High Capacity Lithium-ion 26650 3.7v 5000mAh Cylindrical Lithium Battery High Rate Long Cycle Power Battery

Description

Technical Excellence & Cell Overview

As energy requirements for portable equipment increase, the Lithium-ion 26650 has become the go-to solution for engineers seeking a balance of volume and power. This cylindrical cell utilizes advanced NCM (Nickel Cobalt Manganese) chemistry, which allows for a high energy-to-weight ratio while maintaining safety.

• Cell Type: Grade-A Cylindrical Lithium-ion (Li-ion)
• Model: 26650 (Dimensions: 26mm diameter x 65mm height)
• Nominal Capacity: 5000mAh (High energy density)
• Voltage: 3.7V Nominal (4.2V fully charged)
• Cycle Life: Designed for 1,000+ full charge/discharge cycles with minimal capacity fade.
• Configuration Flexibility: The Lithium-ion 26650 is frequently used in Series (S) and Parallel (P) configurations to create high-voltage or high-capacity packs. Common assemblies include:
• 12V Packs (3S/4S): Used for replacing lead-acid batteries in small vehicles.
• 24V/36V Packs: Ideal for industrial AGVs and electric mobility.
• Parallel Stacks: Achieving 10Ah, 20Ah, or higher for long-runtime energy storage.

Versatile Application Scenarios

The high-rate discharge performance of our Lithium-ion 26650 makes it indispensable across multiple high-growth industries:

• Portable High-Lumen Lighting: Powering professional-grade flashlights and searchlights that require sustained high current.
• Electric Mobility: Used in e-scooters, electric wheelchairs, and balance bikes where durability is paramount.
• Solar Energy Storage: Ideal for solar street lights and off-grid home storage systems due to its excellent thermal stability.
• Power Tools: Providing the “punch” needed for cordless drills, saws, and industrial gardening equipment.
• Medical Equipment: Serving as a reliable backup power source for portable oxygen concentrators and diagnostic tools.
