Frequently Asked Questions

• What is a 120C discharge rate and why does it matter for my RC car? — The 120C rating indicates the maximum safe continuous current this battery can deliver, calculated as the capacity in amp-hours multiplied by the C rating. For this 4200 mAh battery, 120C means it can safely deliver 504 amps continuously. This high discharge capability is essential for modern brushless RC cars, as it allows the motor and ESC to draw maximum power without the battery becoming a performance bottleneck, ensuring you achieve peak acceleration and maintain voltage stability during intense racing.
• Is the Corally Voltax 120C suitable for beginners? — This battery is specifically designed for competitive and experienced RC enthusiasts rather than beginners. The high discharge rate and performance characteristics are most beneficial in racing scenarios where maximum power and consistency are required. Beginners typically use lower C-rated batteries that are more forgiving. However, if you're stepping up from casual bashing to serious RC car racing, this battery is an excellent choice that will grow with your skills.
• What charge rate should I use and how long does it take to charge? — This battery supports charge rates up to 3C, which means a maximum charge current of 12.6 amps. Charging at the full 3C rate will charge the battery in approximately 20 minutes, whilst charging at a slower 1C rate (4.2 amps) will take about 60 minutes. Using a quality lithium balance charger and not exceeding 3C ensures optimal cell health and longevity. Always monitor your battery during charging and allow it to cool before use.
• What makes Team Corally batteries different from other RC batteries? — Team Corally batteries are manufactured at a prestigious facility with over 15 years of experience in high-discharge lithium polymer technology.
