Frequently Asked Questions

• Is the Gens Ace G-Tech 8500mAh suitable for Traxxas X-Maxx and ARRMA Kraton 8S vehicles? — Yes, the manufacturer specifically recommends this battery pack for Traxxas X-Maxx, Traxxas Sledge, and ARRMA Kraton 8S. The 14.8V 4S configuration and 8500mAh capacity are optimised for these high-performance 1/5 and 1/8 scale platforms, delivering the power and runtime they demand.
• What does a 60C discharge rate mean for my RC car performance? — The 60C discharge rate indicates the maximum continuous current the battery can safely deliver, calculated by multiplying capacity by the C-rate (8500mAh × 60 = 510A maximum). This true 60C rating ensures rapid acceleration, responsive throttle control, and stable voltage delivery under extreme driving conditions, whether you're racing on track or bashing across rough terrain.
• How long will the 8500mAh battery last on a single charge? — Runtime depends on your specific vehicle, driving style, and throttle usage. Generally, larger capacity batteries like this 8500mAh pack provide longer run times than smaller alternatives, allowing extended driving sessions before requiring recharge. Aggressive driving and higher throttle settings will reduce runtime compared to conservative driving.
• Is the hard case necessary? — Yes, the PC material hard case provides important protection against impact damage during off-road driving and rough terrain use. The hard case also ensures secure fitment within your vehicle's battery tray, preventing movement and potential short circuits during aggressive manoeuvres. The rugged construction extends battery lifespan significantly compared to soft-case alternatives.
• What charger do I need for this battery? — This battery requires a LiPo-compatible charger capable of charging 4S (14.8V) packs. Standard hobby-grade LiPo chargers are widely available from RC retailers across the UK. For optimal results and safety, use a dedicated LiPo charger rather than attempting charge with standard power supplies.
• Can I use this battery with other RC vehicles? — The 14.8V 4S configuration makes this battery compatible with other 4S-compatible RC vehicles, though the 8500mAh capacity is specifically suited to larger 1/5 and 1/8 scale platforms. Always verify your vehicle manufacturer's specifications before using with any RC model not explicitly listed in the compatibility guide.
• What safety precautions should I take with this LiPo battery? — LiPo batteries require careful handling. Always charge on a fireproof surface, never leave charging unattended, store in a cool dry place, and use appropriate storage voltage (approximately 3.85V per cell). Inspect the battery before each use for damage, puffing, or swelling. If the battery shows any signs of damage or malfunction, discontinue use immediately.
• How does the XT90 connector benefit my RC setup? — The XT90 connector is an industry standard designed for high-current discharge applications. It provides superior conductivity compared to older connector types, minimising voltage drop and maximising power transfer efficiency to your brushless ESC. The secure mechanical design ensures reliable connection stability during aggressive driving sessions.
