FIREFOX Premium Lithium Ion (Li-Ion) Battery:
- FIREFOX has been the golden standard (literally) for Airsoft batteries for over a decade;
- Battery fits most M4-style buffer tubes;
- Deans (Plug) connectors available for separate purchase or fitting to your battery;
- Plug: mini-Tamiya;
- Voltage: 7.4 V (2 cells);
- Capacity (actual): 1500 mAh;

Note: Many vendors advertise their batteries having a much higher capacity that they actually have. FIREFOX has maintained their reputation as an industry leader through providing accurate information about their quality products.
A real-world parallel to understand the capacity false advertisement many companies use is to understand that you cannot fit more than 500 ml on liquid in a 500 ml bottle. Same with batteries, especially cheap ones which do not use high density cells.
Warning: Lithium batteries pose serious fire hazard. Always charge and store your batteries in a fireproof LiPo bag. Always use dedicated chargers for Lithium batteries. Never charge above 1C rating (i.e. the mAh rating of the battery). Never leave charging batteries unsupervised. If your battery becomes damaged or swollen, discard immediately with an authorised used battery collector.
