OEM SERVICE

GSL has been concentrated on manufacturing advanced lithium batteries for over 10 years. Since founded, we have been offering professional R&D capability, patented design, and rich manufacturing experience in designing, developing, manufacturing, and customizing the lithium batteries.

Customers deliver concept products and put forward their requirements.

GSL makes an evaluation about the customized products and arranges the designers to draw the sketches and drawings.

Based on the market evaluation, we make and revise the drawings to follow the trend.

After completing the design, we will show the sketches to customers and confirm the solutions with them.

Once reaching the agreement, we will give the pricing and begin the cooperation relationship with customers.

Then, we will manufacture the sample that customers ask for and deliver it to customers.

Once customers confirm the sample, GSL will start the process of open mold.

We will send a trial order to customers in an efficient manner.

Customized packing design is available in our company.

After everything is prepared, we will start the mass production.

Prompt delivery will be carried out to ensure the goods delivered to customers as soon as possible.
