Traxxas’ 7600mAh Power Cell iD LiPo packs are ideal for all Slash, Slash VXL, Slash 4x4 VXL, E-Maxx Brushless, E-Revo Brushless, and Spartan 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 over sized 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. Integrated balance connectors make it simple to charge with the EZ-Peak Plus LiPo/NiMH charger with iD, 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. Covered under Traxxas' Lifetime Battery Exchange Program.
