Is Pixhawk 2.x version boards have embedded power module?How to close it or how to close preflight checks?

#1

I ve got a px4 2.4.8 fc . I am using it with qground controller. I installed px4fmu-v3 firmware in it.

When i want to arm it not arms. Qgroundcontroller says “PREFLIGHT FAIL: Avionics power low: 3.45 volt”.

I’ve not mounted a external power module,
I don’t want to use power module but i can’t close power checks in qgroundcontroller or preflight checks.

I need to close preflight checks or battery checks.

Need your helps.
