Overview
The Traxxas Battery Box, bumper (Rear) is an essential replacement or upgrade component for your RC car setup, designed to keep your battery secure, protected and organised during high-performance driving sessions. Whether you're a dedicated weekend basher enjoying RC off-roading across the UK or a competitive racer looking for reliable chassis protection, this rear bumper battery box delivers professional-grade build quality and practical engineering that Traxxas is renowned for. This isn't just a simple plastic cover — it's a fully integrated battery management system that combines secure storage, structural protection and convenient accessibility in one well-designed package.
For RC enthusiasts running high-powered electric RC buggies, truggies and monster trucks, battery security is critical during aggressive driving conditions. The Traxxas rear bumper battery box addresses this by providing a dedicated enclosure that integrates seamlessly with your vehicle's rear bumper assembly. This means your LiPo or battery pack stays firmly in place even during hard landings, jumps and high-speed cornering — situations where a loose battery could shift and damage your RC car's balance and handling. The inclusive design philosophy means everything you need is in the box: the battery case itself, the protective cover and precision-cut foam padding to cushion and secure your battery.
If you're investing in a quality RC car UK setup, protecting your power source is just as important as the motor and ESC. This battery box ensures your battery investment is safeguarded while maintaining easy access for charging and maintenance routines.
Key Features
- Complete Battery Enclosure System — The battery case features specially engineered bosses for wheelie bar mounting, meaning you can set up wheelie bar functionality without compromising battery security or space. This is particularly valuable for RC drivers who want to add stability features without completely redesigning their battery mounting arrangement.
- Integrated Protective Cover — The included cover shields your battery from dirt, moisture, debris and impact damage during outdoor RC car sessions. This protective layer is essential for extending battery lifespan and maintaining clean electrical connections that ensure reliable power delivery to your motor and ESC.
- Custom Foam Padding — Rather than loose mounting, the supplied foam pad secures your battery in position whilst absorbing vibration and shock from uneven terrain and aggressive landings. Proper battery padding prevents internal damage to LiPo cells and reduces movement that could affect your RC car's weight distribution and handling characteristics.
- Rear Bumper Integration — Designed specifically as a rear bumper-mounted assembly, this battery box positions your power source at the back of the chassis where it naturally balances weight distribution and improves handling dynamics. The bumper integration also means less internal space is consumed, leaving room for other performance upgrades.
- Professional Traxxas Engineering — Manufactured by Traxxas, an authorised and recognised leader in RC vehicle components, this battery box meets the exacting standards expected by serious RC enthusiasts and competitors throughout the UK.
Technical Performance
The Traxxas Battery Box, bumper (Rear) is constructed with durable materials engineered to withstand the demanding environment of RC off-roading and high-speed driving. The battery case itself provides rigid protection against crushing impacts and pressure changes that occur during aggressive driving. The included foam padding is precision-cut to accommodate standard RC LiPo battery dimensions, ensuring secure fitment without gaps or movement. The protective cover clips securely over the case, creating a sealed enclosure that prevents dirt ingress whilst remaining easy to open for routine battery maintenance and charging. The bosses for wheelie bar mounting are reinforced to handle the lateral forces generated by wheelie bar contact with terrain. This integrated system eliminates the need for makeshift battery mounting solutions or aftermarket straps that can loosen or fail during competition or casual play. Whether you're running a 2S, 3S or larger capacity LiPo battery in your RC car, this battery box provides universal compatibility through its spacious and adjustable padding design. The rear bumper mounting position means battery weight is distributed exactly where it should be for optimal handling balance in your RC vehicle.

Frequently Asked Questions
- Is the Traxxas rear bumper battery box compatible with all RC cars? — This battery box is specifically designed as a rear bumper-mounted assembly, so compatibility depends on your RC vehicle model. It's compatible with Traxxas vehicles that feature rear bumper battery mounting options. Check your vehicle's manual or contact our expert team to confirm compatibility with your specific RC car model.
- Will this battery box fit different battery sizes? — The battery case is designed with adjustable foam padding that can accommodate standard RC LiPo batteries in typical capacities. The padding can be trimmed slightly to fit batteries of varying dimensions, providing flexibility for different battery configurations. The main limiting factor is the physical case dimensions, but most competitive and bashable RC vehicle batteries will fit comfortably.
- What type of battery does this battery box hold? — This battery box is universal for most RC battery types, including LiPo, LiFe and NiMH batteries in standard RC car formats. The foam padding protects any battery chemistry, and the case is designed to accommodate the rectangular shape of most RC packs. Verify your specific battery dimensions against the case interior to ensure a snug fit.
- Why should I choose a dedicated battery box instead of just strapping the battery down? — A dedicated battery enclosure like this one provides superior protection compared to simple straps or velcro fasteners. The protective cover prevents moisture and dirt contact, the foam padding absorbs shock and vibration, and the secure case design prevents battery movement during aggressive driving. This reduces risk of battery damage, extends battery lifespan, maintains consistent handling by keeping weight centred, and looks more professional than improvised mounting solutions. For RC drivers serious about protecting their investment, a proper battery box is essential.
- Can I still access my battery easily for charging? — Yes. The cover is designed to open easily for routine maintenance, charging and battery inspection. You don't need to remove the entire assembly — simply open the cover, lift out the battery, charge it, and reinstall. This convenient access design means you won't waste time dismantling your RC setup between driving sessions.
- What is the wheelie bar boss feature for? — The integrated bosses for wheelie bar mounting allow you to attach an optional wheelie bar to your RC car without requiring a separate battery mounting system. This is particularly useful for drivers who want to experiment with wheelie bar setups for stability or style. The reinforced bosses are engineered to handle the forces involved when a wheelie bar contacts the ground during driving.
