The T50 batteries can be charged in the field with the D12000iEP Multifunctional Inverter Generator which employs the cutting-edge EFI technology. It offers a significant fuel saving of 15%, thereby enhancing the fuel economy. This means you can trust in the efficiency of your charging process, reducing wait times and energy use.


On the other hand, the T25 comes with the DB800 Intelligent Flight Battery with a capacity of 15.5 Ah. Utilizing the D6000i Multifunctional Inverter Generator, it can also achieve the same ultra-fast charging time of just 9 minutes. 




Orchard Operations and Terrain Following

Orchard farming comes with its own set of challenges, tackled head-on with the optional Orchard Kit. This accessory expands the T50 and T25's spraying flow rate to 24 liters/min. This enhancement significantly broadens the spray coverage and doubles the droplet count on the backside of leaves in fruit tree interiors. 




For orchard operations, the drone's safety systems, including dual Active Phased Array Radar and dual binocular vision sensors, ensure safe navigation of rugged terrain. They can automatically detect and bypass obstacles they might encounter.




Equipped with active phased array radar and dual-vision systems, the T50/T25 can execute aerial surveys on slopes with a maximum gradient of 50°. It can automatically identify fruit trees and obstacles, generating precise autonomous 3D operation routes based on the distribution trends of fruit trees. With its ability to perform Terrain Following on slopes up to 50°, it caters to the vast majority of orchard operational needs.





Revamped Propulsion System


Building upon the foundation laid by its predecessor, the T50 propeller's outer diameter has been increased to 54mm, bolstering the bending and torsion resistance by an impressive 27%. Its new high-strength propeller blade is designed to withstand deformation, ensuring a safe and reliable operation. With high-power Electronic Speed Controllers (ESCs), the T50 not only provides superior heat dissipation but also a more robust through-flow capability, resulting in a stable and dependable power output.


Adding another layer of safety, the T50 and T25 arms now come with upgrade safety locks that must be secured before takeoff. This ensures further protection, thereby enhancing the operational safety of the drone.
