Product overview
The CZI TH4 V2 is an aircraft-mounted supply-release accessory with four release stages, allowing four deliveries during one takeoff. Its compact body measures 76 × 98mm and integrates through DJI SkyPort V2.0 for quick installation and attachment of supplies. Control uses the DJI Pilot app without a third-party controller, with automatic load recognition and real-time information prompts. Electrical integration requires DC 12–36V, with rated power of 10W. The specified operating temperature is -20 to +50°C.
Payload planning depends on the aircraft and mounting arrangement. Each hook is rated for up to 2.3kg, subject to aircraft and gimbal capacity. With a single gimbal mount, total release payload is limited to 620g on M300 RTK or 650g on M350 RTK. Binding the upper and lower gimbal frames together with cable ties raises those limits to 2270g and 2300g respectively. The technical weight is 310±5g; introductory figures separately state 320g and a maximum single-release payload of 2.38kg. These differing figures make the configuration-specific limits central to integration planning.
