In the end, DJI decided to share technical data about motors and cells in batteries. The cell type is of particular interest due to the unusual nominal voltage.
Model of Motor: 1504C
Type of Motor: Brushless
Diameter: 18 mm
KV: 2824 rpm/V
Rotation Speed While Hovering (Rated Operating Voltage): 6040 rpm
Maximum Rotation Speed (Rated Operating Voltage): 10700 rpm
Rated Output Power of One Single Motor: 3.71 W
Maximum Output Power of One Single Motor: 22.3 W
Rated Operating Voltage of One Single Motor: 7.4 V
Distance between the installation positions of two screws on a motor: Approx. 1 cm


Battery chemical type: LiNiMnCoO2 3,69V/4,25V

Interesting information.  Thanks for sharing.

Thanks for sharing. .  

It seems odd to me that they would state the screw distance is "approx ". I'd bet it is specified to 0.1mm or finer.
Where did you get these from?

Hello. Can you help me find similar information on motors for Autel nano. I want to put motors from DJ to autel. On fpv drones, I put different motors on one drone without any problems at all and the speed controllers pulled it all out, I hope autel will pull it out, but I want to be sure that they have the same characteristics and dimensions.
