Product overview

High Discharge/High Power 18.5V 5S 4200mAh Li-Po Battery for RC Racing Boat, Drift Car, Rock Crawler toy | Battery Manufacturers in China & Battery Supply Factory

High Discharge / High Power 18.5V 4200mAh 5S LiPo Battery is a type of lithium polymer battery in 5S series, featuring 18.5V nominal voltage and 4200mAh capacity. It is purpose-built for high-demand RC platforms that require powerful output, voltage stability, and reliable endurance during continuous high-load operation.

Composed of superior raw materials, lithium cobalt and soft aluminum film, the 18.5V 5S 4200mAh battery is lightweight, compact, and engineered for high energy density. The advanced pouch cell structure improves heat dissipation and structural integrity, making it suitable for both airborne and ground-based RC applications.

Featuring low internal resistance and 20C–120C high burst current, the 18.5V 4200mAh LiPo battery can discharge maximum power instantaneously without rapid temperature increase. This ensures aggressive throttle response, strong lift performance, and consistent power delivery during high-speed maneuvers. 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 LiPo battery production process conducts in high-automation production lines and medical-grade dust-free workshops with strict humidity control, supported by an MES system. It always delivers stable energy output and steady voltage to power XLPower Specter 700 helicopters, Swift-Blade indoor nano helicopters, RC cars, and other high-performance RC models.
