Product Overview

The INR18650N20A20 is a 3.7V 2000mAh high-discharge 18650 lithium-ion battery designed for power tools, industrial equipment, and high-load portable devices.
It delivers up to 20A continuous discharge with low internal resistance, supporting stable output under demanding current profiles.
The cell achieves 400 cycles at 10A discharge with ≥80% capacity retention, balancing power density and service life.
With a wide operating temperature range and multiple international certifications, this model is suitable for OEM battery pack designs requiring reliability, safety, and consistent high-current performance.



Key Advantages

  • 20A continuous discharge capability for high-power equipment

  • Low internal resistance (≤18mΩ) reduces voltage drop and heat buildup

  • Proven cycle life under both medium and high current conditions

  • High volumetric and gravimetric energy density for compact pack design

  • Stable performance across a wide temperature range from -20°C to 75°C

  • Certified for global OEM supply chains (UL, CB, CCC, KC, BSMI, BIS)


Product Description

The INR18650N20A20 lithium-ion battery is engineered for applications that require sustained high discharge currents without compromising reliability or safety.
With a nominal voltage of 3.7V and a capacity of 2000mAh, it provides a balanced solution for systems where power output is more critical than maximum energy storage.

This cell is intended for B2B, OEM, and ODM battery pack manufacturing, particularly in power tools, industrial devices, portable medical equipment, and energy storage subsystems.
Its electrical characteristics, cycle performance, and thermal tolerance make it suitable for both single-cell and multi-cell pack configurations when integrated with appropriate battery management systems.
