Having some trouble understand whether the "BAT+" can be used to power the "V" on the FC.

The website for the T-Motor product states"


So can it be used to power FC? I guessing it does since it provides same voltage for sensing.

Hello, yes, presuming your Flight Controller can take battery voltage (which almost all do), then BAT+ is the pin for you. Their description is a little misleading, but what they mean is that typically your flight controller will also have a voltage divider on the battery input which sends a scaled signal to your FC that reports out/monitors the battery voltage (I'm not aware of any that call this a the "Battery Volt monitoring port").

I've wondered if that 26-30AWG wire can carry enough current for everything you could possibly drive off the FC power (which could be 2-3 amps if you have LEDs, VTK on high power, etc). I sometimes will wire separate power leads, but that may just be paranoia.
