Keep your Mavic 3 flying. Non-stop.
The G12-M3 kit replaces the flight battery with a 370 g airborne module and feeds regulated 850 V DC from the ground — 24 h+ on station with the original battery held at ≥90% as an untouched reserve. Contact-free HV switching and automatic cable reel-in/out mean you never touch high voltage or approach the drone during take-off and landing; if ground power is cut the drone flies and lands normally while the cable auto-retracts, and cable break, disconnect or short-circuit trigger instant HV cutoff.
How the G12-M3 kit keeps power flowing
Ground power
Mains or generator — 190–240 VAC single-phase in.
Ground station
1.2 kW converter, motorized winch, comms, cooling and control in one case.
High-voltage tether
600–850 VDC over 33 m or 55 m of lightweight cable, auto-retracting.
Airborne module
370 g unit in the battery bay steps voltage down to a regulated 17.2 V output.
Mavic 3 + payloads
Camera, searchlight, speaker or drop system — fed continuously.
Ground station — G12-M3
A 3 kg hand-carry case holds the whole ground end: the AC/DC converter turns single-phase mains into 600–850 VDC (1,200 W rated), the servo-driven winch pays out and retrieves cable at 0–3 m/s with 0–10 N tension that follows the aircraft automatically, and the panel keys, mobile app, PC client and DJI remote controller all expose live voltage, current, cable length and fault logs. Over/under-voltage, over-current, over-temp and short-circuit protection with auto-recovery are built in, along with power-loss, over-unspool and cable-break safeguards.
Airborne module — 370 g battery-bay swap
The 370 g module slides into the Mavic 3 battery bay and locks tool-free — no brackets, no rewiring. It accepts the wide 600–850 VDC tether input and delivers a regulated 17.2 V, 600 W output to the aircraft and payload ports, keeping the onboard pack above 90% throughout the flight as an untouched reserve. The housing is rated IP54 and reports module status to the ground station over the same cable.
