Applications for Lithium ion Battery Packs

Factory and Capability View

Focus on Lithium ion battery packs for 9+ years

The Battery Manufacturing Process

Here's a detailed breakdown of our manufacturing process that makes sure the battery quality is good.

1. After the samples and battery specification are confirmed, we will start mass production soon after receiving the customer order and deposit.

2. Evaluate supplier, and test the quality of cell and PCM samples, till samples are approved. 

3. Buy all the materials from the qualified supplier which are CE, ROHS,UKCA certified.

4. Spot-check cells capacity and fully check the voltage and internal resistance of cells before mass production.

5. Start mass production.

6. Fully check  the battery quality during mass production, called IPQC.

7. After  batteries are finished, fully check their performance, such as appearance, voltage, working current, over-working current, internal resistance etc. For the multiple battery pack, we add the life cycle testing before shipment.

8. Package and shipment.
