Swiss Arms | 8.4V 1600MAH NIMH Battery

Airsoft electric guns require rechargeable batteries to operate, and as you would imagine they are available in various shapes, sizes, and degrees of quality. What battery your auto-electric gun (AEG) uses will be determined by available storage space, quality of internal components, and personal preference. Ideally you want the largest capacity battery that will fit, as the greater the capacity the longer the battery will last. Voltage is up to you - higher the voltage, the better the performance (rate of fire and trigger response) however it increases the stress on the internal components. Finally you have the battery type - NiCd, NiMh, LiPo, and LiFe. NiCd is antiquated technology, and there is no good reason to continue with their usage - NiMh came in to replace them, as they are more stable, reliable and offer the same performance without suffering from charge memory (i.e. battery does not have to be discharged before charging).

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.

Manufactured by Intellect for Swiss Arms, this battery is extremely high quality. It is important to note that you should only charge batteries such as these with a SMART charger (i.e. one that features automatic cut off), as otherwise you risk burning out the battery. Configured in the nunchuck format, this battery is typically for M4 crane stocks, although can be used in full-stock guns as well as front wired M4's making it perfect for those who need a spare battery for more than one gun
