Swapping out batteries only increases the rate of fire like others said. Just as a note, decreasing FPS also increases rate of fire.
You have 2 options to decrease fps:
Replace the spring
You would probably want an m100, around 340fps. DO NOT CUT SPRING IT IS A CRAPPY WAY OF REDUCING FPS THAT WILL BREAK YOUR GUN.
TM velocity reducers
I'm not sure if would trust these though...
Which gun do you have? If you have a VFC, or ICS, you shouldn't pay somebody to install a new spring. VFC has it's quick change feature, and you can take ICS apart with 2 bolts (I think).
