DJI’s first battery-swapping dock gets drones recharged and back in the air in under 45 seconds

The dock bypasses the normal recharging process, which would take about 30 minutes, and DJI promises a turnaround of under 45 seconds from landing to takeoff. The drone-in-a-box solution is the first of its type by the company, although not in the industry, and is aimed at applications like emergency response but is not FCC-authorized or for sale in the U.S.

Its product page calls it “Always There, Always Ready.” Swapping the battery takes less than half a minute, and the drone is back in the air within 45 seconds of landing. The dock also charges two 925 g battery packs, rated at 260 Wh for 400 cycles, at once, estimated to take 27 minutes to get each from 15% to 95%. …
