I have a d-boys m4 and it came with a 9.4 volt 1100 battery . my question is that can Get a better battery to work in my gun that will raise the shots per minute and possibly the fps mainly the shots per minute without messing up my gun. Thank You All Very Much (P.S.) my gun has a battery box and if possible could you give me a link
Higher voltage will increase the rate of fire, but I wouldn't recommend it because most stock gears cannot handle that much stress. In other words, yes but you would have to put some very good internal upgrades into the gun, or else you could destroy the gun. And the battery cannot influence FPS of the gun, only rate of fire.
