RC enthusiasts in the UK consistently choose Gens Ace batteries for their reliability, consistent quality and excellent value, and this model exemplifies why the brand is trusted by hobbyists and competitors alike.

Key Features

• High Discharge Rating (80C) — The 80C continuous discharge rate means this battery can safely deliver up to 408 amps of current (5100mAh × 80C = 408A), providing the explosive power needed for aggressive flight manoeuvres, high-speed acceleration and demanding motor performance without voltage sag or thermal stress.
• 6S Lithium Polymer Chemistry (22.2V) — Six cells in series deliver 22.2 volts nominal voltage, which is the industry standard for high-performance electric aircraft and motor gliders, ensuring compatibility with most modern brushless RC flight motors and ESCs designed for 6S applications.
• 5100mAh Capacity — This 5100 milliamp-hour capacity provides extended flight time and sufficient energy reserves for extended sessions, making it perfect for F5B motor gliders and other aircraft where longer endurance is desired without excessive weight penalty.
• No Connector Included — The battery ships without a pre-installed connector, giving you complete freedom to solder the specific plug type that matches your RC aircraft's power distribution system, whether that's an XT90, XT60, or any other connector standard you prefer.
• Soft Case Construction — The flexible soft case design keeps weight to a minimum whilst still providing protection during storage and transport, and the compact form factor makes it easier to fit into fuselages and battery compartments of various aircraft designs.
• Gens Ace Heritage — Backed by a company with two decades of dedicated research and manufacturing experience in NiMH, Li-Po and Li-Fe battery technology, you're investing in a brand that understands RC power delivery at the deepest technical level.
• Consistent Quality — Gens Ace's reputation for reliable, consistent battery performance means each cell is matched and tested, reducing the risk of imbalanced charging, premature failures or unpredictable power delivery during critical flights.
• Practical Dimensions — At 155mm long, 43mm wide and 58mm tall, this battery is compact enough to fit into reasonably tight spaces whilst remaining robust enough to handle the demands of serious flying without damage.

Technical Performance

The GENSACE Li-Po Sport 6S 22.2V 5100mAh 80C battery represents a carefully engineered compromise between capacity, weight and discharge capability for RC flight applications. The 6S (six-cell) lithium polymer configuration delivers 22.2 volts nominal voltage, which is the standard power level for high-performance brushless motor systems used in contemporary RC aircraft, particularly F5B motor gliders where efficiency and sustained power delivery are paramount. With an 80C discharge rating, this battery can safely supply continuous current up to 408 amps, though realistic flight applications will typically draw between 80-150 amps depending on motor KV rating, propeller configuration and flight style. The 5100mAh capacity strikes an excellent balance: it's substantial enough to provide meaningful flight duration on demanding applications, yet light enough (783 grams) to integrate without excessive weight penalty that would compromise climb performance or handling characteristics. The soft case design minimises unnecessary weight whilst still protecting the cells and solder tabs from mechanical damage during handling and storage. For demanding electric flight where power-to-weight ratio matters enormously, this battery's engineering focus on high discharge capability combined with moderate capacity makes it particularly suited to aerobatic flying, motor glider sustaining flights and any application where peak power matters as much as endurance. The absence of a pre-fitted connector is actually a feature for experienced builders, as it allows custom soldering of whichever connector type matches your existing infrastructure—whether that's XT90, XT60, or specialist aviation connectors.

Frequently Asked Questions

• Is the GENSACE 6S 5100mAh 80C battery suitable for F5B motor glider flying? — Yes, this battery is specifically designed and recommended by the manufacturer for F5B motor glider applications. The 6S voltage is standard for modern brushless motor glider systems, and the 80C discharge capability provides the high current needed for sustained climbs and sustained flights. The 5100mAh capacity offers good flight duration without excessive weight.
• What does the 80C discharge rating actually mean for my flying? — The 80C rating means this battery can continuously discharge at 80 times its capacity in amps. So 5100mAh (5.1Ah) × 80C = 408 amps maximum continuous discharge. In practical terms, this means you can safely pull high current without the battery overheating or experiencing dangerous voltage sag, which is essential for aggressive flying, rapid climbs and demanding manoeuvres.
• Why does this battery come with no connector? — Gens Ace supplies this battery without a connector because experienced RC builders and pilots prefer to choose their own connector type based on their existing equipment. This saves money and eliminates the need to cut off an unwanted connector. You simply solder the connector of your choice directly to the power tabs.
• How heavy is this battery and will it fit in my aircraft? — The battery weighs 783 grams and measures 155mm (length) × 43mm (width) × 58mm (height). Whether it fits your aircraft depends on your specific airframe design and battery compartment dimensions. The soft case design keeps weight minimal, making this one of the lighter options for its capacity and discharge rating. Compare these dimensions against your fuselage battery bay before purchasing.
• Is this battery suitable for beginners? — This is not a beginner-oriented product. It's designed for experienced RC pilots flying demanding aircraft like F5B motor gliders. If you're new to RC flight, you'll want to start with a simpler, pre-assembled battery system and gain experience with charging and handling before progressing to no-connector batteries that require soldering.
• What charger should I use with the GENSACE 6S 5100mAh battery? — You need a charger specifically capable of charging 6S LiPo batteries. Look for chargers with 6S balance charging capability, and ensure the maximum charge current supports safe charging rates (typically 1-2C, which would be 5.1-10.2 amps for this 5100mAh pack). Popular options include iSDT, SkyRC and Hobbywing chargers, all available at UK RC retailers.
• How does the GENSACE 6S compare to other high-performance LiPo batteries? — The GENSACE Li-Po Sport line is recognised for consistent quality and reliable performance at competitive pricing. The 80C discharge rating puts it in the high-performance category alongside brands like Turnigy, Horizon and other established manufacturers. The main difference is the balance between capacity (5100mAh is moderate-to-high), voltage (6S is standard for aircraft), and discharge rate (80C is excellent). Other packs might offer higher capacity or slightly higher discharge ratings, but this particular configuration is optimised specifically for demanding flight applications where balanced performance matters most.
• Can I use this battery in other RC models besides F5B motor gliders? — Yes, any RC model with a 6S-compatible brushless system can use this battery. However, it's important to check your ESC rating and motor specifications to ensure they're designed for 22.2V (6S) operation. The 5100mAh capacity and 80C rating make it suitable for high-performance aircraft, but it may be over-specified (and unnecessarily expensive) for slower, less demanding models.
• How long will this battery last between charges during flying? — Flight time depends on your motor KV, propeller size, flying style and average current draw. Typically, a 5100mAh pack on an F5B motor glider might provide 15-40 minutes of flight depending on these factors. The beauty of a motor glider is that with thermals and slope lift, you can significantly extend flight time beyond pure motor endurance.
