The Pro-Range 11.1V 3300mAh 35C 3S Lithium Polymer Battery Pack is a high-capacity, high-discharge energy storage system engineered for demanding radio-controlled (RC) models, large drones, and industrial robotics. The “3S” architecture means it contains three premium lithium-polymer pouch cells wired in series to supply a steady nominal 11.1V. Delivering a robust 4200mAh capacity coupled with a 35C continuous discharge rate, this pack provides both long-lasting runtimes and the raw current burst capability needed to keep high-torque brushless motors from stalling under extreme loads.
