Technical Performance

The Corally Voltax 120C LiPo HV Battery represents the absolute pinnacle of lithium polymer battery engineering for high-performance RC car applications. The combination of 120C continuous discharge capability with 6500 mAh capacity and 15.2V nominal voltage creates a battery pack that delivers sustained peak performance throughout your driving session. The LiHV (Lithium High Voltage) chemistry with 3.8V per cell is specifically engineered for the latest generation of brushless ESCs and high-KV brushless motors that thrive on elevated voltage supplies. Modern brushless motor systems are designed to extract maximum efficiency and power from higher voltage supplies, and the 15.2V nominal output of this 4S LiPo pack delivers precisely the voltage these systems require. The 584-gram weight provides a substantial energy-to-weight ratio that ensures adequate power without unnecessary mass penalty. The continuous discharge rate of 120C means the battery can sustain 780 amps of current delivery indefinitely during normal use, providing the instantaneous power required by competitive motors and ESCs without the voltage sag that characterises inferior batteries. The hard case construction protects the internal cell structure from physical damage whilst the stick configuration fits standard battery trays in most RC car designs. The XT90 connector with 12 AWG silicone wire is engineered specifically for the high-current demands of this battery, minimising voltage drop and ensuring maximum power reaches your motor. The JST-XH 4S balance connector enables your charger to monitor and balance each individual cell independently, a critical feature for maintaining cell health across numerous charge cycles and extending overall battery lifespan. The meticulous quality assurance process ensures that every cell is graded and matched before assembly, meaning you receive a perfectly balanced pack where all four cells are at nearly identical internal resistance and voltage characteristics, critical for consistent performance and safety.

Frequently Asked Questions

• Is the Corally Voltax 120C suitable for high-performance RC car racing? — Absolutely. The 120C continuous discharge rate and LiHV chemistry make this battery specifically designed for competitive RC car racing where maximum power output and reliability are essential. The battery is EFRA and BRCA competition approved, confirming it meets official racing standards across the UK and Europe.
• What is the difference between standard LiPo and LiHV chemistry? — LiHV (Lithium High Voltage) chemistry operates at 3.8V per cell compared to 3.7V per cell in standard LiPo, resulting in a nominal pack voltage of 15.2V for 4S versus 14.8V. The higher voltage delivers more power and torque to your motor throughout the discharge cycle. LiHV batteries require specific chargers capable of handling the higher cell voltage, typically balancing chargers with LiHV charging profiles.
• How long will the battery last on a single charge? — Runtime depends on your specific motor, ESC, gear ratio, and driving style. The 6500 mAh capacity provides substantial energy storage. A typical competitive RC car running a high-power brushless motor might achieve 15-25 minutes of continuous driving, whilst more conservative driving styles could achieve considerably longer runtimes. The low-sag 120C discharge capability means you maintain full voltage and power delivery even during peak acceleration.
• What charger do I need to charge this battery? — You require a charger capable of supporting LiHV chemistry with a JST-XH balance connector and capable of delivering up to 3C charge current (19.5 amps for this pack). Many modern hobby chargers include LiHV profiles. Your charger must support 4S balance charging via the JST-XH connector to ensure all four cells remain perfectly balanced and to maximise battery lifespan.
• Is this battery suitable for beginners? — Whilst this battery is technically suitable for any RC car with a compatible XT90 connector, beginners should understand that LiHV batteries require chargers with specific LiHV charging profiles and carry higher energy density than standard LiPo, requiring careful handling and storage. Experienced RC car drivers appreciate the superior performance, but beginners might find standard 4S LiPo batteries more straightforward to manage initially.
• How should I store this battery when not in use? — Team Corally LiPo batteries should be stored at room temperature in a safe location, ideally in a dedicated LiPo safety bag. Store at approximately 50% charge state when not using the battery for extended periods. Never leave the battery connected to your vehicle for prolonged periods, as this can cause the cells to discharge unevenly. Proper storage extends cycle life considerably.
• What makes Team Corally batteries different from other brands? — Team Corally batteries are manufactured at a facility with over 15 years of specialist experience in high-discharge lithium polymer batteries. Every individual cell undergoes meticulous balancing, aging, grading, and matching based on voltage and internal resistance before assembly. Only the highest-grade cells with minimal tolerances are used, unlike many hobby batteries that utilise lower-graded cells. This rigorous quality assurance results in superior performance, extended lifespan, and genuine reliability.
• What is the weight and how does this affect my RC car? — The battery weighs 584 grams without the power wires, providing a substantial mass that positions well in most RC car battery trays. Weight placement is critical for handling characteristics, and most RC cars are designed with battery compartments positioned for optimal centre of gravity. Consult your specific RC car's manual for weight recommendations and placement instructions.
• Can I use this battery in other applications besides RC cars? — Whilst designed for RC cars, this battery can technically power any application requiring 15.2V nominal supply with XT90 connectors, including RC planes, RC boats, and RC drones. However, the stick configuration and heavy-gauge wiring are optimised specifically for high-current RC car applications. Always ensure your application is compatible before use.
