Frequently Asked Questions

• What is LiHV battery chemistry and why is it better for my RC car? — LiHV (Lithium High Voltage) chemistry operates at 4.35V per cell instead of the standard 3.7V, delivering significantly higher energy density and more consistent voltage delivery throughout the discharge cycle. This means your RC car experiences better performance, longer runtime per charge, and the ability to maintain peak power output right until the battery reaches its safe voltage limit, making it ideal for competitive racing and aggressive bashing applications.
• Is this 2S LiPo battery compatible with my RC car? — This 2S 7.6V battery is compatible with any RC car designed for 2S LiPo power, which includes numerous 1/10 scale and smaller vehicles. Specifically, it's engineered for models including Traxxas Senton 3S, BIG ROCK 3S BLX, and various 1/7 scale platforms like FELONY 6S BLX, LIMITLESS, and INFRACTION 6S BLX. Always verify your specific RC car model's battery requirements before purchase, and ensure your charger supports 2S LiPo batteries.
• What charger do I need for this Gens Ace smart battery? — This battery features G-Tech smart chip technology and works perfectly with the G-Tech Eco Smart Charger for optimised charging with automatic identification and communication. However, it's fully compatible with any standard RC LiPo charger available in the UK, giving you complete flexibility whether you're using dedicated smart chargers or conventional balancing chargers. Always use a proper LiPo charger and never attempt to charge LiPo batteries with non-LiPo chargers.
• What does the 100C discharge rating mean for RC car performance? — The 100C rating indicates that this 5500mAh battery can safely discharge at 550 amps continuously (5500mAh × 100C = 550A), making it suitable for high-performance brushless motors that demand massive current flow. This rating allows your RC car to achieve maximum acceleration, top speed, and power delivery without voltage sag, making it ideal for competitive racing, speed runs, and aggressive bashing scenarios where consistent power is critical.
• How does the self-storage mode work and why is it important? — The integrated self-storage mode automatically adjusts the battery's voltage to an optimal level for long-term storage, protecting the LiPo cells from damage during periods of inactivity. This feature significantly extends your battery's lifespan if you need to store your RC car for weeks or months, as stored batteries at full charge degrade faster than those maintained at storage voltage levels.
• What is the weight and will it affect my RC car's performance? — At 290 grams, this battery is specifically engineered for RC cars that require this capacity level. The hard-case construction places the battery's centre of gravity low in the chassis, actually improving handling and stability rather than hindering it. The weight is balanced by the high energy output, meaning you get longer runtime and better performance than lighter but less powerful alternatives.
• Is this battery good for beginners in the RC car hobby? — This is an advanced battery suitable for hobbyists with some RC experience rather than complete beginners. The high-voltage chemistry and 100C rating make it ideal for serious enthusiasts, competitive racers, and aggressive bashers. Beginners might prefer standard LiPo batteries or pre-assembled ready-to-run RC car packages. However, if you're upgrading an existing RC car or purchasing this battery alongside compatible equipment, it provides excellent value and performance for growing into the hobby.
• What makes the XT60 connector better than other connectors? — The XT60 is an industry-standard connector in RC cars, offering large contact surfaces that handle high current with minimal resistance and heat generation. The design creates a secure mechanical connection that won't accidentally disconnect during driving, and the connector is widely available across UK RC retailers, making it easy to find compatible equipment, chargers, and adapters.
