This has been discussed in the past.

In THEORY, higher mAh does not affect rate of fire.

However, in practice, that is not the case. Why? Because of different cell structures.

Higher capacity cells have lower internal resistance than smaller cells. Lowered R with same V means higher I supplied. Basic Ohm's law. A higher capacity gun won't PUSH the gearbox to go faster. The gearbox will just use the available power to it. A stock gun is designed around a specific battery pack. Tokyo Marui suggests 1300mAh sub-C packs for optimum gun life for it's stock guns. Experienced tuners in Asia would not recommend much beyond that and don't even recommend going to full 2400mAh packs until you at least break the 350fps barrier.

Case in point: Take a stock gun, put in an 8.4volt 600mAh nicad mini pack. Fire full auto. Note the rate of fire.
Now take an 8.4 volt 2400mAh nicad sub-C pack and fire in full auto. Notice the rather drastic increase in the rate of fire?

Also, notice how after prolonged use (especially in an upgraded gun), the mini battery increases in temperature faster and higher than the large pack? That's because the increased resistance has to let off that wasted energy somewhere. It comes out in the form of heat.

What you're all reading on paper is fine and dandy: Yes, higher mAh means your gun will last longer. But you need to take into consideration other physical aspects of the cells.


Will the increased ROF of a 2400mAh sub-C pack on your stock gun damage the internals? Yes and no.

If you do a lot of full auto fire, the sector gear will come spinning around constantly at high speed. The stock spring may not be able to keep up with the speed, and the sector gear's teeth will end up raking the piston teeth before it has come to rest. I've personally seen this happen to a user's gun and it resulted in a chewed up piston and sector gear. This happened after less than one season of light play.

However, if you do a lot of semi-auto fire, there should be very minimal damage to your internals.
