Just like a high-performance race car, your airsoft AEG deserves to be paired with a premium power source. The Elite Force 7.4V Lithium Polymer (Lipo) 1500 mah stick battery is the solution to your small battery space needs. Due to design and aesthetic limitations often imposed by the original firearm, many airsoft replicas suffer from limited battery space. Thatâ€™s where the Elite Force 7.4V Lipo stick battery comes in. Small in size, but packed with power, this battery has the juice you need to cycle those rounds down range without taking up much real estate inside your airsoft AEG. We always recommend having a back-up battery pack on hand so that the fun stops when YOU decide, not your battery.
