** Solution found read bellow **

I bought a official Remote Controller Charging Cable (Spare Part no.12)
But I can't get the TB50's to power up to supply power trough the cable (standard RC and Cendence).

If I rember it correctly there was a change in the TB50 power up behaviour a while ago.
I believe the  TB50 need some resistor or communication to power up.
But if this is the case, the offical sold cable is a joke and not working at all. I though it should work with this cable.

Official dji product text:
The Inspire 2 remote contoller can be charged by connecting it to an Inspire 2 Intelligent Flight Battery using this cable.
Compatibility
Inspire 2 - TB50 Intelligent Flight Battery (4280mAh)
Inspire 2 - Remote Controller



Or do I miss something?

My fault, found the problem.
The TB50 plug on the Remote Controller Charging Cable has a nose, which needs to be lined up with the inner side ob the TB50.
If placed correctly the TB50 will imediatly power up without even pressing any button.

BTW the most elegant way to close the thread is to edit the title by adding (SOLVED) ...
