Technical Performance

The Gens Ace Soaring 2S 7.4V 3300mAh 30C battery represents the pinnacle of reliable mid-range LiPo technology for RC applications throughout the UK and beyond. The engineering behind this pack focuses on balancing three critical performance factors: capacity, discharge capability, and weight efficiency. At 3300mAh capacity with a 7.4V nominal voltage (delivered across two LiPo cells in series), the battery pack provides 24.42 watt-hours of total energy, sufficient to power most RC vehicles for 15 to 45 minutes depending on the model's power draw and motor efficiency. The 30C continuous discharge rating means the pack will safely deliver up to 99 amps of steady-state current, whilst the 60C burst capability accommodates the peak current demands that occur during acceleration, climbing, or high-throttle manoeuvres. This dual-rating approach ensures the battery performs reliably during sustained operations (where 30C continuous rating applies) whilst providing headroom for dynamic performance (where 60C burst rating kicks in). The low internal resistance characteristic of Gens Ace's manufacturing process means voltage remains stable throughout the discharge curve, preventing the gradual performance degradation that occurs with lower-quality batteries as they deplete. The compact dimensions of 132.5 x 42 x 13.5mm allow this pack to fit into vehicles and aircraft where space is at a premium, whilst the 186-gram weight keeps overall model weight low, improving acceleration, handling response, and flight characteristics. The XT90 connector is engineered with gold-plated contacts to minimise resistance and heat generation, ensuring maximum power transfer to your RC model's motor and electronics. Whether you're powering an RC car, RC boat, RC helicopter, or fixed-wing RC plane, this battery pack delivers the combination of performance, reliability, and build quality that distinguishes Gens Ace as one of the world's leading battery manufacturers in the RC hobby sector.

Frequently Asked Questions

• Is the Gens Ace Soaring 2S 3300mAh battery suitable for beginners in RC? — Yes, absolutely. The 2S format with 7.4V is one of the most popular entry-level battery configurations in the RC hobby, offering straightforward charging requirements and broad compatibility with beginner-friendly models. The 30C discharge rate is more than adequate for standard RC vehicles and aircraft, and the battery is forgiving enough for new pilots and drivers to learn with confidence. If you're new to RC and wondering whether to choose 2S or 3S LiPo, the 2S format is typically easier to manage and safer for learning.
• What RC models is this 2S LiPo battery compatible with? — The Gens Ace Soaring 2S pack is suited to a wide variety of RC models including Traxxas Slash, Traxxas E-REVO, Traxxas Rustler, Caster SK-10, and numerous other RC cars, RC helicopters, RC planes, and RC boats that accept 2S LiPo batteries with XT90 connectors. Before purchase, verify that your specific model supports 2S voltage (7.4V nominal) and XT90 connector compatibility to ensure perfect fitment.
• How long does it take to charge the Gens Ace Soaring 3300mAh battery? — With a recommended charge rate of 1-3C, the battery will fully recharge in approximately 20 to 60 minutes depending on which end of the charge rate spectrum you use. At 1C (3.3 amps), charging will take about 60 minutes. At 3C (9.9 amps), charging will take about 20 minutes. Always use a quality LiPo charger with balance charging capability to ensure cell voltage balance and battery longevity.
• What is the difference between the 30C continuous and 60C burst discharge ratings? — The 30C continuous rating means the battery can safely deliver 30 times its capacity (in amps) indefinitely during normal operation. The 60C burst rating means it can deliver twice that current for short periods during peak demand moments such as rapid acceleration. Together, these ratings indicate the battery is well-suited to dynamic RC applications where power demands fluctuate throughout a flight or drive session.
• Does the XT90 connector differ from other battery connectors? — The XT90 is one of the most widely adopted connectors in modern RC applications, featuring gold-plated contacts and a secure fit that minimises connection resistance. It's distinctly different from older XT60 connectors (which are smaller) and from Tamiya connectors. Ensure your RC vehicle's ESC and charger both feature XT90 connectivity before purchasing, or plan to use an adapter.
• What makes Gens Ace batteries different from cheaper alternatives? — Gens Ace has 20 years of dedicated battery manufacturing expertise and employs 200 professional engineers and technicians in battery research and development. The company manufactures NiMH, Li-Po, and Li-Fe batteries across an enormous range of scales and applications. This Soaring series specifically is engineered for consistency, with low internal resistance, stable voltage output, and strict quality control. Gens Ace batteries are ISO9001 and ISO14001 certified, meaning they meet internationally recognised standards for quality and environmental responsibility that many cheaper batteries do not.
• Can I use this battery in multiple RC models? — Yes, provided each of your RC models is compatible with 2S 7.4V batteries with XT90 connectors, this single pack can power them all. Many RC enthusiasts with multiple vehicles (such as an RC car and an RC helicopter) choose to own several 2S batteries so they can rotate them through their fleet without waiting for recharging between sessions.
• How should I store this battery when not in use? — LiPo batteries should be stored in a cool, dry place, ideally at a partial state of charge (around 50%) if storage will exceed a few weeks. Avoid storing at full charge or fully depleted. The protective soft case included with this pack provides basic protection during storage. Many UK RC enthusiasts also use dedicated LiPo storage boxes or bags as an additional safety precaution.
• Is the Gens Ace Soaring 2S battery waterproof? — No, this is a standard LiPo battery pack and should not be immersed in water. Whilst it's safe to use in RC boats where the battery is housed inside a waterproof compartment of the model, the battery itself is not waterproof and must be kept dry during storage and charging.
