Key Features

• 50C Continuous Discharge Rate — This high discharge capability delivers powerful, consistent current to your motor and ESC, allowing your RC car to maintain peak performance during aggressive driving, racing scenarios, and full-throttle acceleration without voltage sag that would otherwise hamper your vehicle's speed and responsiveness.
• 5400mAh Capacity — The substantial 5400mAh capacity provides extended runtime between charges, allowing you to enjoy longer driving sessions and more time on the track before needing to return to the charger, which is essential for competitive racing and serious bashers.
• 3S Configuration (11.1V Nominal) — This three-cell lithium polymer configuration delivers the optimal voltage balance for most modern 1/10-scale and 1/8-scale RC cars, providing excellent power delivery whilst remaining compatible with standard ESC and motor setups found in competitive and recreational RC vehicles across the UK.
• Hard Case Construction — The rigid hard case protects your battery from physical damage, punctures, and deformation during transport and storage, ensuring the battery maintains its structural integrity and remains safe for use in demanding conditions.
• T-Plug Connector with Hardwire Configuration — The T-Plug (Deans connector) provides a secure, low-resistance connection to your ESC, whilst the hardwire configuration (with pre-soldered 12 AWG silicone wires measuring approximately 100mm) eliminates the need for additional connectors and reduces connection resistance for maximum power transfer efficiency.
• JST-XH 3S Balance Connector — The integrated balance connector with JST-XH 3S configuration allows proper cell balancing during charging, ensuring all three cells maintain equal voltage and maximising battery lifespan and safety during every charge cycle.
• Premium Cell Selection and Matching — Each cell undergoes meticulous balancing, aging, grading, and matching based on voltage and internal resistance before assembly, guaranteeing that only the highest-grade cells with minimal tolerances between individual cells are used, resulting in unparalleled performance and well-balanced output.
• Up to 3C Maximum Charge Rate — The battery supports charge rates up to 3C (16.2A maximum charge current), allowing relatively quick recharging without compromising battery lifespan, making it convenient for competitive environments where turnaround time between races is critical.
• Silicone Wire Construction — Both the power wires (12 AWG) and balance wires (22 AWG) are constructed from flexible silicone insulation, providing superior heat resistance, durability, and flexibility compared to standard vinyl-coated wires, particularly important during high-discharge scenarios where heat generation is a concern.
• Compact Stick Form Factor — The stick-shaped design (138mm length × 47mm width × 48mm thickness) fits neatly into most RC car battery trays and compartments without requiring significant modification, making installation straightforward for both new and experienced builders.
• Industry-Leading Manufacturing Standards — Manufactured to exacting standards by a factory with over 15 years of specialist experience in high-discharge lithium polymer batteries, the C-49445 benefits from proven manufacturing processes that prioritise safety, consistency, and performance across every unit produced.

Technical Performance

The Corally Sport Racing 50C LiPo Battery delivers impressive technical specifications that make it suitable for a wide range of electric RC applications. With a continuous discharge rating of 50C, this battery pack can safely deliver up to 270 amps of continuous current (5400mAh × 50C ÷ 1000), providing the sustained power necessary for high-performance brushless motors and racing-grade electronic speed controllers. The 11.1V nominal voltage (3S configuration) represents the industry standard for modern 1/10-scale and 1/8-scale electric RC cars, buggies, and trucks, delivering the perfect balance between motor performance and ESC compatibility. The battery's lightweight construction at 587 grams (without wires) ensures minimal mass penalty whilst maximising your RC vehicle's power-to-weight ratio—a critical factor in competitive racing where every gram impacts acceleration, handling, and overall performance.

The engineering excellence evident in the C-49445 extends to its internal resistance characteristics and cell matching precision. By subjecting each individual cell to rigorous balancing, aging, grading, and matching processes before assembly, Corally ensures that voltage distribution across the three cells remains uniform, preventing the imbalanced discharge that would otherwise reduce overall battery capacity and lifespan. The JST-XH 3S balance connector facilitates proper cell balancing during every charge cycle, actively maintaining this voltage equilibrium and extending the battery's useful life considerably beyond typical low-grade hobby batteries. The silicone wire construction with 12 AWG power conductors and 22 AWG balance conductors provides exceptional durability and heat dissipation characteristics, critical when pushing the battery to its 50C continuous discharge limits during intense competition or high-speed bashing sessions.

Frequently Asked Questions

• Is the Corally Sport Racing 50C LiPo battery compatible with my 1/10-scale RC buggy? — Yes, this battery is specifically designed for 1/10-scale and similar-sized RC cars, buggies, trucks, and off-road vehicles. The 11.1V (3S) voltage is the industry standard for these vehicles, and the T-Plug connector is widely compatible with modern ESCs. However, always verify that your ESC supports 3S LiPo batteries and that your vehicle's battery tray can accommodate the 138 × 47 × 48mm dimensions before purchasing.
• How long will this battery last on a single charge? — Runtime depends entirely on your motor, ESC programming, driving style, and terrain. The 5400mAh capacity provides substantial runtime, typically ranging from 15 to 25 minutes of continuous high-performance driving for most 1/10-scale electric RC cars, though conservative driving can extend this considerably. For accurate runtime estimates, consult your motor and ESC specifications.
• What charger do I need for this battery? — You'll need a LiPo-capable charger that supports 3S batteries and can deliver up to 3C charge current (16.2A maximum). Most modern balance chargers with LiPo settings will work perfectly, and the JST-XH 3S balance connector allows you to charge all three cells simultaneously, ensuring proper voltage equalisation and optimal battery health.
• Can I use this battery in a beginner's RC car? — Whilst the Corally Sport Racing battery is suitable for all skill levels, it's designed for moderate to advanced users who understand LiPo battery safety protocols. Beginners should ensure they have appropriate charging equipment, understand safe storage procedures, and follow all safety guidelines included with the battery. If you're new to LiPo batteries, we recommend consulting our RC experts before your first purchase.
• How does the 50C rating compare to lower C-rated batteries? — The 50C continuous discharge rating means this battery can safely deliver 50 times its capacity in amps per second (270A for this 5400mAh pack). Higher C ratings allow sustained high-performance driving without voltage sag, providing better acceleration, top speed, and responsiveness compared to lower C-rated batteries, making this ideal for racing and serious bashers.
• What makes Corally batteries different from cheaper alternatives? — Corally batteries undergo meticulous quality assurance including individual cell balancing, aging, grading, and precise matching based on voltage and internal resistance. Only the highest-grade cells are assembled into packs, ensuring minimal variation between cells, superior performance consistency, extended cycle life, and enhanced safety compared to low-grade hobby batteries.
• Is this battery waterproof for use in wet conditions? — The hard case provides splash protection, but Corally LiPo batteries are not fully waterproof. Whilst some water exposure is tolerable, submersion or prolonged wet conditions can damage internal components. Always allow the battery to dry completely before charging if it gets wet, and avoid intentional waterside use without proper protection.
• How should I store this battery for maximum lifespan? — Store your Corally LiPo battery in a cool, dry location (ideally 15-25°C) at approximately 3.8V per cell (around 11.4V total). Charge to storage voltage before extended storage periods, avoid extreme temperatures, and never store in direct sunlight or damp environments. Proper storage can significantly extend battery lifespan and maintain performance consistency.
