||GREAT battery. And at 28 bucks, can't get any better.
Fits perfect in my Echo1 G36C. You just have to cut off the little tab that is supposed to hold 8.4v battery.
FYI. Batteries do NOT change FPS, they only change the ROF (rate of fire) The higher the voltage, the faster your gun will shoot. The higher the mAh, the longer your battery will hold a charge.
Most important, USE A SMART CHARGER. This is such a nice battery, you'd hate to ruin it by over-charging it.
High mAh for a small type battery
Increases ROF dramatically.
