Key Features
- 50C Continuous Discharge Rate — This specification means the battery can safely deliver up to 270 amps of continuous current, making it ideal for high-performance racing applications where sustained power delivery is critical. The 50C rating ensures your brushless motor and ESC receive the stable, consistent power needed for competitive performance without voltage sag during demanding runs.
- 5400mAh Capacity — The 5400mAh capacity provides extended runtime for your RC car or racing vehicle, allowing longer driving sessions before requiring a recharge. This substantial capacity ensures you get maximum enjoyment from each charge cycle without the frustration of brief running times.
- 4S LiPo Configuration (14.8V) — The four-cell LiPo configuration delivers 14.8V nominal voltage, providing the power envelope required by modern brushless RC vehicles whilst maintaining compatibility with standard 4S-capable ESCs and receivers found in most contemporary racing setups.
- Hard Case Protection — The protective hard case safeguards your battery during transport and storage, preventing physical damage, punctures, and short circuits that could compromise battery integrity or create safety hazards. Hard case batteries offer superior durability compared to soft pack alternatives.
- XT90 Connector — The XT90 connector is a robust, high-current connector standard in professional RC racing, ensuring secure connections and minimising contact resistance that could cause voltage drops or heat generation during high-performance use.
- Up to 3C Charge Rate** — Supporting charge rates up to 3C means you can charge this 5400mAh battery at up to 16.2 amps, significantly reducing downtime between races. Fast charging capability keeps you in the action rather than waiting for batteries to charge.

Frequently Asked Questions
- Is the Corally Sport Racing 50C LiPo battery suitable for beginner RC car enthusiasts? — Whilst this battery is designed for performance-focused racing applications rather than casual use, it's certainly suitable for beginners who've progressed beyond brushed motors and wish to experience genuine brushless performance. Beginners should ensure they have appropriate 4S-compatible charging equipment and understand LiPo battery safety protocols before use. The hard case protection and robust construction make it more forgiving than delicate soft-pack alternatives.
- What is the maximum current this battery can safely deliver? — The 50C continuous discharge rating means this 5400mAh battery can safely deliver 270 amps of continuous current (5.4Ah × 50C = 270A). The burst discharge capability accommodates brief acceleration demands from brushless motors during competitive racing without voltage sag or safety compromise.
- How long does it take to charge the Corally Sport Racing 50C battery? — With a maximum charge rate of 3C (16.2 amps), you can fully charge the 5400mAh battery in approximately 20 minutes using a compatible 3C charger. Many RC enthusiasts use 2C charging (10.8 amps, approximately 30 minutes) for optimal battery longevity. Always use a charger featuring proper LiPo balancing functionality.
- What makes Corally LiPo batteries different from other 4S racing batteries available in the UK? — Team Corally distinguishes itself through manufacturing in a specialised factory with 15+ years' lithium-polymer expertise, meticulous individual cell testing and balancing, rigorous quality control processes, and a new formulation that maximises cycle-to-cycle performance consistency. Competing budget batteries often skip these quality steps, resulting in inferior power delivery, shorter lifespan, and potential safety compromises.
- Is this battery compatible with my RC car's existing ESC and receiver setup? — The 4S LiPo 14.8V configuration works with any ESC and receiver rated for 4S battery systems. Check your equipment documentation for "4S" or "LiPo" compatibility before use. The XT90 connector is a professional standard, though you may need an adaptor if your vehicle uses a different connector type.
- What storage requirements do LiPo batteries need? — Store LiPo batteries in a cool, dry location away from direct sunlight. For extended storage (weeks or months), charge to approximately 50% capacity and store in a fireproof container or LiPo safety bag. Never store fully charged or fully discharged; partially charged batteries experience minimal self-discharge and maintain optimal long-term health.
- Can I use multiple Corally Sport Racing 50C batteries in parallel for longer runtime? — Whilst parallel battery configuration is technically possible, it requires specialist knowledge and proper balance charging infrastructure. We recommend consulting advanced RC racing forums or contacting our team for guidance before attempting parallel battery configurations.
