Key Features

• 1800mAh Capacity — The 1800mAh capacity strikes an excellent balance between runtime and weight, providing extended running sessions without adding unnecessary bulk to your RC model. This capacity is proven to deliver competitive runtimes across a wide range of Traxxas vehicle types, from nimble 2WD buggies to heavier 4WD stadium trucks.
• 7.2V 6-Cell NiMH Chemistry — The 7.2-volt output from six NiMH cells provides stable power delivery throughout the discharge cycle, ensuring consistent acceleration and performance from start to finish. NiMH batteries are forgiving, reliable, and do not require the specialist charging equipment or storage precautions that lithium-based alternatives demand.
• Low-Resistance Cells — Traxxas engineers have selected low-resistance cell chemistry to minimise voltage sag under load, meaning your RC model maintains responsive throttle control and strong performance even during intense runs. This results in faster acceleration and more predictable handling characteristics that serious RC drivers will appreciate.
• Flexible Silicone-Jacketed 12-Gauge Wire — The wire connecting the cells is covered in flexible silicone insulation rated for the high currents that RC motors draw. The use of 12-gauge wire means lower resistance and better current flow compared to thinner alternatives, which translates directly to improved performance and less wasted energy as heat.
• Heavy-Duty Welded Tabs — Rather than soldered connections that can weaken over time, Traxxas has utilised heavy-duty welding to secure the internal connections. This manufacturing approach creates more reliable joints that resist vibration and thermal cycling, extending the battery's operational lifespan and maintaining safety during demanding RC sessions.
• Tamiya Connector — This battery features the industry-standard Tamiya connector, one of the most widely used connectors across RC car UK models and compatible with the vast majority of Traxxas vehicles. The Tamiya connector is robust, reliable, and provides excellent electrical contact with minimal resistance.
• Flat Stick Configuration — The flat, stick-like form factor is specifically designed to fit the standard battery compartments found in Traxxas RC vehicles, ensuring a perfect fit without modification or adapters. This practical design choice makes swapping batteries quick and hassle-free between runs.
• Affordable Entry Point — The Power Cell range represents outstanding value for money in the RC hobby, delivering genuine Traxxas engineering and reliability at a price that makes it easy to justify buying a second or third battery to rotate during extended play sessions.

Technical Performance

The Traxxas Power Cell NiMH 7.2V 1800mAh 6-Cell battery is engineered with meticulous attention to the demands of real-world RC use. At 7.2 volts, this battery delivers the correct voltage specification for Traxxas models designed around 6-cell NiMH packs, providing stable output that allows the vehicle's ESC (electronic speed controller) and motor to operate at their designed performance envelope. The 1800mAh capacity represents a proven sweet spot in RC car UK applications—large enough to deliver extended runtime for bash sessions and competitive driving, yet compact and lightweight enough to maintain the vehicle's balance and handling characteristics. With dimensions of 128mm length, 45mm width, and 24mm height, the battery occupies minimal space within the vehicle's chassis, and the flat profile ensures it sits securely without rattling or shifting during aggressive driving. The low-resistance cell chemistry is critical to performance: as your RC motor draws current during acceleration, voltage naturally sags slightly, but Traxxas's cell selection minimises this effect, ensuring the motor receives consistent power delivery throughout the battery's discharge cycle. This translates to predictable, responsive throttle control that competitive drivers rely on. The 12-gauge silicone-jacketed wire is substantially thicker than the 14 or 16-gauge wire found in budget alternatives, reducing resistive losses and allowing more of the battery's energy to reach the motor rather than being wasted as heat in the wiring itself. The heavy-duty welded tabs create robust internal connections that resist the thermal and mechanical stresses of repeated charge and discharge cycles, safeguarding against the internal resistance creep that can gradually degrade performance in batteries with soldered connections. For RC enthusiasts running Traxxas vehicles—whether brushed or brushless, 2WD or 4WD—this battery provides the reliability and performance characteristics needed for serious hobby use.
