16.8V 3500mAh 18650 Lithium Battery Pack – 4S1P Rechargeable Power Source with Built-in BMS in Pakistan

Overview

When designing custom cordless tools, portable LED floodlights, mini CCTV backup systems, or robotics prototypes, finding a reliable multi-cell energy pack with the correct voltage and current capacity is essential. Assembling loose 18650 cells manually without proper spot welding and protective circuitry can be hazardous and unreliable. The 16.8V 3500mAh 18650 Lithium Battery Pack provides a pre-built, factory-tested 4S1P energy solution equipped with an integrated Battery Management System (BMS), ensuring safe, stable, and ready-to-use power for demanding electronic applications.

Key Features

• Optimized 4S1P Configuration: Series arrangement of four high-capacity 18650 cells delivers a nominal 14.8V to maximum 16.8V fully charged output.

• Integrated Protection Circuit (BMS): Built-in safety board guards against overcharging, deep discharging, over-current, and short-circuit faults.

• Compact Shrink-Wrapped Build: Sturdy PVC outer insulation protects internal cell connections and makes installation into project enclosures clean and straightforward.

• Pre-Soldered Lead Wires: Fitted with durable connection wires for quick and secure integration into your circuits or power ports.
