Customized Battery Pack Service
Our 21700 3.6V 5000mAh NCM rechargeable battery cells can be used to develop customized lithium-ion battery packs for applications requiring high energy density, reliable power output, and flexible pack configurations. We provide OEM and ODM battery pack services, from cell selection and pack design to prototyping and mass production.
Customized Voltage & Capacity: We can configure the 21700 5000mAh NCM cells in different series and parallel combinations according to your required voltage and capacity.
BMS & Protection System: A suitable Battery Management System (BMS) can be integrated to provide protection against overcharge, over-discharge, overcurrent, short circuit, and over-temperature. Smart BMS options with Bluetooth, CAN, RS485, or other communication functions can also be considered.
Application-Specific Battery Design: Our engineers can recommend the appropriate battery configuration based on the actual application, considering voltage, capacity, discharge current, operating temperature, dimensions, charging method, and expected operating time.
Packaging
Inner Packaging: Cells are securely arranged in customized battery trays or insulating packaging to prevent movement and contact between cells. The packaging quantity can be adjusted according to order requirements.
Carton Packaging: The protected cells are packed into strong export cartons with suitable cushioning materials designed to withstand normal handling, loading, unloading, and transportation.
Pallet Packaging: For large-volume orders, cartons can be securely stacked on export pallets and wrapped with stretch film. Additional edge protection and strapping can be used to improve stability during long-distance transportation.
Frequently Asked Questions
What battery chemistry does this cell use?
The cell uses NCM (Nickel Cobalt Manganese) lithium-ion chemistry, which offers a good balance of energy density, power performance, and cycle life.
What does 3C discharge mean?
A 3C discharge rate means the cell can theoretically discharge at up to three times its nominal capacity. For a 5000mAh cell, 3C corresponds to approximately 15A continuous discharge, subject to the manufacturer's specific datasheet and operating conditions.
Can this 21700 battery cell be used for high-power applications?
Yes. With a 3C discharge capability, the cell is suitable for applications requiring relatively high output power, such as power tools, electric mobility devices, portable power equipment, robotics, and other customized battery packs.
Which certifications are offered?
UN38.3, MSDS, CB and CCC can be provided according to project requirements.
