This is for the blue/black XERUN 150A.
Does anyone know where on the internal board the full input voltage can be taken after the switch?
I feel it would be nontrivial to figure out since the tiny switch is presumably driving some kind of logic gate / solid state switching, not actually switching the full current. I'm hoping someone may have done it already.

Basically I would like the existing switch to also turn off the external BEC, rather than the BEC always staying on (or needing its own switch) when connected directly to the battery.

Thanks!
