High-Performance Power Solution for Professional RC Models The OVONIC 4S Lipo Battery (14.8V, 8000mAh, 120C) with EC5 Connector is tailored for RC hobbyists seeking reliable, high-power energy for their equipment. It delivers robust performance to handle demanding scenarios—from high-speed RC truck racing and FPV drone flights to large-scale RC boat and airplane operations—making it an ideal choice for both casual enthusiasts and professional users. Core Specifications for Reliable Performance Power & Capacity: Features a 14.8V rated voltage (4S1P cell configuration), an 8000mAh large capacity, and a 120C continuous discharge rate. This powerful combination ensures sufficient energy to drive high-load RC models, such as Pro Trucks, RC Jets, Bashers, and FPV racing drones, extending running time by 12% compared to standard batteries of the same category. EC5 Connector Compatibility: Equipped with a standard EC5 Plug—no extra adapters needed. It seamlessly matches the power interfaces of most professional RC vehicles (cars, trucks, boats) and aircraft (drones, airplanes, helicopters), enabling plug-and-play convenience and saving time on interface modifications. Optimized Size & Weight: Measures 140×49×49mm (5.5×2×2 inches, L×W×H, ±3mm tolerance) and weighs approximately 630g (1.3lb, ±5g tolerance). Its compact, balanced design fits into the battery compartments of most mid-to-large-scale RC models, while the 5% lighter weight (compared to same-capacity ordinary batteries) reduces unnecessary load, ensuring optimal maneuverability and preventing performance loss. Premium Quality & Long-Lasting Durability Safety Certified: Complies with ISO international quality standards, meeting strict safety regulations to minimize risks during use. Constructed with high-grade lithium cobalt oxide (LiCoO2) cells, it reduces the chances of overheating, leakage, or swelling, providing a secure power source for your valuable RC gear. Extended Cycle Life: Boasts an impressive cycle life of up to 450 times—significantly higher than the industry average for high-capacity 4S Lipo batteries. It maintains stable capacity and discharge efficiency even after repeated charging and use, offering long-term value and reducing the need for frequent battery replacements. Efficient Energy Management: With 4% lower internal resistance than ordinary 4S Lipo batteries, it minimizes power loss during discharge, ensuring maximum energy is delivered to your RC model. Additionally, it supports 6% faster charging (when used with recommended chargers), cutting down waiting time and getting you back to your RC hobby quicker. Wide Compatibility with RC Equipment This battery is designed to work with a diverse range of high-performance RC models, including: RC Ground Vehicles: Pro Trucks, Bashers, large-scale RC cars, off-road trucks, and racing trucks that require a 14.8V power system. RC Watercraft: RC Jets, large racing boats, and high-speed watercraft optimized for high-capacity, high-voltage batteries. RC Aircraft: FPV racing drones, large RC airplanes, helicopters, quadcopters, and fixed-wing models that demand reliable, high-power energy. Other RC Hobby Models: Various professional-grade RC hobby equipment and custom-built models compatible with 4S Lipo batteries.
