[0002] A coaxial twin-propeller drone is a type of drone that features two coaxial, counter-rotating propellers to provide lift and control. This design can give the drone better stability and control performance, while also improving its flight efficiency and load-bearing capacity. The two propellers of a coaxial twin-propeller drone can generate two thrusts in opposite directions, thereby offsetting the torque generated by the rotation, making it easier for the drone to remain stable. In addition, this design can also make the drone more flexible during flight, able to quickly change flight direction and altitude, and is very suitable for scenarios that require high maneuverability, such as aerial photography, reconnaissance, etc. Most of the batteries of existing coaxial twin-propeller drones are directly fixed to the bottom of the drone by bolts, which is very inconvenient to disassemble, or are installed on the bottom of the drone by snaps, and the connection is unstable.

[0019] A battery assembly 4 is connected to the bottom of the drone body 1. The battery assembly 4 includes a connecting cable 401, a limiting hole 402, a docking thread 403, a battery cell 404, a packaging shell 405 and a supporting leg 406. The packaging shell 405 is connected to the bottom of the drone body 1. The battery cell 404 is arranged in the packaging shell 405. The connecting cable 401 is connected to the battery cell 404. The inner wall of the packaging shell 405 is provided with a docking thread 403. A limiting hole 402 is provided at the upper edge of the packaging shell 405. A supporting leg 406 is fixedly installed at the lower end of the packaging shell 405. The packaging shell 405 can be connected to the bottom of the drone body 1 through the docking thread 403.
