Key Features

• 30C Continuous Discharge Rate — The 30C rating means this battery can safely deliver 99 amps of continuous current (3300mAh × 30C = 99A), providing the sustained power necessary for aggressive manoeuvres, rapid acceleration, and demanding flight regimes without voltage sag or performance degradation.
• 60C Burst Discharge Capacity — For peak power demands, the battery can handle 60C burst discharge (198A maximum), enabling explosive acceleration and dynamic performance during critical flight moments when you need instantaneous throttle response.
• 4S1P Configuration (14.8V) — The four-cell series arrangement delivers 14.8V nominal voltage (16.8V fully charged), providing ample voltage headroom for efficient motor operation and eliminating the need for voltage regulators in most RC applications, whilst the single parallel cell ensures balanced charging and reliable performance.
• 3300mAh Capacity — This capacity strikes an excellent balance between runtime and weight, offering sufficient energy for meaningful flight duration without the excessive weight penalty of larger capacity batteries, making it perfect for aircraft designs that prioritise performance and manoeuvrability.
• Low Internal Resistance (Low IR) — The G-Tech Soaring battery features Gens Ace's proprietary low IR technology, which means the battery maintains stable voltage output throughout your entire flight mission, eliminating voltage droop towards the end of your battery's charge cycle and ensuring consistent throttle response and flight characteristics.
• XT90 Connector — This high-quality connector is the gold standard in RC aviation, offering superior current-carrying capacity, secure engagement, and reliable contact throughout extended flying sessions without heating, arcing, or loose connections.
• Compact, Lightweight Design — Measuring just 137 x 42.5 x 26mm and weighing around 331g, this battery fits seamlessly into compact airframes and fuselage compartments where space is at a premium, making it ideal for FPV planes, wings, and other weight-conscious applications.
• Recommended 1-3C Charge Rate — The manufacturer recommends charging at conservative rates between 1C and 3C, which equates to 3.3 to 9.9 amps for this battery, ensuring maximum cycle life, thermal stability during charging, and safe operation with standard RC battery chargers.
• Soft Case Construction — The flexible protective case shields the battery cells during transport and storage whilst remaining light and packable, contrasting with rigid cases that add unnecessary weight to your aircraft.
• Simultaneous Stable Discharge Technology — Gens Ace's engineering allows these batteries to discharge stably across multiple cells simultaneously, meaning balanced cell performance and predictable power delivery throughout your flight, without the imbalance that can develop in inferior batteries.

Technical Performance

The Gens Ace G-Tech Soaring battery represents the pinnacle of modern LiPo battery engineering for RC aircraft and multi-rotor platforms. Built with premium lithium polymer cell chemistry, this 4S1P pack delivers consistent, predictable power across the entire discharge cycle, eliminating the voltage sag and performance inconsistency that plagued earlier battery generations. The 30C continuous discharge rating provides ample headroom for typical RC aircraft applications, whilst the 60C burst capability ensures you have reserve power for aggressive manoeuvres and rapid acceleration without pushing the battery into thermal distress or voltage collapse. Each cell in this four-cell series pack operates at 3.7V nominal voltage, and the pack maintains this voltage stability thanks to Gens Ace's advanced low internal resistance design, which reduces energy losses during discharge and minimises heat generation. The 331g weight is carefully engineered to provide maximum capacity without excessive mass penalty, making this battery suitable for FPV planes, fixed-wing aircraft, quadcopters, hexacopters, and specialised RC wings where weight efficiency directly impacts flight performance. The battery measures 137mm in length, 42.5mm in width, and 26mm in height, dimensioning that allows installation in moderately-sized airframe compartments without requiring extensive modification. The soft case construction uses durable, flame-retardant materials that protect cells during transport and storage. Gens Ace manufacturers this battery to ISO9001 and ISO14001 standards, ensuring consistent quality control, environmental responsibility, and safety compliance throughout the production process.

Frequently Asked Questions

• What types of RC aircraft is this battery suitable for? — The Gens Ace G-Tech Soaring battery is specifically engineered for FPV planes, fixed-wing aircraft wings, quadcopters, hexacopters, and other unmanned aerial vehicles requiring 14.8V nominal voltage and moderate to high discharge rates. The 30C continuous and 60C burst rating makes it ideal for performance-oriented applications where sustained power and dynamic responsiveness are essential.
• How long will this battery last on a single charge? — Runtime depends entirely on your aircraft's weight, motor efficiency, flying style, and throttle management. With a 3300mAh capacity and typical aircraft current draws of 20-50 amps, expect 4-15 minutes of flight time, though more efficient aircraft may achieve longer durations. Always monitor voltage during flight and land when you reach 3.0V per cell (12.0V total) to preserve battery cycle life.
• What charger do I need for this battery? — This battery requires a LiPo-compatible balance charger that supports 4S charging with XT90 connector compatibility or a suitable XT90 to charging port adapter. Recommended charge rates are 1-3C, which means charging at 3.3 to 9.9 amps. Never use a charger not specifically designed for LiPo batteries, as this creates serious fire and explosion risks. Always charge in a safe location away from flammable materials.
• Is this battery suitable for beginners? — Whilst the battery itself is reliable and well-engineered, LiPo battery operation requires responsibility and knowledge. Beginners should ensure they understand LiPo safety protocols, including proper charging procedures, voltage monitoring during flight, safe storage in fireproof containers, and proper disposal when the battery reaches end-of-life. If you're new to LiPo batteries, consider seeking advice from experienced RC operators or from the RC Model Shop team.
• What is the difference between the G-Tech Soaring and the older Soaring model? — The G-Tech designation indicates this is the current generation of the Soaring line, featuring Gens Ace's proprietary G-Tech connector technology and optimised cell chemistry. The previous version (model GEA33004S30X9) lacked the G-Tech microchip and connector improvements. The G-Tech version offers improved reliability, more sophisticated charge monitoring, and enhanced safety features.
• How should I store this battery? — Always store this battery in a cool, dry location away from direct sunlight and heat sources. Ideally, store it at approximately 50% charge (around 3.8V per cell or 15.2V total for a 4S pack). Never store fully charged or fully discharged, as this stresses the cells and reduces overall battery lifespan. Use a fireproof LiPo storage bag for additional safety. Check the battery voltage monthly during storage, and top up to 50% charge if voltage has drifted.
• Is the XT90 connector compatible with my charger? — Most modern RC battery chargers support XT90 connectors directly, but some older chargers may require an adapter cable. Check your charger's specifications before purchase. The XT90 connector is one of the most widely supported connectors in RC aviation, so compatibility is rarely an issue with contemporary equipment.
• What weight limit can this battery support? — There is no absolute weight limit for the aircraft itself, but battery performance depends on the power-to-weight ratio and current draw. Heavier aircraft will draw more current, reducing flight time proportionally. As a general rule, aircraft weighing 2-4kg can comfortably use this battery with sensible flying; lighter aircraft will achieve significantly longer flight times.
