Design

Engineers will determine the battery configuration, BMS, and other functional modules based on your needs and applications, ensuring the design meets specific power consumption, capacity, and reliability.

Purchase

We have been collaborating with well-known suppliers in the industry for the long term, ensuring that the voltage, capacity, charge-discharge cycle numbers, and other parameters of each battery cell batch meet the project’s requirements.

Sample

After the battery sample production is completed, we will send the sample to the customer for testing. Once the test passes, we will proceed to the next step of mass production.

Production

The Delong factory has three advanced production lines, each with state-of-the-art equipment and testing instruments. Workers strictly follow the production process to assemble and test battery packs, ensuring the timely delivery of the battery packs.

Inspection

Lithium batteries will undergo appearance inspections, voltage tests, charge and discharge performance tests, temperature tests, safety performance tests, environmental adaptability tests, cycle life tests, and tests for specific scenarios and requirements before leaving the factory.

Package

We deeply understand the requirements for transporting lithium batteries, including packaging methods and materials, protective measures, labelling and international regulations. Our products meet international certifications and can be delivered smoothly.
