Technical Performance

The Overlander Sport 11.1V 2200 mAh 35C LiPo Battery represents the pinnacle of compact power delivery for RC aircraft and lightweight aerobatic models. Built using premium Fullymax lithium polymer cells and assembled through the superior stacking method, this battery delivers exceptional consistency and reliability that distinguishes it from lesser-quality alternatives. The three-cell (3S) lithium polymer configuration provides 11.1V nominal voltage — a voltage that perfectly suits the ESCs and brushless motors commonly found in modern sport planes, FPV drones and small warbirds available to RC enthusiasts in the UK and worldwide.

Performance metrics tell the complete story: with a maximum continuous discharge current of 77A and an explosive burst capacity of 143A, this battery can power demanding applications that require instantaneous power response. The 35C continuous rating ensures stable voltage delivery during sustained manoeuvres, whilst the 65C burst rating activates during those critical moments when you need every ounce of available energy. For sport planes, this means crisp, responsive elevator control and rapid rolls. For FPV drones, it translates into aggressive acceleration and precise acrobatic capability. For aerobatic models, it delivers the sustained power needed for complex 3D manoeuvres.

The construction quality reflects Overlander's partnership with Fullymax and commitment to precision engineering. Every cell is individually matched before assembly, with internal resistance, voltage and weight balanced across all cells to prevent performance degradation and ensure uniform charge acceptance during the charging cycle. The ultrasonic welding process used to create internal connections exceeds the quality standards of many competing brands, whilst the JST-XH balance connector enables proper cell-by-cell charging management when used with any compatible LiPo balance charger. The 14AWG silicone-insulated power leads are rated for the full 143A burst current specification, ensuring no bottleneck exists between battery and model.

Frequently Asked Questions

• Is the Overlander 11.1V 2200mAh 35C LiPo suitable for beginners in RC flying? — Yes, this battery is suitable for beginners flying appropriate RC aircraft. However, beginners must understand LiPo safety requirements before use. You'll need a proper LiPo balance charger, and you must never leave the battery unattended whilst charging. Always follow the manufacturer's instructions for safe charging, discharging and storage. The 11.1V (3S) configuration is beginner-friendly compared to higher-voltage packs, and the 2200mAh capacity provides good flight times without excessive weight.
• What charger do I need for this Overlander LiPo battery? — You need a dedicated LiPo balance charger or a multi-chemistry charger with LiPo mode enabled. The JST-XH balance connector must be connected during charging to ensure each of the three cells charges evenly. The battery should be charged at a C-rate no higher than 1C (which would be 2.2A maximum for this pack), though charging at 0.5C (1.1A) is generally safer for battery longevity. Never use a regular NiMH or NiCd charger, as this will damage the battery and create serious safety hazards.
• What is the C rating and why does it matter on this battery? — The C rating indicates how quickly the battery can discharge its energy relative to its capacity. This 35C battery can discharge at 35 times its capacity (35 × 2200mAh = 77A continuous). This means the battery won't overheat or voltage sag dramatically during high-demand operations. The 65C burst rating means it can handle 143A for short periods during intense manoeuvres. A higher C rating is essential for racing drones, 3D planes and high-performance models that demand instant power response.
• How long will this battery last in terms of flight time? — Flight time depends entirely on your model's motor, ESC and weight. Generally, a 2200mAh battery in a lightweight aerobatic plane might provide 8-12 minutes of flight at normal throttle, whilst in a heavier sport plane you might see 6-10 minutes. In FPV drones, expect 6-9 minutes depending on flight style and conditions. The only way to know precisely is to test with your specific model and flight style.
• What should I do to store this LiPo battery safely? — Store the battery at approximately 50% charge (around 3.85V per cell, or 11.55V total for a 3S pack). Keep it in a cool, dry location away from direct sunlight and heat sources — never in a hot car or near windows. Check on it every couple of months and give it a quick top-up or discharge to maintain that 50% storage voltage. Always use a LiPo safety charge sack for storage in case of any cell failure. Never store a fully charged or completely drained battery.
• What is the difference between this Overlander and other 3S LiPo batteries available in the UK? — The Overlander Supersport Pro range stands out because every cell is individually matched for internal resistance, voltage and weight before assembly, and the batteries are assembled using the superior stacking method rather than simpler construction techniques. The premium Fullymax cells are manufactured in a fully automatic, dust-free facility with rigorous quality control. Gold-plated connectors, multi-strand silicone leads and ultrasonic welding ensure durability and efficient power transfer. Whilst other 3S packs may offer similar voltage and capacity, Overlander's manufacturing precision translates into better consistency, longer lifespan and more reliable performance in competitive and recreational flying.
• Can I use this battery with any RC aircraft? — No. You must verify that your aircraft's ESC and motor are rated for 11.1V (3S LiPo) power. Many older RC models, beginner aircraft and small trainer planes use 2S batteries instead. Using the wrong voltage can damage your electronics or cause poor performance. Always consult your model's manual before purchasing a battery. If your manual specifies 2S or 4S only, this 3S pack will not be suitable.
• What is the maximum current this battery can handle safely? — The maximum continuous discharge current is 77A (35C × 2200mAh), and the maximum burst current is 143A (65C × 2200mAh). Your ESC and motor must be rated to handle these currents, or the battery will be limited by your equipment rather than delivering its full potential.
