In my A5 front end on one of my MP5s, I bought an Intellect 8.4V 1400mAh mini for it, and it's a great battery. I don't know how long it'll last for number of shots, have a 110 spring in the gun, so if I'm lucky 1000 shots, but the gun is ripping fast, much faster than my main MP5 field gun (has the SD front end) with a 150% spring in it and an 8.4V 3300mAh battery. There is more room in the SD front end than the A5 style, but I never tried to fit a larger battery in.
