INR18650-MJ1 3500mAh 18650 Lithium-Ion Battery Cell for E-Bikes, Portable Power,

3500mAh Nominal | 10A Max. Discharge | 400-Cycle Performance | Flat-Top 18650 Format

The INR18650-MJ1 is a high-energy 18650 cylindrical lithium-ion cell designed for rechargeable battery packs requiring a combination of high capacity, stable voltage characteristics and reliable power output.

With a nominal capacity of 3500mAh, minimum capacity of 3400mAh, and nominal voltage of 3.635V, the cell provides approximately 12.7Wh of nominal energy in a compact 18650 format. Its maximum discharge current of 10A allows it to support applications that require more than standard low-current battery cells.

The cell is particularly suitable for professionally engineered battery packs used in light electric mobility, portable power equipment, power tools, medical equipment and other rechargeable energy systems.

The specifications above are taken primarily from the uploaded product specification. The document specifies standard charging at 0.5C/1700mA, maximum charging current of 1C/3400mA and maximum discharge current of 10A.

• High-Energy 18650 Format: A 3500mAh nominal capacity provides a strong balance between energy storage and compact cell dimensions.
• 10A Maximum Discharge: Supports battery pack designs requiring higher output current than conventional energy-oriented 18650 cells.
• Stable Power Delivery: The 3.635V nominal voltage and controlled discharge characteristics provide consistent energy output throughout battery operation.
• Reliable Cycle Performance: The specification requires the cell to retain at least 80% of its minimum capacity after 400 cycles under the defined test conditions.
• Wide Operating Temperature Range: The cell supports charging from 0°C to 45°C and discharging from -20°C to 60°C, making it suitable for a variety of indoor and outdoor applications.
• Compact Battery-Pack Integration: The standard 18650 form factor allows multiple cells to be configured into series and parallel battery packs according to system voltage and capacity requirements.
• Low Initial Impedance: Initial AC impedance is specified at ≤40mΩ, measured under the defined test condition.
• Pack-Level Safety Design: The cell specification requires appropriate protection functions to be incorporated into the battery pack and/or charging system, including over-voltage, under-voltage, over-current, short-circuit and over-temperature protection.

For professional battery-pack and system integration use only.

• Use the cell only according to its specified voltage, current and temperature limits.
• Always use a properly designed BMS/protection system for multi-cell battery packs.
• Do not exceed the maximum charge current of 3400mA.
• Do not charge outside the specified 0°C to 45°C temperature range.
• Do not discharge below the specified 2.50V cut-off voltage.
• Do not short-circuit the positive and negative terminals.
• Never directly solder to the cell terminals.
• Do not disassemble, puncture, crush, deform or reconstruct the cell.
• Do not mix different cell types, models, manufacturers or production lots within the same battery pack.
• Do not combine new and used cells in the same pack.
• Inspect every cell before assembly and do not use cells showing physical damage, deformation, leakage or abnormal odor.
• Protect cells from water, seawater, direct sunlight and excessive heat.
• Store cells in a dry, cool environment and follow the specified storage conditions.
• Battery packs should incorporate appropriate over-voltage, under-voltage, over-charge current, over-discharge current, short-circuit and over-temperature protection.
• This cell is intended for professional pack manufacturers and system integrators, rather than direct consumer handling.
