Matrix High Performance 7.4V Brick Type Airsoft LiPo Battery (Configuration: 3300mAh / 20C / Small Tamiya)

"Got the 20C 2000 mAh 7.4v version. Fits fine in my TM P90 and works very well. Doesn't stress the wiring or contacts while working well for a stock spring gun.

"The one I actually got looks slightly different, but that's it. Got this, and some others, to test fit of a Krytac PDW stock...
Doesn't fit, but it still works (after 9 months) flawlessly for any other gun that needs 7.4v.

"Have one for my VFC Scar H ,2 years now still works good.

"This battery is a solid performer and will give you a faster rof than a 9.6v nimh battery it just barely fits in my JG Aug and is substantially smaller width wise as a 8.4v I recommend this battery

Pros and Cons:
Huge ROF increase from 8.4v nimh
Fast trigger response
Small

"Good battery, nice lifespan. Gives me very noticeable increase in trigger response over my 9.6v, but ROF stayed about the same. Works well, very reliable, and I don't foresee any problems in the future. Great battery for the money!

"Good Battery. I've had this thing toughly 2 months and haven't had any problems with it. Bought it because my battery space is tight with my Aeg Burst Wizard and it fits nicely. Just needing a higher rate of fire so I'm looking around for some 11.1v now. For a 7.4v though you can't complain at all.

"Bought this for my ICS SIG552 because it had such a tight fit. Works beautifully although it is still a tight fit. No problems with the evike provided charger, and my fire rate seems much better than with a standard 8.4v. Perfect for the ICS SIG552 in my opinion.
