At RC Model Shop, we stock genuine FMS batteries because we understand that battery quality directly impacts flight safety, aircraft longevity and your overall RC flying experience. Counterfeit or low-quality batteries pose genuine risks to both your model and your safety. Our commitment to stocking only authorised, genuine products means you can purchase this FMS Lipo Battery with complete confidence, knowing you're getting authentic FMS engineering and quality assurance.

Key Features

• 11.1V Three-Cell Configuration — This battery delivers 11.1 volts across three lithium polymer cells, which is the optimal voltage for the FMS 1.1 Cub and similar electric RC aircraft models, ensuring your plane performs exactly as the manufacturer intended without voltage-related performance issues.
• 1300mAh Capacity — The 1300 milliamp-hour capacity provides practical flight times of 8-12 minutes depending on flying style and throttle usage, allowing you to complete multiple flights during a single session at your local RC airfield or club.
• 20C Continuous Discharge Rate — The 20C rating means this battery can safely deliver 26 amps of continuous current (1300mAh × 20C = 26A), providing the instant power needed for normal aerobatic flight, climbs and sustained acceleration without voltage sag or performance loss.
• Genuine FMS Manufacturing — This is an authentic FMS battery, not a counterfeit or third-party alternative, guaranteeing you receive the quality control, performance consistency and safety standards that FMS batteries are known for throughout the world.
• Purpose-Built for 1.1 Cub — Designed and optimised specifically for the FMS 1.1 Cub trainer aircraft, this battery integrates perfectly with the aircraft's power management systems, weight distribution and performance envelope for balanced, reliable flight characteristics.
• Compact and Lightweight Design — The battery's compact form factor minimises weight whilst maximising capacity, helping keep your RC aircraft within optimal centre of gravity limits and improving flight duration through reduced parasitic weight.
• Extended Flight Session Capability — Purchase multiple FMS batteries to enable back-to-back flights without the downtime required to charge and cool a single battery between flights, maximising your time in the air at the flying field.

Technical Performance

The FMS Lipo Battery 1300mAh 11.1V 20C represents several decades of lithium polymer battery development refined specifically for electric RC aircraft applications. The three-cell (3S) LiPo chemistry delivers the voltage curve that electric motors in RC planes are engineered around, providing consistent throttle response and power delivery from full charge down to the point where the battery requires recharging. The 20C continuous discharge capability translates to genuine engineering margins for sustained flight, meaning your aircraft experiences stable voltage even during demanding manoeuvres such as loops, rolls, vertical climbs or sustained high-throttle flight. The 1300mAh capacity represents the optimised balance for trainer and sport aircraft—sufficient for meaningful flight times whilst remaining light enough that the battery contributes positively to your aircraft's flight characteristics rather than adding excessive dead weight. FMS batteries undergo rigorous quality control at manufacture, with each cell matched for voltage consistency and each pack tested for internal resistance and capacity before shipping to customers. The battery's construction using premium lithium polymer chemistry ensures consistent performance across hundreds of charge and discharge cycles when properly maintained, making this an investment in long-term reliability rather than a disposable component. Proper storage, charging and handling of LiPo batteries is essential for safety and longevity—we recommend using a dedicated LiPo charger with balancing capability and storing the battery at approximately 50% charge when not in use for extended periods.

Frequently Asked Questions

• Is this battery compatible with my RC aircraft? — This battery is designed specifically for the FMS 1.1 Cub trainer aircraft. It may be compatible with other electric RC planes that specify 11.1V three-cell LiPo batteries with similar capacity and discharge ratings, but we recommend checking your aircraft's documentation before purchasing. Contact our team at RC Model Shop if you're unsure about compatibility with your specific model.
• How long will this battery power my FMS 1.1 Cub? — Flight time typically ranges from 8 to 12 minutes depending on your flying style, throttle usage, air temperature, and aircraft condition. Sport flying with frequent climbs and manoeuvres will consume the battery faster than gentle, level flight. Many RC pilots purchase multiple batteries to enjoy consecutive flights without waiting for battery cool-down and recharge periods.
• What is the 20C rating and why does it matter? — The 20C rating indicates the maximum continuous current the battery can safely deliver. Multiplying 1300mAh by 20C gives a maximum continuous current of 26 amps. This rating ensures your aircraft's electric motor receives instant, stable power without voltage sag during demanding flight phases, resulting in predictable handling and consistent aerobatic performance.
• How should I store and care for this LiPo battery? — Store the battery at approximately 50% charge in a cool, dry location away from metal objects and extreme temperatures. Use only a charger specifically designed for lithium polymer batteries with integrated cell balancing—never use standard NiMH chargers. Always inspect the battery for physical damage, swelling or unusual odours before each use, and replace any battery that shows signs of damage or degradation.
• Can I use this battery with other FMS aircraft models? — This battery is optimised for the FMS 1.1 Cub, but may be compatible with other FMS aircraft or compatible RC planes designed for 11.1V three-cell LiPo batteries of similar capacity. Check your aircraft's battery bay dimensions and power requirements before purchasing, as some aircraft models require different battery capacities for optimal weight distribution and balance.
• What charger do I need for this battery? — You'll need a charger specifically designed for lithium polymer (LiPo) batteries with integrated cell balancing. Many RC enthusiasts use multi-chemistry chargers from brands like Spektrum, Hobbywing or similar manufacturers. Avoid cheap or generic chargers that lack proper LiPo protection circuitry, as they pose genuine safety risks.
• Why is this FMS battery better than cheaper alternatives? — Genuine FMS batteries undergo rigorous quality control at manufacture, with each cell matched for consistent performance. Counterfeit or low-quality alternatives often use substandard cell chemistry with poor internal consistency, resulting in voltage imbalance, rapid capacity loss, and safety risks including swelling or fire during charging. Investing in a genuine FMS battery ensures your aircraft performs safely and reliably for hundreds of flight cycles.
