This particular Sport series battery combines practical specifications with affordability, making it accessible to enthusiasts building or upgrading their F3K and DLG (Dynamic Launch Glider) hand-launch glider setups.

Whether you are a seasoned RC enthusiast in the UK or just beginning to explore the world of lightweight RC flying, this battery offers the performance and reliability you need. The JR connector included as standard ensures compatibility with a wide range of receiver systems commonly used in the hand-launch glider community. The 40C discharge rating provides sufficient punch for the acceleration demands of hand-launched models whilst maintaining a safe operating envelope.

Key Features

• Ultra-Lightweight Design — Weighing just 15 grams, this battery minimises weight penalty on your RC glider, directly improving climb rate, thermal soaring efficiency, and overall flight duration. Every gram saved translates to better performance in competitive or recreational flying.
• Compact Dimensions — The slim 57 x 18 x 7mm profile fits easily into tight battery bays found in modern hand-launch glider designs, without requiring extensive fuselage modifications or weight-adding structural reinforcements.
• 40C Discharge Rating — This continuous discharge capability ensures the battery can handle the current demands of electric motors in hand-launch gliders during climb-out and sustained powered flight, delivering responsive acceleration when you need it most.
• 3.7V Single Cell Chemistry — The 1S configuration operates at the standard single-cell lithium polymer voltage, providing excellent compatibility with the vast majority of F3K and DLG receiver systems and motor setups already in use across UK clubs and flying sites.
• 480mAh Capacity — This capacity strikes an ideal balance between flight duration and weight, allowing sufficient energy for multiple hand launches and powered climbs without the mass penalty of larger capacity cells that would compromise the model's performance characteristics.
• JR Connector Standard — The included JR connector is a widely-used standard in RC aviation, particularly in the hand-launch glider community, ensuring straightforward installation with compatible receivers without requiring adapter leads or soldering.
• Soft Case Construction — The flexible soft case design contributes to the overall lightness of the battery whilst providing essential protection against physical damage, short circuits, and impact during storage and transport to flying sites.
• Gens Ace Quality Assurance — Backed by twenty years of battery engineering expertise and quality control protocols developed by professional engineers, this battery meets rigorous safety and performance standards expected of genuine Gens Ace products.

Technical Performance

The Gens Ace Li-Po Sport 480mAh 40C battery delivers measured and reliable performance engineered specifically for the unique demands of hand-launched RC gliders used throughout the UK. The 1S1P configuration ensures straightforward integration with standard receiver systems; the single 3.7-volt lithium polymer cell operates within safe parameters that protect both the battery itself and connected electronics from overvoltage conditions. At 480mAh capacity, the battery stores sufficient energy for extended flight sessions featuring multiple thermal climbs and powered ascents typical of modern F3K competition or recreational DLG flying. The 40C continuous discharge rating indicates the battery can safely provide 19.2 amperes of current (40 × 0.48Ah), which aligns perfectly with the modest power requirements of brushed or small brushless motors commonly found in hand-launch glider applications. The 15-gram weight distribution, when combined with the compact 57 × 18 × 7mm dimensional profile, ensures minimal impact on the model's centre of gravity and rotational inertia, both critical factors in achieving optimal flight characteristics. The soft case construction employs materials selected to withstand the rigours of fielded use—protection against mechanical damage, vibration-induced wear, and the occasional heavy landing in grass or soft terrain. Gens Ace's manufacturing processes incorporate quality control measures developed through two decades of battery technology advancement, ensuring consistent cell matching, connector assembly standards, and safety device integrity across every unit produced. The JR connector selected for this battery remains a respected standard in the RC aviation community, offering secure connections that resist accidental disconnection during powered manoeuvres whilst remaining easy to disconnect for charging and inspection.

Frequently Asked Questions

• Is the Gens Ace 480mAh 40C 1S battery suitable for F3K and DLG hand-launch gliders? — Yes, this battery is specifically recommended for F3K and DLG hand-launch glider applications. The 480mAh capacity and 40C discharge rating match the modest power demands of electric motors in these models, whilst the 15-gram weight ensures minimal performance penalty on lightweight airframes common in this category.
• What does the 40C discharge rating mean for my RC glider? — The 40C rating indicates the battery can continuously discharge at 40 times its capacity in amperes. For this 480mAh cell, this means it can safely provide 19.2 amps continuously without damage. This rating is sufficient for hand-launch glider motors which typically draw between 5 and 15 amps during climb-out.
• Can I use this battery with my existing DLG receiver if it has a JR connector? — Yes, the JR connector included on this battery is a standard connection used across much of the RC aviation community. Provided your receiver features a matching JR port, installation is straightforward and requires no adapters or modifications.
• How does the 57 × 18 × 7mm size compare to other 1S batteries for RC gliders? — This compact profile is typical for lightweight hand-launch glider batteries and represents an excellent balance between capacity and physical footprint. The slim dimensions allow installation in fuselage battery bays without requiring enlargement or structural modification to your model.
• Is 480mAh capacity enough for a full flying session with my F3K glider? — The 480mAh capacity typically supports multiple hand launches and powered climbs in a single session. Flight duration between charges depends on motor efficiency, flying style, and thermal activity at your site. Many pilots carry multiple batteries to ensure extended flying without downtime waiting for recharges.
• What charger do I need for this 1S battery? — You will need a lithium polymer battery charger capable of charging 1S packs. Many modern RC battery chargers, including balancing chargers and dedicated LiPo chargers available in the UK, support 1S charging. Follow the charger manufacturer's instructions and always use appropriate charging leads compatible with your JR connector.
• Is this battery waterproof for flying in wet conditions? — Whilst the soft case provides protection against minor moisture and splash, lithium polymer batteries should be kept dry whenever possible. Exposure to heavy rain or water immersion may damage internal cells and create safety hazards. Store and operate this battery in dry conditions.
• What makes Gens Ace batteries different from other budget options? — Gens Ace brings twenty years of battery engineering expertise, quality control protocols, and the backing of 200 professional engineers and technicians to every product. This investment in research and manufacturing discipline translates to consistent cell performance, reliable connectors, and safety features that distinguish genuine Gens Ace batteries from lower-quality alternatives.
