INR18650-MH1 3200mAh High-Capacity 18650 Lithium-Ion Battery Cell with 6A Continuous Discharge and 1000-Cycle Performance

The INR18650-MH1 is a high-capacity 18650 rechargeable lithium-ion battery cell designed for battery packs that require a practical balance of energy density, stable power delivery, compact size, and long service life.

With a 3200mAh nominal capacity, 3.7V nominal voltage, and 11.8Wh nominal energy, the MH1 provides reliable energy for medium-power applications. Its 6A continuous discharge capability makes it well suited to two-wheel mobility, robotic cleaning equipment, portable electronics, and other battery-powered products where consistent output and operating time are important.

The cell also demonstrates strong cycle performance, retaining at least 80% of initial capacity after 1,000 cycles under the specified 0.3C/0.5C test condition. A separate 0.5C/0.5C cycle test specifies at least 70% capacity after 500 cycles.

Its standardized 18650 cylindrical format and compact dimensions make it suitable for multi-cell battery pack designs across mobility, robotics, consumer electronics, and portable power applications.

• 3200mAh High-Capacity 18650 Cell - The 3200mAh nominal capacity provides a useful combination of compact form factor and energy storage, making the MH1 suitable for applications where battery runtime is important. The specification defines a minimum capacity of 3100mAh.
• Stable 6A Continuous Discharge - With a specified 6A continuous discharge current, the MH1 is designed for moderate-power battery packs requiring dependable current output without moving to larger-format cells.
• Long Cycle Life - Under the specified test conditions, the cell maintains at least 80% of initial capacity after 1,000 cycles, making it suitable for products expected to undergo frequent charge and discharge cycles.
• Compact 18650 Form Factor - The 18.4mm maximum diameter and 65.2mm maximum height allow designers to build compact multi-cell battery configurations for mobility products, robotic devices, and portable electronics.
• Wide Operating Temperature Range - The specified discharge temperature range extends from -30°C to 60°C, supporting battery-pack designs intended for a variety of indoor and outdoor operating environments.
• Proven Pack-Oriented Design - The product specification provides dedicated pack design parameters for E-bike and E-Scooter applications, including charging and discharge voltage guidelines, making it particularly relevant for two-wheel battery-pack development.

The INR18650-MH1 can be considered for a broad range of medium-power rechargeable battery systems, particularly where compact size, capacity, cycle life, and stable discharge performance are important.

The MH1 occupies a useful position between high-capacity energy storage cells and high-power cells. Rather than focusing on extreme pulse current, its specifications emphasize usable capacity, moderate continuous discharge, compact 18650 packaging, and long cycle performance.

For battery manufacturers and OEM/ODM developers, this makes the cell suitable for products where runtime and lifecycle are more important than extreme peak power.

Typical configurations can be customized according to the application's required voltage, capacity, discharge current, physical dimensions, and BMS architecture.

The MH1 is a bare rechargeable lithium-ion cell, not a complete protected consumer battery. Battery packs must therefore incorporate appropriate protection and control functions.

• Over-voltage protection
• Under-voltage protection
• Over-charge current protection
• Over-discharge current protection
• Short-circuit protection
• Over-temperature protection
• Cell voltage monitoring
• Cell balancing for multi-cell packs

The source specification specifically requires appropriate protection functions to be incorporated into the battery pack and/or charging system.

Cells should be handled by qualified battery-pack manufacturers or system integrators. The specification also prohibits direct soldering to the cell and requires appropriate insulation and pack-level design controls.
