Key Features

• 3300mAh Capacity — This substantial capacity provides extended runtime for RC helicopters, planes, boats and cars, allowing you to enjoy longer sessions between charges without the constant need to rotate batteries.
• 2S Cell Configuration (7.4V) — The two-cell series arrangement delivers a nominal voltage of 7.4V, which is optimal for a vast range of mid-sized RC models and provides excellent power delivery characteristics for both acceleration and sustained performance.
• 30C Discharge Rating — This 30C rating means the battery can safely discharge at 99 amps (3300mAh × 30), making it suitable for models requiring consistent, reliable power without the battery becoming a limiting factor in performance.
• XT60 Connector — The industry-standard XT60 connector ensures broad compatibility with most modern RC equipment, chargers and ESCs, making this battery a versatile addition to any RC enthusiast's fleet.
• Low Internal Resistance (Low IR) — The specially engineered chemistry provides stable voltage until the end of your mission, meaning you maintain consistent power throughout the entire discharge cycle rather than experiencing the voltage sag common in lower-quality batteries.
• Compact and Lightweight Design — At just 172 grams with dimensions of 134 x 43 x 13mm, this battery is slim enough to fit in restrictive battery compartments whilst maintaining excellent energy density and performance.
• G-Tech Chemistry — Gens Ace's proprietary G-Tech formula offers improved energy density specifically adapted to various RC types including UAVs, RC cars, boats and helicopters, ensuring optimal performance across different applications.
• Recommended 1-3C Charge Rate — This flexible charging specification means you can charge the battery relatively quickly without compromising cell longevity, allowing for convenient turnaround between flights or runs.
• Stable Simultaneous Discharge Technology — Gens Ace batteries are engineered to maintain stable discharge across multiple cells, preventing the imbalance and voltage irregularities that can occur in lesser-quality packs.
• ISO-Certified Manufacturing — Every cell and component meets ISO9001 and ISO14001 standards, meaning you're purchasing from a manufacturer with rigorous quality control and environmental responsibility.

Technical Performance

The Gens Ace Soaring 3300mAh represents a carefully engineered balance between capacity, discharge capability and physical size. With a 30C discharge rating of 99 amps maximum, this battery is well-suited to mid-range RC applications where sustained power delivery matters more than peak current output. The 7.4V nominal voltage places this squarely in the sweet spot for most 2S-compatible RC cars, helicopters, planes and boats, providing excellent voltage characteristics across the discharge curve. Built from high-quality lithium polymer cells selected by Gens Ace's team of 200 professional engineers and technicians, the pack features specially formulated chemistry that maintains stable voltage throughout your entire mission thanks to low internal resistance. The weight of 172 grams is competitive for a 3300mAh pack, and the compact profile of 134 x 43 x 13mm means it fits into space-constrained battery compartments without requiring extensive vehicle modifications. The XT60 connector is the industry standard for modern RC equipment, ensuring immediate compatibility with most contemporary ESCs, chargers and balance plugs. Gens Ace has engineered this battery with very high energy density according to capacity-to-weight ratio, meaning you get maximum runtime relative to the weight penalty—a crucial consideration for aircraft, helicopters and weight-sensitive RC boats. The recommended 1-3C charge rate provides flexibility: charge at 1C (3.3A) for a leisurely overnight charge, or push to 3C (9.9A) for faster turnaround when you're keen to get back into action.

Frequently Asked Questions

• What RC models are compatible with a 2S 7.4V LiPo battery in the UK? — This 2S battery is suitable for a wide range of mid-sized RC models including Traxxas Slash, E-REVO, Rustler and Caster SK-10. It's also compatible with most RC helicopters, RC planes, RC boats and mid-range RC cars UK retailers stock. Check your vehicle's manual to confirm it accepts 2S batteries—most 1/10 scale vehicles and larger helicopters support this voltage.
• Is the Gens Ace Soaring 3300mAh battery suitable for beginners? — Yes, absolutely. The 30C discharge rating is forgiving and reliable, meaning it won't deliver dangerously high current spikes that could damage a beginner's ESC or motor. The XT60 connector is industry standard and easy to use. As long as your RC model is designed for 2S LiPo batteries, this is an excellent beginner-friendly choice that delivers quality performance without the frustration of a poorly-performing battery.
• What charger do I need for a 2S LiPo battery? — You'll need an LiPo-compatible charger with 2S balance charging capability. Most modern RC chargers support 2S packs. The recommended charge rate is 1-3C, meaning you can charge this 3300mAh battery at between 3.3 amps (1C, slower) and 9.9 amps (3C, faster). Always use a charger with LiPo cell balancing to maintain equal voltage across both cells and extend battery life.
• How long is the runtime on the Gens Ace 3300mAh battery? — Runtime depends entirely on your RC model's power consumption. A typical mid-range RC car might achieve 15-20 minutes of continuous use, while lighter RC planes or helicopters could fly for 20-30 minutes. Check your vehicle's manual for estimated run times with a 3300mAh 2S pack, or calculate based on your vehicle's typical current draw.
• What is the difference between the 30C and higher discharge ratings? — A 30C battery can safely discharge at 99 amps (3300mAh × 30). Higher C ratings like 50C or 100C allow greater maximum current discharge, which benefits high-performance racing vehicles or extreme 3D flight applications. For general-purpose flying and driving, the 30C rating is more than sufficient and offers excellent value.
• Can I use this battery in my Traxxas Slash? — Yes, the Gens Ace 2S 7.4V is ideal for Traxxas Slash models. Traxxas Slash was specifically mentioned as a recommended platform for this battery. Simply ensure your Slash is equipped with an ESC and motor compatible with 2S LiPo (most Slash variants are), connect the XT60 connector, and you're ready to bash.
• What does the 172-gram weight mean for my RC model? — The 172-gram weight is relatively light for a 3300mAh pack, making it ideal for weight-sensitive applications like RC planes, helicopters and boats. For RC cars, the weight is negligible and won't affect handling. Always ensure your vehicle's battery compartment is designed to accommodate the pack's dimensions of 134 x 43 x 13mm.
• Is this battery waterproof for RC boats? — LiPo batteries should never be immersed in water. However, this battery is suitable for RC boats provided it's housed in a waterproof battery box or compartment. The XT60 connector and balance lead are not waterproof, so ensure these are kept dry during operation.
