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.

Quality Inspection
Process during production

You can see the quality control details ,it shows how we control the battery quality and ensure battery quality stable.

IQC

When we receive incoming materials from our suppliers, we conduct spot-checks on samples to assess their quality. If the samples pass the quality inspection and meet our standards, we proceed to transfer them to our incoming materials warehouse. From there, our production team will retrieve the approved materials for trial orders and, subsequently, for mass production based on the specified order quantity.

However, if the spot-check reveals that the samples do not meet our quality requirements and are not approved, we will arrange to return these materials to our supplier. This ensures that we maintain high standards and only use materials that meet our quality criteria in our production processes.

IPQC

Before proceeding with trial orders or mass production, we follow a thorough process to ensure the quality of the cells used in our products. This involves spot-checking the capacity of the cells and conducting a comprehensive assessment of their performance, including outward appearance, voltage, and internal resistance. Only cells that meet our quality standards are allowed to move forward to the production line.

Any cells that are found to be non-compliant during the spot-check are identified as “NG batteries” (No Good) and are immediately removed from the production process. These rejected batteries are then returned to the supplier for further analysis and resolution.

Once the approved cells have been soldered with PCM (Protection Circuit Module), we subject the batteries to a rigorous performance check. This assessment includes evaluating voltage, internal resistance, and overcurrent capabilities, among other factors. This meticulous testing ensures that the batteries used in our products meet our high-quality standards and guarantees the reliability and safety of the final goods.

OQC

When the batteries are depleted, we will conduct a thorough assessment of their performance based on the specifications or drawings confirmed by the customer. This assessment includes inspecting the outward appearance, battery label, printing, wires or wire connectors, voltage, internal resistance, and over current protection. If all these parameters meet the required standards, we will proceed with packing the batteries into cartons.

However, if any of these aspects do not meet the specifications, the batteries will be returned to the Quality Control (QC) team for further analysis and necessary adjustments.

In the case of multiple battery packs, such as two cells in parallel, five cells in series, or a 2P6S battery pack, we will subject them to life cycle testing before shipping.

This testing involves simulating real-world usage conditions to evaluate the battery pack’s performance and durability over an extended period. Only those battery packs that pass the life cycle testing will be considered suitable for shipment.

Our commitment to quality assurance ensures that only reliable and fully compliant batteries are delivered to our customers.

Step 1
Design,Manufacturing and book for shipment

We buy the materials to meet your order requests, then start the mass production under our quality control. In the meantime, we will send UN38.3 documents to the forwarder for booking cargo space to avoid any delay.

Step 2
Packing the Boxes for Delivery,stick UN3480 on the carton

After production, our team will pack your order into cartons, stick UN3480 label on the carton.

Step 3
Customs Clearance and Loading

Once your order is packed, we load them onto vans and wait for them to be cleared by Customs.

Step 4
International Delivery

Once cleared, your order will then be shipped to you through international waters. You’ll receive a bill of lading in your email once the cargo is on board and a bill of lading by telex released when your shipment arrives.

FAQ's

Frequently ask questions

If you have any questions, kindly please send email to us.

Yes, Li-polymer batteries are known for their ability to provide high discharge currents, making them suitable for applications with varying power demands.

Suggested Storage temperature:20℃  -30℃. Li-polymer batteries should be stored in a cool, dry place at a partial state of charge (around 40-60% SOC) to prevent degradation. Extreme temperatures should be avoided during storage.

The lifespan of Li-polymer batteries is influenced by factors like usage patterns and charging practices, but they generally have a lifespan of 300-500 charge cycles.

No, Li-polymer batteries are not susceptible to the memory effect, a phenomenon where batteries lose capacity if not fully discharged before recharging.
