Lithium Polymer (LiPo) batteries provide higher capacity and superior performance surpassing the more commonly available Nickel Cadium (NiCd) and Nickel Metal Hydride (NiMh) batteries. However, using the LiPo power source requires the highest quality of internal components. To handle the extra power of LiPo batteries, the KM4A1 is equipped with a reinforced metal gearbox utilizing KWA’s exclusive 8 and 9 mm ball bearing bushing combination and case hardened, precision metal gear sets. Heavy duty springs and high-torque motors are matched for optimum results. High-grade metal alloy are used for the production of the upper and lower receivers. The KWA KM4A1 is capable of firing more than 20 rounds per second and well over 400 feet per second when powered by an 11.1v Lithium Polymer battery.
The decision to develop LiPo-Ready products came after the successful introduction of KWA’s high performance AEG, the KG36C. Positive feedbacks and overwhelming demands from the industry accelerated the engineering of an AEG capable of utilizing the LiPo power source. The KWA KM4A1 will be released in the US in mid September 2007 and will only be available through KWA USA Authorized Resellers
