Traxxas’ 3300mAh Power Cell LiPo packs are ideal for all Rustler, Stampede, Bandit, and Monster Jam models. Power Cell LiPo packs are engineered to give the punch and on-demand power to reach the top speeds Traxxas models are built to achieve. Premium LiPo cells developed specifically for Traxxas feature oversized discharge tabs for maximum efficiency. The cells are hard-wired with 12-gauge Maxx® Cable, eliminating the resistance and power-loss associated with plug-in wires. The standard XH plug permits balance charging with the #2933 EZ-Peak Plus LiPo/NiMH charger, and the Traxxas High-Current Connector assures total power transfer for higher speeds, longer run time, and more fun from every charge. The packs’ semi-rigid construction results in a firm, rugged, and compact pack that does not require a hard case, and the center-wire configuration assures a pinch-free fit in Traxxas vehicles.
