Adaptive drone

1). Support flight altitude: 30-50m (tethered cable 33m, 55 meters is an optional).
2). Support takeoff weight: 1-3kg
(drone power efficiency varies, this data is for reference only).
3). Support flight duration: ≥ 8h (the system can support working duration,
which depends on the structure and electrical fatigue resistance of the drone).

Functional characteristics
1). Automated cable reel in&out function: Passive wire reel out, long press the button to automatically reel in cable, and backup battery to activate cable reel in function in case of power cut off.
2). Protection function: Strong and weak current separation design. Input overvoltage and undervoltage protection. Output overvoltage, output overcurrent, output short circuit, output over temperature protection, fault elimination and self recovery.
3). Equipment portability: With a backpack design, the backpack can be equipped with a complete tethering system that includes a tethering box, onboard power supply, and other accessories. The overall weight is 5.0 ± 0.2kg. 
4). 1800W/3500Wh outdoor mobile power bank or 1200W/2.5L generator is recommended.
