Hello,
I am currently in a small project where I am building a drone demo. I have made some software for the drone to run in a simulation. For this simulation I have used a HolyBro X500 V2. The drone will run the software and the motors will run to show the communication of the software to the autopilot. The problem is I want to make a automated demo. So when the lights of the room go on the drone will also start it's software. I don't want the drone to be connected to a battery, because there is a chance I forget to change the demo. The drone uses a 11.1V 50C battery. What can i do to substitute this for a power cable?

 

Will the drone be actually flying in the room, tethered by the power cable?
To recommend a power source, we need to know what is the maximum current the drone will need. My guess is around 25 Amps with the battery on-board.

 

No, the drone will not be flying. Only the rotars will be turning. It will be powering the autopilot and raspberry pi 5 through this way.

 

It will be much more impressive if the drone flies up even just three feet! And you can have a non-latched plug so if it gets away it unplugs itself. A handy cheap safety feature.

 

Why don't you just use the battery that it flies with as an external power source?

 

Because if i would use a battery then I would have to charge the battery when it is empty. I want to make a demo where I dont have to recharge it. The demo will be on display for the rest of the year and most of the time without my supervision. The demo will be using a smart plug, so I can turn the demo off when the company closes for the night. The drone will not be flying but the motors will turn to show that the communication between the autopilot and the simulation works.

 

As a substitute for that 11.1 volt battery, you can use a nine volt DC supply. That should power the logic portion quite well, and still spin the motors fast enough to show what is working.
