Designed from the start for high-voltage, high-capacity LiPo packs, Traxxas’ VXL brushless models now include genuine Traxxas Power Cell LiPo batteries—the only LiPos
certified to deliver the full performance potential of Traxxas’ VXL brushless models. The Rustler, Bandit, and Stampede VXL each include a 3300mAh Power Cell pack; Slash VXL includes a 4200mAh battery. The Slash 4X4 VXL includes one 4200mAh LiPo battery and Stampede 4X4 VXL includes one 4000mAh LiPo battery.
Each LiPo-equipped model arrives with Low Voltage Detection activated to assure maximum battery life and prevent over-discharging. Charging care is just as important to LiPo life and performance, so a 2-Cell / 3-Cell LiPo Balance charger is also included. Just plug the battery’s balance plug into the charger and you’re on the way to another run—no programming or settings required. Every time the pack is charged, the cells are charged individually to precisely balance voltage for optimum performance, run time, and cycle life. Experience the ultimate in electric horsepower with the only models designed for LiPo power from the start, and genuine Power Cell LiPo technology on board.
