Key Features

• 5000mAh High-Capacity Design — This substantial capacity provides extended runtime on a single charge, allowing you to spend more time driving and less time waiting by the charger, which is particularly important for competitive racing or extended bashing sessions where consistent power availability determines success.
• 8.4V Nominal Voltage (7-Cell NiMH) — The 8.4-volt output provides optimal power for a wide range of Traxxas models, delivering the voltage sweet spot for both brushed and brushless systems that require stable electrical input throughout the discharge cycle.
• Premium Low-Resistance Cells — The use of low-resistance cells minimises internal voltage drop, ensuring that peak power reaches your motor and ESC without degradation, translating to faster acceleration, higher top speed consistency, and better overall performance compared to lower-quality batteries.
• Flexible Silicone-Jacketed 12-Gauge Wire — The silicone jacket provides exceptional durability and flexibility, allowing easy installation in tight battery compartments whilst the 12-gauge wire thickness ensures minimal resistance and reliable current delivery even during sustained high-current draw situations.
• Heavy-Duty Welded Tabs — Unlike soldered connections that can fail under thermal stress or vibration, the heavy-duty welded tabs provide permanent, reliable electrical connections that will not deteriorate over time or fail during the most demanding driving conditions.
• Traxxas iD® Battery System — This exclusive intelligent battery management system automatically recognises your battery pack, providing automatic safety features, charging protocol recognition, and compatibility assurance that ensures seamless integration with all compatible Traxxas chargers and vehicles without confusion or setup errors.
• Hump Configuration — The raised centre profile design fits the battery compartments of numerous Traxxas vehicle platforms, providing compatibility across multiple models and allowing you to build a versatile battery collection that works across your entire fleet of RC cars and trucks.

Technical Performance

The Traxxas NiMH 8.4V 5000mAh 7-Cell Power Cell Battery delivers exceptional technical performance through its carefully engineered cell chemistry and construction. With dimensions of approximately 139mm length, 48mm width, and 42mm height, this battery pack is optimally sized to fit standard Traxxas battery compartments without excessive weight distribution issues. The 5000mAh capacity provides substantial energy storage, which translates to extended runtime for RC enthusiasts who demand longer play sessions without frequent charging interruptions. The 8.4-volt nominal output is derived from seven individual NiMH cells connected in series, providing the precise voltage level required by modern Traxxas models featuring brushless ESCs and high-performance motors. The low-resistance cell chemistry ensures minimal voltage sag under peak current loads, meaning your vehicle maintains responsive acceleration and consistent top speed even as the battery discharges, unlike budget alternatives that suffer significant voltage depression when power-hungry brushless systems draw peak current. The silicone-jacketed wire and heavy-duty welded connections ensure that the high-current power path remains robust throughout hundreds of charge cycles, with no degradation in electrical reliability. When installed in compatible Traxxas vehicles, this battery pack integrates seamlessly with the iD charging ecosystem, enabling automatic charge profile selection and enhanced battery safety features that protect your investment and ensure optimal lifespan through intelligent charge termination and temperature monitoring.

Frequently Asked Questions

• What is the 5000mAh capacity and how long will this battery last? — The 5000mAh capacity indicates the total charge capacity of the battery pack. Runtime depends on your driving style, vehicle weight, motor power, and terrain. Aggressive high-throttle bashing will consume the battery faster than casual recreational driving. Typically, you can expect 15-30 minutes of driving per charge depending on usage intensity, making it essential to have multiple batteries for extended play sessions.
• Is this NiMH battery compatible with my Traxxas RC model? — This 8.4V NiMH battery is compatible with any Traxxas vehicle designed for 8.4-volt 7-cell NiMH packs. The hump configuration and Traxxas iD connector system ensures automatic compatibility verification when you plug it into any Traxxas iD-equipped charger. Always verify your vehicle's specification sheet to confirm 8.4V compatibility before purchase.
• How does the Traxxas iD® battery system improve the experience? — The iD system automatically recognises your battery pack and configures the charger with the correct charge profile, eliminating manual setup errors. It also provides enhanced safety features, temperature monitoring during charging, and automatic charge termination to protect battery longevity and ensure consistent performance throughout the pack's lifespan.
• What is the difference between NiMH and LiPo batteries for RC cars? — NiMH batteries like this Power Cell pack offer more durable construction, greater tolerance for physical damage, and more forgiving charging requirements with lower fire risk compared to LiPo alternatives. However, LiPo batteries offer higher energy density, lighter weight, and higher voltage output. For most RC car UK users, especially those new to the hobby or seeking rugged reliability, NiMH remains the preferred choice for recreational driving and bashing.
• Is this suitable for beginners and experienced RC enthusiasts? — Absolutely. The Traxxas NiMH battery is suitable for both beginners and experienced RC competitors. The iD system makes it beginner-friendly by eliminating charging confusion, whilst the premium low-resistance cells and high capacity appeal to experienced drivers who demand maximum performance and reliability from their power systems.
• What charger do I need for this battery? — You need a Traxxas iD-compatible charger to use this battery pack. The iD connector automatically communicates with iD chargers to select the correct charge profile. The Traxxas EZ-Peak charger family and other Traxxas iD chargers will all work seamlessly with this battery, providing convenient automatic charge protocol selection and safety monitoring.
