Spektrum Smart Powerstage 4S Surface Bundle

Run higher-voltage surface vehicles with the Spektrum Smart Powerstage 4S Surface Bundle, a one-box solution that includes two Smart G2 5000mAh 2S LiPo batteries with IC5 connectors paired with the dual-channel S2100 Smart charger. The S2100 delivers up to 100W per channel across two independent outputs, letting both included batteries charge and balance simultaneously through a single IC3 or IC5 connection each, with no separate balance leads required. Beyond the two included packs, the S2100 also charges 1 to 6S LiPo, LiFe, Li-Ion, and LiHV batteries as well as 1 to 12S NiMH or NiCd packs, making it useful for a wider collection of batteries beyond this bundle. A color LCD screen with intuitive menus, icons, and navigation displays a clock countdown showing exactly how much charging time remains on each channel. Both included batteries are rated for a strong 50C continuous discharge for hard-accelerating builds, and an integrated memory microchip stores each battery's unique parameters for consistent performance over time. An Auto Storage feature automatically discharges each battery to a safe 3.90V after 72 hours of inactivity, helping protect battery health during storage between race days.
