Does automatic fire drain the battery faster?
 

Obviously, it drains the battery faster because the AEG fires faster.

What I really want to know is if 100 BBs fired in full auto will drain the battery more than 100 BBs fired in semi-auto.

If yes, is it a significant difference?

100 BBs fired in semi auto will actually draw more battery power than 100 BBs fired in full auto.

Why?

The motor requires more start-up current to crank the spring from a standstill, whereas if it was already in motion.

I thought it was the opposite, but that makes sense. Thanks!
