The Valken NiMh Power Kit comes with a Valken 9.6v 1600mAh split type NiMh airsoft battery and Valken 8.4v-12v NiMh Fast airsoft battery charger. The 9.6v 1600mAh Split Type NiMh airsoft battery is made from high performance 1.2v cells. This NiMh battery has a slimmer design making it easier to fit into cramped battery compartments. The NiMh nunchuck battery is also easy to charge, and does not require discharging like NiCd battery packs. This NiMh butterfly battery has a long recharge life cycle, and consistent, reliable power output. They are built with 16AWG wiring and include a mini Tamiya connector. The Valken 8.4v-12v NiMh Fast airsoft battery charger is a plug and play smart charger for NiMh or NiCd batteries with 7-10 cells. The NiMh battery charger is easy to use, and charges at 1 Amp with a small Tamiya connector. The NiMh charger also plugs directly into a wall outlet, and a status LED lets you know when the battery is fully charged with Delta Peak Detection. This airsoft charger also features over-charge and over-current protection. We recommend our Valken ASL Series airsoft rifles for use with this power kit.
