New Tethering Power Supply System for Dji Drones Mavic 3 Series Good and Cheaper Than Elistair

New Tethering Power Supply System For DJI Drones Mavic 3 Series Good and Cheaper Than Elistair1. Typical characteristics1). It is small in size and light in weight, with a tethered box weighing only 3.6kg. It is easy to carry with a backpack for storage.2). Replace the primary battery, without changing any structure of the UAV, and seamlessly switch between tethering or releasing.3). The operation is simple, and the entire process of drone takeoff and landing does not require the operation of the ground module. The button type take-up function is also available.4). The onboard 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.2. Adapted to DJI Mavic 31). Support flight duration: ≥ 12h.2). Support flight altitude: ≥ 30m (tether cable 33m, reserved safety length).3). Optional lighting group: 200W (JM200).3. Functional characteristics1). Cable reel in&out function: Passive wire reel out, long press the button to automatically reel in cable, and manually winding in case of power loss. 2). Protection function: Input overvoltage and undervoltage protection, output overvoltage, overcurrent, short circuit, over temperature protection, fault elimination and self recovery.3). Fault alarm function: The system fault alarm light flashes red and beeps to alert.4). Equipment portability: With a backpack design, the backpack can be equipped with a complete tethering system that includes a tethering box, onboard power supply, lighting unit (optional), and other accessories. The overall weight is 5.0 ± 0.2kg.  Air module  Ground module4.
