Powering spirit WiFi module

[azaz44]

Quick question -
I have Spirit unit powered by BEC.
Can I connect Spirit Wifi-Link to it, but have the Wi-Fi Link powered from external 2S lipo?

I have the same question.

Yes, but only if ground wire is shared between battery and BEC.
This mean you might need Y cable for powering lead where side that goes to the Spirit unit should be without red wire.

[nichtdiemama]

Isn’t there an gnd connection in the wire between the spirit and the wifi module?

[ZeXx86]

Yes, it is if you connect powering wire from the Wifi-Link to the Spirit unit.

I wonder if we could take the ground from the black lead of the battery, which is easy to access over balancing port. I think it's probably equal to BEC ground, but I better test this before.

I think I'm talking rubbish
It seems it's just a matter of providing 2s Lipo ground to Spirit SYS port and things should work.

Yes, Ground can be connected anywhere with the BEC.

One point should be minded - not all ESC's like additional powersupply as Buffer-Packs or batteries -

Yes, but we only want to connect ground. Powerline of 2s will not be shared with BEC.
