27Ah 66.6 V Lithium Ion Battery Pack High Power Stable Output 5C Max Discharge

Product Specification

66.6V 27000mAh high‑capacity drone battery

1 Product Introduction          

  This 18S 66.6V 27Ah lithium battery pack is built specifically for high power industrial applications that demand stable voltage output, reliable long-term performance and extended cycle life. It supports a maximum continuous discharge rate of 5C and a maximum continuous charge current of 2C, making it well suited for heavy duty UAV, industrial drone, robotics and portable mobile power systems. With a limited charge voltage of 75.6V and a cut off voltage of 49.5V, the pack is engineered to protect individual cells, prevent overcharge and over discharge scenarios, and improve overall safety under continuous, demanding operating conditions.

  The compact physical dimensions of 183 × 90 × 213mm and lightweight design of 6.92kg offer flexible integration into a wide range of different equipment platforms while maintaining excellent high energy density and steady, consistent power delivery throughout the discharge cycle. Every battery pack is manufactured in our factory under strict quality control protocols and undergoes complete, full performance testing before shipment to ensure reliable performance, stable power output and safe operation in field use. As a direct factory supplier, we provide consistent bulk supply capacity, customizable specifications to match unique project requirements and professional technical support for global customers engaged in industrial power applications.
