That's a linear BEC, so whatever current draw the servo draws comes directly from the battery.

A switching BEC is more of a "power transfer", so the higher the battery voltage is, the less current is drawn for a given servo draw. Ex: 5s battery and 1A servo @ 6v. 18.5v/((6v*1A) /80%) = 0.4A BEC current drawn from the battery. The 80% is a typical BEC efficiency figure.
