• 5400mAh Capacity — The 5400 milliamp-hour capacity provides extended runtime between charging cycles, allowing you to enjoy longer play sessions and more practice laps at your RC track without needing to swap batteries as frequently as you might with lower-capacity packs.
• 14.8V Four-Cell Configuration (4S) — The four lithium polymer cells in series deliver 14.8 volts nominal output, providing the voltage level required by most modern ESC and motor combinations used in competitive RC racing setups, from 1/10-scale buggies to larger touring cars.
• EC5 Power Connector — The industry-standard EC5 connector provides a secure, reliable electrical connection with low resistance, ensuring maximum current transfer efficiency and minimising voltage sag during peak power demands, which is critical for maintaining consistent throttle response.
• Stringent Quality Control — Every individual cell is carefully tested for voltage balance, internal resistance, aged and precisely sorted before assembly into Team Corally battery packs, guaranteeing that only the highest-quality cells with minimal tolerance variations enter the final product, resulting in perfectly balanced packs with extended lifespan.
• JST-XH 4S Balance Connector — The four-pin balance connector allows your battery charger to monitor and equalise voltage across each individual cell during charging, preventing cell imbalance issues that can reduce battery lifespan and performance over time.
• Silicone-Sheathed Wiring — The battery features 12 AWG silicone-insulated main power wires with 22 AWG balance lead wires, providing excellent flexibility and durability whilst maintaining safe current-carrying capacity for racing applications.
• Up to 3C Charge Rate Capability — The battery can be charged at rates up to 3C (16.2 amps), which means you can fully recharge this pack in approximately 20 minutes using a suitable charger, enabling quick turnarounds between practice sessions.
• Hard Case Protection — The rigid plastic stick case provides physical protection during transport and storage, safeguarding the delicate lithium cells from mechanical damage whilst keeping the battery in optimal condition between uses.
• Extended Cycle Life — Thanks to the advanced cell formulation and rigorous quality assurance processes, this battery maintains consistent performance across significantly more charge-discharge cycles compared to budget alternatives, delivering better value over the lifetime of the product.

Technical Performance

The Corally Power Racing 50C battery combines sophisticated engineering with proven manufacturing expertise to deliver uncompromising performance for demanding RC applications. At 5400mAh capacity with a continuous 50C discharge rate, this pack produces 270 amps of sustained current output, making it ideally suited for high-performance RC cars, boats and aircraft where consistent power delivery is critical for competitive racing. The four lithium polymer cells are configured in series to produce 14.8 volts nominal output, perfectly matching the voltage requirements of modern brushless motor and ESC combinations commonly found in 1/10-scale racers and similar sized vehicles throughout the UK and internationally. The battery measures 138mm in length, 47mm in width and 48mm in height, offering a compact stick profile that fits efficiently into most modern RC vehicles without requiring significant chassis modifications. The total weight remains unspecified in technical data, though the lightweight construction philosophy ensures minimal impact on overall vehicle weight compared to bulkier battery alternatives. The EC5 power connector and balance wiring configuration ensure safe, reliable electrical connections with minimal voltage drop during peak current draw. The silicone-insulated 12 AWG main power wires (approximately 100mm in length) and 22 AWG balance wires provide both safety and durability for competitive racing environments, whilst the Up to 3C charge rate capability enables rapid recharge cycles using compatible lithium polymer battery chargers.

Frequently Asked Questions

• Is the Corally Power Racing 50C battery suitable for my RC racing setup? — This battery is specifically designed for high-performance racing applications where sustained power output is essential. If your RC car, boat or aircraft uses an EC5 power connector and supports 4S lithium polymer batteries (14.8V nominal), this pack will provide excellent performance. Check your vehicle's specifications to confirm compatibility before purchasing.
• How long will this battery last during racing or flying? — Runtime varies significantly depending on your specific vehicle's motor, ESC settings, driving style and terrain conditions. Generally, a 5400mAh battery provides 15-25 minutes of continuous use in competitive racing scenarios, though casual flying applications may experience longer runtimes. High-performance racing typically generates higher current draw, resulting in shorter runtime but superior acceleration and speed response.
• What is the difference between the 50C and 60C discharge rates? — The discharge rate (C rating) indicates maximum safe current output. A 50C battery can safely deliver 270 amps continuously (50 × 5.4), whilst a 60C pack would deliver 330 amps. The higher 60C rating provides more headroom for extreme acceleration and peak power scenarios, though 50C remains perfectly adequate for most competitive RC racing applications. Your choice should match your vehicle's maximum current requirements.
• How do I safely charge this 4S LiPo battery? — Use only a dedicated lithium polymer battery charger with a JST-XH 4S balance connector. The battery supports up to 3C charge rates, meaning 16.2 amps maximum, which achieves full recharge in approximately 20 minutes. Always use a LiPo-compatible charger set to correct voltage (14.8V) and capacity (5400mAh) settings. Never attempt to charge using standard lead-acid or NiMH chargers.
• What makes Team Corally batteries more reliable than budget alternatives? — Team Corally implements rigorous quality control processes that begin before manufacturing. Every individual cell is tested for voltage balance, internal resistance, aged and sorted according to strict tolerance specifications. Only the highest-quality cells with minimal variation between units are selected for assembly, guaranteeing perfectly balanced packs with consistent performance across numerous charging cycles. This manufacturing discipline significantly extends lifespan and reliability compared to budget batteries that skip these quality assurance steps.
• Can I use this battery in saltwater RC boats or wet environments? — Whilst the battery itself contains no external waterproofing, lithium polymer packs tolerate moisture exposure better than many alternatives. However, you should always protect the EC5 connector from saltwater immersion and rinse the battery with fresh water immediately after saltwater use. For extended saltwater operation, consider using a protective battery bag or waterproof enclosure within your vehicle.
• How should I store this battery when not in use? — Store the Corally Power Racing battery in its protective hard case in a cool, dry location away from direct sunlight. For extended storage periods exceeding two weeks, partially discharge the pack to approximately 50% state of charge (around 7.4V resting voltage), as fully charged lithium cells experience minor capacity degradation during storage. Check cell voltages monthly and top up if individual cells drop below 3.6V per cell.
• Is this battery suitable for beginners in the RC hobby? — Whilst technically robust and reliable, this 50C battery is primarily designed for competitive racing applications rather than beginner-level vehicles. Beginners should verify that their specific RC car or aircraft supports 4S LiPo batteries and EC5 connectors before purchasing. If you're new to the RC hobby, consult your vehicle's manual or contact our expert team at RC Model Shop for guidance on compatible power sources.
