Traxxas Power Cell Series 4 packs are optimized for free-flowing power and maximum punch with premium quality, low-resistance cells; flexible, silicone-jacketed 12-gauge wire; heavy-duty welded tabs; and Traxxas’ high-output, gold plated, high-current connectors. Precision assembly with attractive, individually wrapped cells and clear overwrap complete the package.

Traxxas hump pack, high voltage, high current. Traxxas high current connector with 12 gauge wire. Series 4 power cells.

Experience faster acceleration, faster top speeds, and Traxxas quality and support with the only batteries engineered for your Traxxas model.

The Series 4 cells deliver 40% more capacity than typical sport packs (3000mAh), and that means longer run times—but that’s just the start! Greater capacity also means the Series 4 packs maintain peak voltage levels under load, so that punchy, just-charged feel lasts longer than ever.

Traxxas Series 4 Power Cell battery packs provide the most power and runtime possible with NiMH cells. Upgrading from a 6-cell pack to the powerful Traxxas 7-cell 8.4V pack is the most cost-effective way to instantly increase top speed by 5mph or more with no other modifications. The 7-cell hump pack fits in all Traxxas models except E-Maxx® and E-Revo®, which require a stick pack configuration.

* 40% greater capacity than typical sport packs for more “punch,” and longer run times
* Heavy-duty construction to withstand high-current output
* Built with Traxxas High-Current Connectors for the most reliable and efficient power transfer
* 12-gauge wires with flexible silicone insulation resist damage and allow easy installation
* Premium-quality high-capacity, high-voltage, low-resistance cells deliver maximum run time and ‘punch’
* Optimized for maximum performance in Traxxas models

Traxxas Battery Basics

NiMH, NiCd, LiIon, LiFe, and LiPO
These terms refer to the materials and chemistry within the battery. Nickel batteries (NiMH, NiCd) have cells with the familiar “cylinder with a button on top” construction and a metallic case. Lithium batteries (LiPO, LiIon, LiFe) are usually constructed of flat cells stacked together. The cells may be encased in heat-shrink to form the final pack, or enclosed in a “hard case.” Traxxas Power Cell LiPOs use a “semi-rigid” design that is durable and allows greater battery capacity in a pack of a given size.

NiMH = Nickel-metal hydride
NiCd = Nickel Cadmium
LiIon = Lithium Ion
LiFe = Lithium Ferrous Oxide
LiPO = Lithium Polymer
