The Valken 2-4 Cell LiPo/LiHV Quick Balancing Charger is a plug and play balancing smart charger for lithium airsoft battery packs. The LiPo charger comes with its own power supply cable, and charges LiPo battery packs at 2A through 3-pin, 4-pin, or 5-pin charging ports. This lithium airsoft charger will safely charge lithium polymer airsoft batteries incredibly fast. Balance ports support the 7.4v, 11.1v, and 14.8v, which smart balances each individual cell to ensure maximum life. The LiPo charger also features reverse polarity and short circuit protection built in, as well as over-charge and over-current protection. We recommend using our Valken LiPo Battery Safety Sack to safely charge all lithium batteries.
