The Traxxas Battery Expansion Kit (TRX10119) is an essential upgrade for owners of 2WD Rustler and Stampede RC models, particularly those running the #10122 chassis. This clever modification kit allows you to install taller battery packs into your RC car, opening up a world of possibilities for extended runtime and improved performance. Whether you're a casual basher enjoying your RC car UK weekend adventures or a serious enthusiast looking to maximise your on-track time, this battery expansion kit provides the hardware needed to safely accommodate larger capacity batteries without compromising the integrity of your vehicle's electronics or chassis.
In the competitive world of RC hobby in the UK, having the right upgrades can make the difference between a good day and a great day at the track or bash spot. The Traxxas Battery Expansion Kit removes a significant limitation from the standard 2WD Rustler and Stampede platforms, allowing you to experiment with battery configurations that weren't previously possible in these popular ready to run RC vehicles. This is particularly valuable if you've invested in higher-capacity LiPo batteries and want to unlock their full potential without worrying about fitment issues or having to modify your chassis dangerously.
Traxxas is renowned throughout the RC community as a manufacturer of reliable, performance-focused components, and this battery expansion kit is no exception. The kit is engineered with the same attention to detail and quality that you'd expect from one of the world's leading RC vehicle manufacturers, making it a trusted choice for RC enthusiasts across the UK and beyond.
Key Features
- Electronic Speed Control Mount Spacer Hardware — The kit includes precision-engineered hardware that raises the electronic speed control (ESC) mount, creating additional clearance for taller battery packs to fit comfortably within the chassis without interference with critical electronic components.
- Battery Post Elevation Kit — Alongside the ESC mounting hardware, the expansion kit provides spacers and mounting brackets that raise the battery posts themselves, ensuring that larger batteries sit at the correct height and remain securely fastened during aggressive driving.
- Designed for 2WD Rustler and Stampede Models — This kit is specifically engineered for Traxxas 2WD Rustler and Stampede vehicles, ensuring perfect fitment and compatibility with your existing chassis, mounting points and electrical systems without requiring dangerous modifications or compromises.
- Complete Hardware Package — Everything you need to perform the upgrade is included in the box, with all fasteners and spacers supplied to a high standard, reducing the need for additional purchases or improvisation.
- Maintains Structural Integrity — Rather than requiring you to cut, drill or permanently modify your chassis, this kit works within the existing Traxxas design philosophy, using official hardware to achieve the battery expansion safely and reversibly.
- Enables Larger LiPo Compatibility — By accommodating taller battery packs, the kit allows you to use higher-capacity LiPo batteries, potentially extending your run time and giving you more options when selecting power sources for different driving conditions or racing formats.
Technical Performance
The Traxxas Battery Expansion Kit represents a carefully considered engineering solution to a common limitation faced by 2WD Rustler and Stampede owners. The kit's hardware is manufactured to the same exacting standards as the vehicles themselves, utilising materials and fasteners that match the durability and reliability expected from Traxxas products. The mounting system works by strategically raising both the ESC and battery mounting points, creating vertical clearance within the chassis that accommodates taller battery pack dimensions. This approach maintains the vehicle's centre of gravity and weight distribution whilst eliminating the fitment constraints of the standard configuration. The kit is compatible with standard Traxxas 2S and 3S LiPo batteries in extended formats, as well as alternative battery chemistries that fit within the expanded envelope. Build quality is exceptional, with all spacers precision-manufactured to ensure flush, wobble-free mounting of your speed controller and battery pack. The engineering ensures that your electronics remain protected and properly positioned, maintaining cooling airflow around the ESC whilst securing your battery pack against the forces of aggressive driving, jumps and high-speed corners typical of 2WD stadium truck racing and bashing in the UK.
