My thread certainly got hijacked at one point! But all for the better understanding of the batteries!
My original intention was to be able to use these batteries for custom builds as for all their shortcomings, DJI batteries tend to be quick power dense and reliable. So to answer my original question:
@Mad_angler1 Is it possible to actually USE the battery by shorting the 2 end pins with a 3.3k resistor and drawing power out of the other pins? Can you provide a more detailed diagram of the pinouts, properly labelling data, control, cells, etc. The colour coding is good, but you haven't covered all the pins in your explanation.
@Dobmatt Same question to you - can you use that adapter to actually draw large amounts of power from the battery? If I integrated that connector into a 3rd party airframe and spliced the other end into my ESC/Motor power circuit will it actually run a system? It's a "charging" cable so I doubt it is meant to carry large amounts of power the other way.
