Efficiency and compact design for demanding RC systems The Extralink battery is an advanced energy source, designed for users who value dynamics and reliability. While maintaining compact dimensions (75 mm x 30 mm x 4.8 mm), the battery offers a voltage of 11.1 V and a capacity of 850 mAh. The key parameter is an extremely high discharge rate of 100C, which guarantees instantaneous power supply at times of peak demand. A safe and stable connection is provided by the popular XT30 connector. Universal compatibility with a wide range of models The universal nature of the battery makes it an ideal choice for enthusiasts of various fields of modeling. The device provides stable power for many types of machines, including: FPV drones - ideal for dynamic flights. RC cars – to provide high torque. RC helicopters – guaranteeing control precision. RC boats and planes – offering long-lasting power. Advanced LiPo technology for maximum efficiency The use of modern lithium-polymer cells (LiPo) allows you to achieve parameters unavailable for traditional batteries. This technology offers higher capacity and efficiency while maintaining low weight. The most important advantages include: High voltage per cell - which translates into greater engine power. Ability to discharge quickly - essential in professional RC models. Longevity – optimized cell chemistry extends service life. Use in high-power systems - dedicated to the most demanding structures. The perfect choice for top FPV designs. The 850 mAh battery has been optimized in terms of weight and performance, making it a recommended choice for many popular FPV drones available on the market. Works perfectly with models such as: Chimera5 BetaFPV Pavo Pico iFlight Alpha A85 HGLRC Rekon 3 GEPRC MARK5 / MARK4 Extreme discharge coefficient of 100C Thanks to the discharge coefficient of 100C, the battery provides a huge reserve of power, which is crucial during aggressive maneuvers and racing flights. This allows you to achieve the highest speed and immediate response of the engines to the movements of the control sticks. This is an uncompromising solution for any FPV model, boat or car, where every millisecond of acceleration counts. A clear advantage over Li-ion technology. Choosing an Extralink LiPo battery is an investment in better performance and safety. Compared to standard Li-ion cells, this product is distinguished by: Excellent efficiency - stable parameters even under heavy load. Higher level of safety - lower risk of overheating and failure during intensive work. Longer service life - the graphs confirm a much slower degradation of capacity with the number of charging cycles.
