• 4200mAh Capacity — The substantial 4200 milliamp-hour capacity provides extended runtime per charge cycle, allowing you to enjoy longer play sessions and more laps during competitive racing before requiring a battery change, ultimately giving you greater enjoyment and value from each charging session.
• 2S LiPo Configuration (7.4V) — The two-cell series configuration delivers 7.4 volts of nominal power, providing an excellent balance of speed and compatibility with the majority of modern RC car ESCs and motor combinations, making this a versatile choice for diverse RC car setups used throughout the UK hobby.
• LCG Shorty Form Factor — The low centre of gravity shorty design positions the battery lower in your chassis for improved handling balance and weight distribution, whilst the compact shorty dimensions ensure excellent packaging compatibility with modern LCG chassis designs that prioritise low, centralised weight placement for superior cornering performance.
• 4mm Bullet Connectors — Gold-plated 4mm bullet connectors provide excellent electrical contact, minimised resistance, and consistent power transfer to your ESC, whilst offering a secure connection that won't accidentally disconnect during dynamic driving or high-load situations.
• 2mm Bullet Balance Connector — The balance connector allows precision cell monitoring and charging, ensuring both cells within the battery pack remain perfectly balanced for optimal performance, extended battery lifespan, and safe charging practices that prevent cell degradation or dangerous imbalances.
• Hard Case Protection — The rigid hard case shell protects your expensive battery investment from physical damage during transport, storage, and handling, preventing the soft lithium cells within from being punctured or compressed, which could compromise safety or create internal shorts.
• Up to 3C Charge Rate — Supporting charge rates up to 3C (12.6 amps for this 4200mAh capacity), this battery charges efficiently without excessive time at the field, allowing you to get back to racing quickly whilst maintaining cell health through controlled, temperature-safe charging practices.
• Rigorous Quality Assurance Process — 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, well-balanced battery packs, and extended life cycles that deliver consistent power throughout the battery's operational lifespan.
• Competition Approved — This battery meets EFRA and BRCA competition standards, making it a legal choice for racing events across the United Kingdom and Europe, ensuring you can use it confidently in sanctioned competitions without worrying about regulatory compliance or disqualification.

Technical Performance

The Corally Voltax 120C battery represents the pinnacle of high-performance LiPo battery engineering, specifically designed for RC cars that demand exceptional power delivery and reliability. At 4200mAh capacity with a continuous discharge rate of 120C, this battery can sustain a continuous discharge current of 50.4 amps, providing more than sufficient electrical capacity for contemporary brushless motor setups used in 1/10 and smaller scale RC cars. The 7.4V nominal voltage perfectly matches standard 2S compatible ESCs and motor systems, ensuring seamless integration into your existing RC car setup. Weighing just 175 grams without the connecting wires, the battery maintains an exceptional power-to-weight ratio that minimises the overall mass burden on your chassis whilst delivering maximum electrical output. The physical dimensions—95mm length, 47mm width, and 22mm height—are precisely calculated to fit within modern low centre of gravity chassis designs that have become the standard for contemporary RC car racing in the UK. The 31.08 watt-hour energy capacity demonstrates the substantial electrical reserves available during demanding driving scenarios. The hard case construction utilises industrial-grade materials that withstand the rigours of competitive use, transport, and storage, whilst the gold-plated 4mm bullet connectors ensure minimal electrical resistance and maximum power transfer efficiency to your ESC. The engineering excellence extends to the internal cell construction, where matching cells with minimal voltage and internal resistance variations prevent premature cell degradation and ensure performance consistency across hundreds of charge cycles, making this battery a genuine long-term investment in reliable RC car power.

Frequently Asked Questions

• Is the Corally Voltax 120C battery suitable for beginners to RC car hobby? — Whilst the Voltax 120C is technically suitable for any RC car with 2S LiPo compatibility, it's primarily engineered for experienced RC enthusiasts and competitive racers who can safely manage and charge high-performance lithium batteries. Beginners should ensure they understand proper LiPo battery safety protocols, including correct charging procedures, safe storage practices, and emergency procedures before using such high-capacity, high-discharge-rate batteries.
• What is the maximum charge current for this battery? — The Corally Voltax 120C supports charge rates up to 3C, which means a maximum charge current of 12.6 amps for this 4200mAh capacity battery. This allows reasonably quick charging without compromising cell health or safety, though many users prefer charging at slightly lower rates (1-2C) to extend overall battery lifespan.
• How long does a full charge take with the recommended charger? — Charging time depends on your charger specifications, but using a 3C charge rate (12.6 amps), a complete charge would theoretically take approximately 20 minutes. However, most quality RC chargers include balance charging and temperature monitoring that may extend this time slightly to ensure optimal cell health and safety.
• What is the difference between this 120C rating and lower C-rated batteries? — The 120C continuous discharge rating means this battery can safely deliver 120 times its capacity in amperage continuously—in this case, 50.4 amps sustained. Lower C-rated batteries (such as 50C or 80C models) would have lower maximum safe discharge currents and might experience voltage sag during high-power demands, resulting in reduced acceleration, speed, and overall performance in demanding racing scenarios.
• Is this battery compatible with my specific RC car? — This battery is compatible with any RC car that accepts 2S LiPo batteries with 4mm bullet power connectors and 2mm bullet balance connectors. You should verify that your ESC and motor combination support the 7.4V nominal voltage and that your chassis has adequate space for the 95mm x 47mm x 22mm form factor. Consult your RC car's manual or contact the manufacturer to confirm compatibility before purchase.
• How should I store this battery when not in use? — Team Corally and all battery manufacturers recommend storing LiPo batteries in a cool, dry location at approximately 50% state of charge (approximately 3.7V per cell). Long-term storage at full charge or completely depleted states can reduce battery lifespan. Store the battery in a fireproof container away from flammable materials, and always monitor for signs of swelling, damage, or abnormal appearance.
• Can I use this battery with a charger that doesn't support balance charging? — Whilst technically possible, balance charging is strongly recommended to maintain cell balance and extend battery lifespan. Without balance charging, individual cells within the pack can develop voltage imbalances over time, compromising performance and potentially creating safety hazards. Modern LiPo chargers almost universally support balance charging through the 2mm balance connector provided with this battery.
