This isn't a generic battery adapted for RC use—it's purpose-built from the ground up for Traxxas vehicles, which means better fit, better performance, and better reliability than aftermarket alternatives. If you're serious about getting maximum performance from your ready to run RC or custom build, a genuine Traxxas LiPo battery is the foundation you need.

Key Features

• Traxxas Certified Engineering — This battery is engineered and tested by Traxxas specifically for their RC models, ensuring perfect compatibility, optimal performance characteristics and reliability that generic batteries cannot match. When you buy a Traxxas Certified battery, you're buying peace of mind and proven performance.
• 11.1V 3S LiPo Configuration — The three-cell lithium polymer design delivers 11.1 volts nominal voltage, making this battery perfectly suited for all Traxxas VXL-3S brushless systems, hybrid models and 3S-capable vehicles. This voltage is the sweet spot for high performance without overloading your speed controller or motor.
• 5000mAh Capacity — With 5000mAh of energy storage, this battery provides generous run time for extended bashing sessions, allowing you to enjoy longer periods of fun without frequent pit stops for charging. The capacity is substantial enough for serious driving without being so large that weight becomes a handling liability.
• 25C Continuous Discharge Rating — The 25C rating means this battery can safely deliver 125 amps of continuous current (5000mAh × 25C), providing the sustained power output required by brushless systems to maintain consistent acceleration, top speed and responsiveness throughout your run. This rating ensures the battery won't become a performance bottleneck.
• Traxxas iD Smart Connector — The integrated iD connector provides automatic battery identification and recognition by compatible chargers and vehicles. This intelligent system takes the guesswork out of battery management, ensuring correct charging protocols and protecting your investment through advanced safety features.
• Stick Format Design — The compact stick-format design (155mm × 40-49mm × 20-29mm) is engineered to fit snugly into Traxxas model battery compartments without rattling or shifting during aggressive driving. This precise form factor is crucial for optimal weight distribution and vehicle handling characteristics.
• Simple Installation — No adapters, no modifications, no compatibility questions—the iD connector plugs directly into compatible Traxxas models for hassle-free installation. This simplicity means less time fiddling with your RC car and more time actually driving it.
• Maximum Speed and Runtime — This power pack delivers the most speed and run time available in its class, giving you the performance punch to reach the velocities your Traxxas model is designed for whilst maintaining that speed consistently throughout your battery cycle.

Technical Performance

The Traxxas Power Cell LiPo TRX2872X represents the pinnacle of purpose-built RC battery design for UK-based and international Traxxas enthusiasts. At 5000mAh capacity with an 11.1V nominal output, this 3S battery provides the electrical foundation for sustained high-performance driving across Traxxas's comprehensive model range. The 25C discharge rating is particularly significant—this specification means the battery is engineered to deliver 125 amps of continuous current, sufficient to feed the power demands of modern brushless motors (such as the Velineon 540XL and similar specifications) without voltage sag that would compromise acceleration or top speed. The Traxxas iD connector is not merely a convenience feature; it's an intelligent system that communicates battery specifications to compatible chargers and electronic speed controllers, automatically configuring charging parameters and activating safety protocols specific to the battery's chemistry and capacity. The stick format (155mm long, 40-49mm wide, 20-29mm tall) is precision-engineered to integrate seamlessly into Traxxas model battery compartments, ensuring optimal weight distribution, reliable electrical contact and zero movement during high-g cornering or aggressive acceleration. The lithium polymer chemistry provides superior energy density compared to NiMH alternatives, meaning you get dramatically more power and run time from the same physical size and weight. Construction quality is exceptional—Traxxas batteries are not budget products, but rather investments in reliable, repeatable performance that will serve you through countless hours of bashing, racing or trail driving.

Frequently Asked Questions

• What Traxxas models does this battery work with? — This 3S LiPo battery is compatible with all Traxxas models equipped with VXL-3S brushless systems or 3S-capable electronics. Based on the source information, compatible vehicles include the Traxxas Ford Raptor R 4X4 Ultimate, Maxx Slash (various colours), Slash Ultimate and VXL variants, Slash Extreme HD, Sledge Belted, Spartan SR, TRX-4 series crawlers (Ford F-150, Chevrolet K5 Blazer, Ford Bronco, Nissan Pathfinder, TRX-4 Defender), and numerous other current-generation Traxxas brushless models. Always verify your specific model's battery compatibility before purchasing.
• Is this battery suitable for beginners? — Whilst the battery itself is easy to use thanks to the intelligent iD connector, lithium polymer batteries require responsible handling. This is not a beginner-friendly battery in the safety sense—you must use a LiPo-specific charger, charge in a fireproof container, never leave the battery unattended whilst charging, and follow all manufacturer safety guidelines. However, for experienced RC enthusiasts or those under adult supervision who understand LiPo safety protocols, this is an excellent choice that will serve you well for years.
• How long will this battery last per charge? — Run time depends on driving style, terrain, motor specifications and load, but the 5000mAh capacity and 25C rating provide substantial energy storage for extended driving sessions. Most drivers report 20-40 minutes of continuous driving depending on the specific Traxxas model and driving intensity. Heavy acceleration and high-speed running will reduce runtime compared to moderate pace driving.
• What charger do I need? — You must use a Traxxas Certified LiPo charger specifically designed for the iD battery system. Standard chargers or generic LiPo chargers without iD recognition will not properly charge this battery and may damage it. Traxxas manufactures several compatible chargers including the EZ-Peak Plus and EZ-Peak Live, both of which include iD recognition and safety monitoring.
• How should I store this battery? — Store the battery in a cool, dry location away from direct sunlight, ideally in a LiPo-specific storage pouch or fireproof container. Never store the battery fully charged for extended periods—Traxxas recommends storing LiPo batteries at approximately 50% charge if you don't plan to use them for several weeks. This practice extends battery lifespan and enhances safety.
• What makes this better than aftermarket LiPo batteries? — Traxxas Certified batteries are engineered specifically for Traxxas models, with precise dimensions, connector specifications and electrical characteristics optimised for perfect integration. The iD system provides automatic battery identification and intelligent charging. Most importantly, when problems arise, you have direct support from the manufacturer. Generic aftermarket batteries may be cheaper initially but often lack the precision fit and integrated safety features, making them a false economy.
• Is this a genuine Traxxas product? — When purchasing from RC Model Shop, you receive genuine Traxxas Certified batteries with full manufacturer support and warranty coverage. Always purchase from authorised Traxxas retailers to ensure authenticity and access to warranty protection if issues arise.
