Overview
The Traxxas Hold Down Battery Tray Kit TRX5827 is an essential upgrade for owners of the Traxxas Slash HD XL-5 1/10 2WD RC Short Course Truck who want to install taller multi-cell battery packs into their vehicles. This specialised chassis tune-up component is designed specifically to accommodate larger battery configurations, allowing you to increase your vehicle's performance potential without compromising on reliability or fitment. Whether you're a weekend basher looking to extend your run times, a competitive racer seeking an edge, or an enthusiast exploring new battery options on your ready to run RC car, this battery tray kit provides the solution you need.
Available for the Traxxas Slash HD XL-5 in multiple colour options including green, red, blue and orange variants, the TRX5827 is manufactured by Traxxas and represents genuine OEM engineering designed for perfect compatibility with your RC short course truck. This is not an aftermarket compromise but a factory-approved solution that maintains the integrity and performance of your Slash platform whilst expanding its capabilities. RC car enthusiasts across the UK have come to rely on Traxxas components for their durability, precision fit and performance benefits, and this battery tray kit continues that tradition of quality.
The kit comprises multiple components working together as an integrated system: a hold down battery bracket, hold down retainer, battery post, foam spacer and angled body clip. Each element serves a specific purpose in securing and positioning your battery safely within the chassis whilst accommodating the increased height of multi-cell battery packs. This comprehensive approach to battery mounting ensures that taller batteries remain stable during aggressive driving, jumping and high-speed running, protecting both your valuable battery investment and your RC truck's internal components.
Key Features
- Accommodates Taller Multi-Cell Batteries — This kit is purpose-designed to allow installation of larger capacity battery packs that would otherwise not fit within your stock Slash HD XL-5 chassis, giving you the flexibility to choose from a wider range of performance and endurance-focused battery configurations that suit your driving style and terrain.
- Complete Hold Down System — The kit includes a comprehensive battery securing solution with dedicated hold down retainer and bracket components that work together to keep your battery firmly in place, preventing movement or shifting during aggressive cornering, jumps and high-impact running that would otherwise damage both the battery and chassis components.
- Integrated Foam Spacer — A precision-engineered foam spacer is included to provide proper cushioning and spacing between your battery pack and the chassis, protecting your battery terminals and cells from impact damage whilst maintaining optimal electrical contact and thermal management during extended run sessions.
- Angled Body Clip Included — The specially designed angled body clip ensures secure fastening of the body shell to the upgraded battery tray, maintaining aerodynamic integrity and preventing the body from shifting or lifting during high-speed driving or when launching off jumps.
- Factory Traxxas Engineering — This is a genuine Traxxas component manufactured to the same exacting standards as the rest of the Slash HD XL-5 platform, ensuring precise fitment, reliable performance and long-term durability without any compatibility issues or modifications required.
- Chassis Tune-Up Category — Classified as a chassis modification, this kit directly improves the foundation of your RC short course truck's handling and capability, making it an investment in the core performance characteristics of your vehicle rather than cosmetic enhancement.
Technical Performance
The Traxxas Hold Down Battery Tray Kit TRX5827 represents careful mechanical engineering focused on solving a real problem faced by Slash HD XL-5 owners: the limitation of the stock battery tray to accommodate only standard-sized battery packs. By introducing a raised battery post and extended hold down retainer system, this kit increases the vertical space available within the chassis bay, allowing multi-cell batteries with greater capacity and physical dimensions to be safely installed. The foam spacer component is critical to performance, as it absorbs vibration and impact energy that would otherwise transmit directly to your battery cells, reducing stress on internal circuitry and extending battery lifespan. The angled body clip has been engineered to provide consistent pressure across the body mounting points, preventing the body shell from lifting during acceleration or becoming loose during impact events. Construction quality is exemplary throughout, with materials selected for durability and precision tolerancing that ensures fitment to your specific Slash HD XL-5 variant, whether you own the green, red, blue or orange edition. This is the kind of thoughtful engineering that separates Traxxas from lesser manufacturers — every component serves a purpose and contributes to the overall robustness of your RC car.

Frequently Asked Questions
- Will this battery tray kit fit my Traxxas Slash HD XL-5? — Yes, the TRX5827 is specifically designed and engineered for compatibility with all Traxxas Slash HD XL-5 1/10 2WD RTR Short Course Truck variants, including the green, red, blue and orange models. This is a factory Traxxas component with guaranteed fitment to your chassis.
- What size batteries can I now install with this upgrade? — The kit is specifically designed to accommodate taller multi-cell battery packs that would not fit within the stock chassis battery tray. The exact dimensions depend on your specific battery pack, but the extended height of the battery post allows for significantly larger capacity options than the standard configuration allows.
- Is installation difficult or do I need specialist tools? — As a Traxxas OEM component designed for the Slash platform, installation is straightforward and requires only standard RC toolkit items. Detailed instructions are provided, and the kit's components are designed to integrate seamlessly with your existing chassis without modification.
- Will using a taller battery affect my Slash's handling or weight distribution? — The kit has been engineered to maintain proper weight distribution even with taller batteries installed. The positioning of the battery post and hold down system keeps the battery centred within the chassis, preserving the balanced handling characteristics your Slash is renowned for. The foam spacer also helps absorb vibration that could otherwise affect steering response.
- Can I use this kit if I run my Slash at the track? — Absolutely. Many competitive Slash drivers use upgraded battery trays to access larger capacity packs that provide the runtime needed for competitive racing whilst maintaining the weight and balance characteristics required for winning performance. Check your specific racing class regulations to confirm battery specifications are permitted.
- Is this suitable for beginners? — Yes, this is an excellent upgrade for newer Slash owners who want to improve their vehicle without requiring advanced mechanical knowledge. The kit's straightforward design and integration with the stock chassis make it accessible to all experience levels, whilst delivering genuine performance benefits.
- What is the difference between this battery tray kit and the stock setup? — The primary difference is the extended height accommodation provided by the upgraded battery post and retainer system. The stock chassis is designed for standard-sized battery packs, whereas this kit allows you to install taller multi-cell batteries, giving you access to higher capacity options for extended runtime or different battery configurations that your Slash could not otherwise accommodate.
