 9km range, you can now go further, faster. EVO 2 presents an all new sensor and storage package and omni-directional obstacle avoidance. We’re talking 12 computer vision sensors, 2 sonar sensors, and 2 LED landing lights, working together to create an aircraft with the best obstacle avoidance in the industry. EVO 2 offers failsafe features letting you know when the battery is low and when it’s time to return to home. We’ve also added 8GB of internal storage as well as the ability to accept SD cards up to 256GB. Follow subjects autonomously around obstacles at high speeds using Autel’s patented Dynamic Track 2.0™ and watch as AI technology creates smart flight paths in real time. Dual-core powered object detection recognizes up to 64 subjects at once including people, vehicles, and animals.
The EVO II Pro Enterprise comes with the Loud Speaker, Spot Lights and Strobe.

This allows the EVO Max 4T's onboard Autel Autonomy Engine to perceive objects down to 0.5 inch, eliminating blind spots and enabling operation in low light or rainy conditions.
Binocular Vision System
Millimeter Wave RadarA-Mesh 1.0The Drone Industry's First Mesh Networking TechnologyEVO Max 4T features the new A-Mesh system, enabling drone-to-drone autonomous communication, connection, and collaboration.
Strong Anti-Interference
The EVO Max 4T can communicate seamlessly with other drones in the vicinity, unlike a traditional chain structure. If a single drone fails or exits unexpectedly, the entire system will independently self-organize and continue to relay critical information.
Beyond-Line-of-Sight Applications
With A-Mesh, multiple aircrafts in the vicinity can act as relay points to greatly improve BVLOS operation effectiveness.
Full-Fleet Control
Multiple drones can be controlled autonomously by 1 pilot or by a group of pilots simultaneously with or without LTE coverage.
Enhanced Range
Communication nodes can be placed statically on hills or poles to provide full coverage to an area, or a swarm of drones can provide mobile communication points to extend the coverage of the entire group.
Autel SkyLink 3.0
The EVO Max 4T SkyLink 3.0 system comes with 6 antennas, 4 frequency bands, AES-256 encryption*, and optional 4G integration* to provide users with the most advanced flight capabilities ever in an EVO.
