HobbyKing has pushed the boundaries of RC power—from the legendary Blue series to the durable, low-IR of Graphene, and the relentless, hard-hitting delivery of the Rapid. Now, it’s time to ascend to the absolute peak of RC performance. Welcome to APEX. Engineered specifically for the brutal demands of modern FPV drone racing, freestyle, and high-speed RC flight, the APEX series introduces a boxy, near-square cell architecture. Designed to sit perfectly under FPV frames or aircraft fuselages, APEX optimizes your center of gravity while maximizing power density. At the heart of APEX is a pure Cobalt formulation paired with Z-Fold structure. This eliminates the internal resistance bottlenecks found in traditional rolled cells, delivering 180C discharge rate. The APEX maintain rock-solid voltage stability when you punch the throttle hard. Available in versatile capacities from 1100mAh to 4000mAh and configurations spanning 4S to 8S, APEX is the definitive power source for pilots who refuse to compromise. Learn More
