Product Description

Long Time Flight Tether System for DJI Drone Used by Cleaning, Inspection, Public Security

 

1. Typical characteristics

1). Small in size, light weight, backpack storage, easy to carry, with a tethered box weighing only 8.5kg.

2). Air module power supply 980g< single TB60 battery 1350g, safe replacement and non-destructive mounting.

3). Replace a battery without changing any structure of the drone, and seamlessly switch between tethering mode or free flight mode.

4). The operation is simple, and the entire process of unmanned aerial vehicle takeoff and landing does not require the operation of the mooring box, truly automatically reel in/out.

5). The air module power supply has a constant voltage output, and the backup battery has no charging or discharging phenomenon throughout the entire process, without losing power or causing hidden damage.
