“ESCs without BEC are often referred to as OPTO (optoisolator). All this means that that the part of the ESC that receivers the signal from your flight controller or R/C receiver is isolated from the higher voltage circuit that powers your motors. OPTO ESC's are common on many multirotor setups as your dont always need a BEC as discussed above.”
