Product overview

High Discharge/High Power 18.5V 5S 2100mAh Li-Po Battery for RC Racing Boat, Drift Car, Rock Crawler toy | Battery Manufacturers in China & Battery Supply Factory

18.5V 5S 2100mAh High-Discharge & High-Energy Lithium Battery This lithium polymer battery comprises five pouch cells connected in series, featuring a nominal voltage of 18.5V and a capacity of 2100mAh. Designed specifically for high-power remote control applications, it delivers instantaneous power release under heavy load conditions with reliable performance.

Manufactured using lithium cobalt oxide/NCM and smooth aluminium foil layer materials, it features a lightweight, compact design with optimised thermal dissipation, making it particularly suitable for space-constrained remote-controlled models.

This 18.5V 5S 2100mAh lithium polymer battery exhibits low internal resistance, supporting high instantaneous discharge currents from 20C to 120C. Its low resistance enables maximum power delivery without causing significant battery temperature rise. Robust discharge performance ensures intense driving or racing scenarios deliver explosive acceleration, instant throttle response, and stable output, enhancing your experience. For safety assurance, the integrated protection circuit board (Battery PCB) safeguards against overcharging, over-discharging, overcurrent, overtemperature, and short circuits, with protection mechanisms responding within 1 to 3 milliseconds. The entire lithium polymer battery production process occurs on highly automated production lines within medical-grade cleanrooms, where humidity is strictly controlled and comprehensive traceability is supported by an MES system. This battery delivers stable power output and constant voltage for high-performance RC toys such as racing boats, drift cars, rock crawlers, and other applications requiring high-discharge, high-energy solutions. Dimensions, capacity, and discharge current can all be customised.
