UPGRADING : understanding (Li poly) Batteries

Well here's how (AEG) batteries work anyway. If a battery's voltage increases, so does the rounds per minute in an AEG motor, thus an increase in your rate of fire (ROF). All standard AEG batteries are 8.4 volts and the only difference between the different sizes is that a large battery has a minimum capacity of 1300 mAh, while the other small standard batteries have a capacity of 600 to 1100mAh.

mAh stands for Milliamp Hour, a technical term for how much power a particular battery will hold. This means that a battery with 1200 mAh will last for about twice the amount of shots than a 600mAh batt.
So in basic terms, your voltage is your power, and mAh is your battery capacity.

Upgrades inside a gearbox often reduce the rate of fire (due to the increased spring resistance) but if you then use a battery with a higher voltage like 9.6 V or 10.8 V, the rate of fire wont drop as much or even increase! But take note, according to AEG experts like mang domeng, a higher voltage also wears a motor down faster and more maintenance is required. According to sir Tupa, the maximum voltage an AEG motor can ideally take is 12 Volts, so it is possible to use 12 V to power an AEG but this isn't to recommend since the wear is increased very much; the contacts in the trigger is faster worn out and the overall lifespan of the internals is sharply reduced.

In addition : aside from modified stock batteries, some players from CAMP 7 use 12volts scooter/ motorcycle batteries enclosed in 6" by 4" aluminum casings to power their AEGS. aside from being self maintaining, this kind of set-up is way cheaper than buying Firefox batteries. This is also an economical but more technically advanced way to upgrade your power source.

take note : Li poly (lithium-ion polymer) batteries are considered the newest technology in terms of rechargeable batteries. This type of battery is considered to be the High-end and the ideal power source for AEG's. According to my references, Lipoly batteries are now being much preferred by all electronics companies because they are more economical / low-cost to produce. It is ironic thought that most manufacturing companies sell these kinds of batteries for a higher price.
