Product overview

High Discharge/High Power 18.5V 5S 5000mAh Li-Po Battery for Rescue-Hero Coast Guard Search & Rescue Heli, Teleoperated Robot, FPV Drone | Battery Manufacturers in China & Battery Supply Factory

High Discharge / High Power 18.5V 5S 5000mAh Li-Po Battery is a type of lithium polymer battery in 5S series, featuring 18.5V nominal voltage and 5000mAh capacity. It is engineered for mission-critical RC and robotic systems that require high output power, long endurance, and stable voltage during continuous operation.

Composed of superior raw materials, lithium cobalt and soft aluminum film, the 18.5V 5S 5000mAh battery is lightweight, compact, and designed with high energy density. The advanced pouch structure ensures efficient heat dissipation and mechanical flexibility, supporting reliable performance in demanding rescue and aerial environments.

Featuring low internal resistance and 20C–120C high burst current, the 18.5V 5S 5000mAh Li-Po battery can discharge maximum power instantaneously without rapid temperature increase. This enables strong lift, fast acceleration, and responsive control for emergency maneuvers and high-load tasks. To ensure ultimate safety, its internal is integrated with a protection circuit board (battery PCB) to protect against overcharge, overdischarge, overcurrent, over-temperature, and short circuit with 1–3ms fast response. The whole Li-Po battery production process conducts in high-automation production lines and medical-grade dust-free workshops under strict humidity control, supported by an MES system. It always delivers stable energy output and steady voltage to power rescue helicopters, teleoperated robots, FPV drones, and other high-reliability unmanned systems.
