I can't go in to details about what we are doing, but we do have a LOT of experience here with charging and handling batteries. Right now I'm just looking in to sourcing for these connectors. Do they have a standard distribution channel or are they a completely proprietary item?

Does anyone know where I could buy both the male and female connectors associated with the Phantom 4 battery?

What do these pins do? Are they some kind of way for DJI to check if your are using genuine parts? Are they there to pass on battery/cell info? Are they there to tell the battery if it's in a drone or on a charger? All of the above? Does anyone know anything about the communication protocol used?

I guess it could have been asked that way. Ultimately though, the behavior that we want would be for a person turn the battery the very first time the drone is deployed, and then have the battery always stay on, unless it goes completely dead, or a person turns it off. Basically, the battery...

Yes. That is what our system does, charge the battery by applying s DC voltage to the terminals....

With our application, that would not be an issue, as the charging system would (while yes drawing some small continuous power from the battery) continuously monitor the battery and automatically kick on if the battery ever dropped below a specified threshold.

Our experience with these batteries appears that this is more than just a "no-load" situation. It appears that the battery actually detects that it is being charged, and instantly switching in to a "charging mode". Unfortunately for us, this means that the battery will shut off as soon as...

Autonomy. We don't want to have to have a person to go turn the drone back on after it is done wirelessly charging. Especially if the drone is charging in a remote or hazardous location.

Does anyone know if it is possible to force a P4 battery to stay on, even after charging?
