Product overview

High Discharge/High Power 18.5V 5S 4000mAh LiPo Battery for Truggy toy, Monster Truck toy, RC Vehicle | Battery Manufacturers in China & Battery Supply Factory

18.5V 5S 4000mAh High-Discharge and High-Energy Lithium Polymer Battery is a lithium polymer cell comprising five pouch cells connected in series, featuring a nominal voltage of 18.5V and a capacity of 4000mAh. This battery is engineered to power high-output remote-controlled vehicles requiring substantial torque and extended runtime, including mini truck and monster truck platforms.

Constructed from premium cobalt lithium and soft aluminium foil, this battery achieves high energy density through its lightweight, compact design. An enhanced cell structure ensures efficient thermal management and mechanical stability, withstanding the demanding RC environment of frequent impacts and vibrations.

The 18.5V 5S 4000mAh LiPo battery features low internal resistance and a high rated burst current of 20C-120C, enabling instantaneous maximum power discharge without significant temperature rise. This high-rate discharge capability delivers astonishing acceleration, formidable hill-climbing prowess, and stable power supply during aggressive driving and high-speed runs. To maximise safety, the integrated protection circuit board (Battery PCB) safeguards against overcharging, over-discharging, overcurrent, overheating, and short circuits, with protection mechanisms responding within 1-3 milliseconds. The entire lithium polymer battery manufacturing process is conducted on VTCBATT’s highly automated production lines within medical-grade cleanrooms under strict humidity control, with comprehensive quality tracking throughout via the MES system. It delivers sustained, stable power and constant voltage for off-road vehicles, monster trucks, and various high-performance radio-controlled vehicles. Offering custom battery solutions for diverse RC power equipment, it represents your ideal choice.
