The DJI M300 drone tethered system can converts single-phase or three-phase AC power into DC high voltage, and transmits it to the onboard power supply through a high-performance nickel alloy power supply cable to continuously supply power to the drone. Combined with the use of backup batteries, it can achieve a max of 24 hours of continuous operation on the basis of ensuring a safe flight.
