Technical Performance

The Overlander 2200mAh 11.1V 3S 35C Supersport Pro LiPo Battery represents the pinnacle of compact battery engineering for demanding RC applications. Built upon a foundation of high-grade Fullymax cells, this battery delivers consistent, predictable performance that discerning RC enthusiasts expect. The 35C continuous discharge rate combined with the 65C burst capability creates a flexible power delivery profile capable of handling the variable current demands of modern RC motors and speed controllers. The maximum constant current output of approximately 77 amperes provides sufficient power for small to medium RC aircraft and drones, whilst the burst capacity of 143 amperes ensures explosive acceleration and responsive performance when you need it most. The 24.42 watt-hour capacity places this battery in the sweet spot for extended flight times without excessive weight penalties, particularly important for aircraft where every gram impacts flight duration and handling characteristics. The precision matching of internal cell resistance, voltage and weight ensures that all three cells deliver power equally and consistently, eliminating the voltage imbalances that can lead to premature cell failure or reduced performance. The ultrasonic welding technique used in battery assembly creates permanent, high-integrity connections between cells that resist degradation and maintain electrical efficiency throughout hundreds of charge cycles. The 14AWG (2.5mm) wire gauge has been carefully selected to support the high current demands whilst minimising resistive heating during peak power draws. For RC cars and vehicles requiring rapid acceleration and sustained high-speed running, this battery's characteristics suit competitive racing environments where reliability and consistent power output are non-negotiable. For RC aeroplane and drone pilots, the compact dimensions and lightweight construction preserve the centre of gravity and response characteristics essential for aerobatic performance, racing drones, and FPV operations.

Frequently Asked Questions

• What is the difference between the 35C continuous rating and the 65C burst rating? — The 35C rating represents the maximum constant current the battery can safely discharge continuously without damage, delivering approximately 77 amperes at full capacity. The 65C burst rating is a temporary boost capability, lasting only a few seconds, that allows the battery to deliver up to 143 amperes during peak power demands such as rapid acceleration, tight cornering, or aggressive aerobatic manoeuvres. Think of continuous discharge as your battery's sustained performance capability, whilst burst is the turbo mode it activates for brief periods when you really need maximum power.
• Why do LiPo batteries require a special charger? — Lithium Polymer batteries have unique chemical properties that demand precise voltage control during charging. A standard charger cannot provide the balance charging functionality needed to keep all three cells at equal voltage levels. LiPo chargers specifically monitor and adjust charge current to each cell independently, preventing overcharging, cell imbalance, and the serious safety hazards including overheating or fire risk that come from incorrect charging. Always use a dedicated LiPo balance charger with the correct 3S LiPo settings.
• How long will this battery last between charges? — Runtime depends entirely on your model's motor power consumption, which varies dramatically between RC cars, drones, planes, and helicopters. A light FPV drone might fly for 8-12 minutes, whilst a small aerobatic plane could achieve 15-20 minutes of flight time. RC cars typically achieve 15-25 minutes of driving depending on speed and throttle usage. The 2200mAh capacity provides a good balance between reasonable flight/drive times and manageable weight for compact models.
• Is this battery suitable for beginners? — The Overlander 2567 is an excellent choice for experienced RC enthusiasts with established knowledge of LiPo battery safety, charging procedures, and storage requirements. Beginners new to LiPo batteries should first understand proper charging safety, the risks of overcharging and over-discharging, and the importance of supervision during charging. If you're new to LiPo batteries, we recommend investing in comprehensive educational resources about battery safety before operating this pack, and always follow the manufacturer's safety guidelines meticulously.
• What models is this battery compatible with? — This battery is designed for compact RC models specified for 11.1V (3S) operation, including FPV drones, racing drones, small warbirds, sport planes, lightweight aerobatic aircraft, and medium helicopters. The compact dimensions and 169-gram weight make it ideal for models where space is limited. Always verify that your specific model's documentation recommends 3S LiPo batteries before installation — using the wrong voltage can damage your model's electronics irreparably.
• How should I store this battery when not in use? — For long-term storage, maintain the battery at approximately 50% charge (around 3.7-3.85 volts per cell) in a cool, dry location away from direct sunlight and heat sources. Never store the battery fully charged or completely discharged, as either extreme stresses the cells and reduces lifespan. If you're storing the battery for more than a few weeks, check its voltage every couple of months and perform a brief top-up or discharge to return it to the 50% storage level, keeping the pack ready for immediate use.
• What precautions should I take to keep this battery safe? — Always charge under direct supervision in a well-ventilated area, never leaving the battery unattended whilst charging. Store in a fireproof LiPo safety sack, particularly during charging and transport. Never allow the battery to be fully discharged below 3.0 volts per cell, as this causes permanent damage. Monitor voltage and temperature during use, and stop operating immediately if the battery becomes hot or swells. Dispose of damaged or failed batteries responsibly according to local regulations, never in household waste.
• Why does internal cell matching matter? — When the three cells in this battery are matched for internal resistance, voltage, and weight, they charge and discharge equally, preventing the voltage imbalances that cause premature failure. Unmatched cells can lead to one cell being overcharged whilst others remain undercharged, creating safety risks and dramatically reducing battery lifespan. Overlander's precision matching ensures all three cells work in harmony, delivering consistent power output and maximising the number of reliable charge cycles you'll achieve.
• Can I use this battery in multiple RC models? — Yes, the Deans connector allows easy swapping between compatible models, making this battery versatile across your RC fleet. However, ensure every model you use it in is specified for 11.1V (3S) operation and has sufficient physical space to accommodate the 101 × 33 × 23mm dimensions. Always verify compatibility before installation to avoid damaging your equipment.
• What is the advantage of the Deans connector included with this model? — The Deans T-Plug connector is the industry standard for RC batteries in the UK and internationally, offering reliable secure connections with minimal electrical resistance. This widespread compatibility means this battery will connect directly to most modern RC speed controllers without adapter cables, ensuring clean power transfer and compatibility with popular models across racing, flying, and driving disciplines.
