the older nimh/nicd batteries can't stand a pulse load. their voltage drops when they get this pulsated load. I don't know how lipo's handle this, but according to all the experiences others have shared about the added capacitors i expect them to do the same.

Since the batteries voltage drops, current needs to increase to get the same power, this is why caps are able to help out; they can handle a pulsating load, and the battery doesn't 'see' the ripple because of the capacitor.
