Nuprol 7.4v 1200mAh 20C LiPo (Stick)

LiPo offers more power in a smaller package, however it is a little more volatile and requires greater care and attention - if you are looking for maximum performance, then Lipo is your battery...if you prefer lower maintenance, then stick with the NiMh. LiFe is a middleground between LiPo and NiMh; it is not as powerful as Lipo but as a result it is more stable.

These 7.4v Lipo batteries are some of the best drop in performance boosting batteries on the market! Not quite as aggressive as an 11.1v they will happily run in most guns. Manufactured by Nuprol, these batteries will last for longer (each usage), and last for more charge/discharge cycles than their competition e.g. Turnigy etc. The benefit of these batteries is that they are very thin, making them perfect for use in Airsoft stock tubes, even in conjunction with many MOSFET's. Although only 1200mAh, these batteries offer a lot of power, and last for quite a long while.
