Ok, thank you! I was getting around 6 bbs a second with the 7.4v one and I felt that that was plenty. I bought the 11.1v a little while ago since the old battery I have is pretty puffy. I didn't notice that it said 11.1v when I got it and hadn't compared the two until now. I'll have to get a new battery then since I can't afford to replace a bunch of parts so thank you for the information!
