Product Overview

The DMEGC 21700 5000mAh lithium-ion cell is a bare rechargeable lithium-ion cell, not a finished battery pack.

The 21700 designation refers to the cell's physical size format, which is approximately 21mm in diameter and 70mm in length. It is larger than the older 18650 format, allowing for greater capacity per cell.

This is a bare cell and does not include a finished battery management system or complete protection circuit. Use an appropriate BMS, protection system, and dedicated charger when building a battery pack.

Key Features

• 5000mAh rated capacity
• 3.6V–3.7V nominal voltage
• 21700 cylindrical format
• Approximately 21mm × 70mm in size
• Rechargeable lithium-ion cell
• Suitable for BMS-controlled battery packs
• Designed for battery pack assembly and custom applications

Key Benefits

Higher Capacity Per Cell

With a 5000mAh rated capacity, this cell can help battery pack designers achieve their required capacity with an appropriate cell configuration. The actual number of cells required depends on the desired voltage, capacity, current, and physical design of the final battery pack.

Standard 21700 Format

The 21700 format is physically larger than the 18650 format and can provide greater capacity per cell. This makes it suitable for modern battery pack designs where available space and energy requirements allow for the larger cell size.

Flexible Battery Pack Design

The cells can be arranged in different series and parallel configurations to achieve the required voltage and capacity for a particular battery pack design.

Suitable for Custom Pack Assembly

The cell can be considered for applications such as custom battery packs, electric mobility, power tools, energy storage, and other battery-powered equipment, subject to confirmed specifications and application requirements.

Technical Specifications

Important: Charge voltage, discharge limits, exact dimensions, weight, cycle life, chemistry, and protection specifications should be added only after they have been verified against the latest manufacturer's datasheet.

Applications

Common applications for 21700 lithium-ion cells in this capacity class may include:

• E-bikes and electric scooters
• Power tools and portable devices
• Solar and energy storage battery packs
• Custom lithium-ion battery packs
• Battery pack rebuilding and assembly
• Industrial backup systems
• OEM battery pack applications

Before selecting the cell, verify that the battery pack's continuous and peak current requirements are compatible with the confirmed discharge rating of the cell.

Handling & Battery Pack Assembly Guidelines

Lithium-ion cells should be handled and assembled carefully. Always follow the latest manufacturer's specifications and appropriate battery-pack safety practices.

• Use a dedicated lithium-ion charger designed for the cell chemistry and configuration.
• Do not connect the cell directly to a mains power outlet.
• Use an appropriate BMS and protection circuit for the finished battery pack.
• Provide suitable overcharge, over-discharge, and overcurrent protection.
• Do not short-circuit, crush, puncture, disassemble, or physically damage the cell.
• Do not use cells that are swollen, leaking, dented, damaged, or otherwise abnormal.
• Use appropriate pack assembly equipment and procedures.
• Do not mix cells from different manufacturers, models, specifications, or significantly different ages unless specifically approved for the application.
• Inspect cells before assembly and check their condition before use.
• Keep lithium-ion cells away from heat sources, flames, conductive materials, and children.
• Store cells according to the manufacturer's specified temperature, humidity, voltage, and storage requirements.

Safety Disclaimer

Important Safety Information: This product is a bare rechargeable lithium-ion cell, not a finished battery or consumer-ready battery pack. Improper charging, short-circuiting, physical damage, overcharging, over-discharging, overheating, or incorrect assembly may result in fire, explosion, serious injury, or property damage.

• Use the cell only with a suitable charger, BMS, protection circuit, and properly designed battery pack.
• Do not short-circuit, crush, puncture, disassemble, or physically damage the cell.
• Do not use damaged, swollen, leaking, overheated, or otherwise abnormal cells.
• Battery pack assembly should be performed by qualified or experienced personnel using appropriate equipment and safety procedures.
• Always operate, charge, store, and assemble the cell within the manufacturer's specified limits.
• Do not leave lithium-ion cells or battery packs charging unattended.
• Follow all applicable safety requirements and regulations when designing, assembling, transporting, or using lithium-ion battery packs.

The specifications provided on this page are for reference and should not replace the latest manufacturer's datasheet, applicable safety standards, or professional engineering evaluation. The purchaser and battery pack designer are responsible for ensuring that the cell and completed battery pack are suitable and safely designed for the intended application.

Frequently Asked Questions

What is the DMEGC 21700 5000mAh lithium-ion cell?

It is a rechargeable cylindrical lithium-ion cell in the 21700 format, with a rated capacity of 5000mAh and a nominal voltage of 3.6V–3.7V. It is supplied as a bare cell for battery pack assembly.

Is a 21700 cell better than an 18650?

A 21700 cell is physically larger than an 18650 cell and can offer higher capacity per cell. Which format is better depends on the battery pack's available space, capacity requirements, current requirements, and overall design.

Can this 21700 cell replace an 18650 cell?

No. A 21700 cell is not a direct drop-in replacement for an 18650 cell because the physical dimensions are different. Battery holders, enclosures, spacing, and pack layouts must be designed specifically for the selected cell format.

Does the cell come with a protection circuit?

This should be confirmed from the latest manufacturer's datasheet. The product should be treated as a bare cell unless a protection circuit is specifically confirmed.

For battery pack assembly, use an appropriate BMS and protection system.
