Power module terminals?

Hi hi,

I bought power module and want to connect it to Pixhawk 2.4.8

I tied to follow the diagram in this link

I could see my power module has battery side (on the left) as female and esc side as male . my lipo has female connector as well.

I kept searching to find another figure with different labels to battery and esc.

Does it matter which side shall be connected to ESC and which one to battery??

It matters. Some of these power modules have a current flow arrow on the pcb.

Do you mean this one???

Maybe. Here is another one with no question.

Yours is a different from mine. Specially this large capacitor which is missing from mine
I bought mine from Aliexpress for $4.5
What about yours??

I don’t have that module just an image from one commonly available. All Lipo batteries have female XT connectors plug it in.
