Powering that Pew, Pew-Beast with the Airsoft battery.
Most airsoft replicas that you purchase don't include a battery or a charger and those that do, you are more often than not, better off not using them....
Sooooo.... now you need to purchase a new battery and charger, where do you start?
First, I would like to clear up the common myth about upgrading to larger voltage batteries: THEY WILL NOT INCREASE YOUR FPS. So don't think that if you're currently running a small 8.4V battery and you bump up to a 12V battery that you're going to see an increase in the velocity of your rifle.
Voltage
More voltage equals faster trigger response and a higher rate of fire (ROF) when using full-auto. Higher voltage is also needed in high-torque setups like DMR rifles in order to give the motor enough power to pull back the heavy spring.There is also a tradeoff though as with the higher voltage, electrically it can cause the trigger contacts and motor to burn out faster and as the overall rate of fire increases, it can lead to faster and more catastrophic failures in the gearbox.
A good example is found in the Masada that I just purchased. It was run with an 11.1 V Lipo battery - the very first time that the kid took the new toy out! The result? He stripped the teeth off not only the piston but off one of the gears as well, turning his gun into a $249.99
