Well, a couple of my buddies (but not me) are quite a bit into airsoft, and have Fully Automatic Electric Guns.
One shoots about 400FPS (feet per second) and the other shoots about 300FPS.
They both run on ~1500mah NiCd Packs. They are 7 cells, so 8.4v.
Well, we found out the guns can handle extra voltage, so we decided to hook up one of my FlightPower 3S 3700mah EVO25 packs. Anyway, results were RIDICULOUS.
Firing rate went from a "pop pop pop" to a constant hum. While the amount of BB's coming out of the gun appeared to be a solid stream. Me and my buddies were in tears laughing. It was so much firepower its almost not even funny.
(now they all want Lipo's for their guns)
Just thought I'd share...
