Hi, I recently purchased the Pixhawk 4 and I am unsure how exactly the wiring works. The explain in the user guide gives just a single picture:

The part with how the 5V BEC connects to the LiPo battery confuses me... I don't understand how the two should connect. I have the battery, the BEC, and the PMB below:

So it seems I need to solder the 5V BEC to the two pins displayed, but how does the battery power both the BEC and the PMB? Do I need to split the signal coming out of the battery so that it can somehow go to both at once?
