12V lithium ion battery

Why choose lithium-ion battery pack?

  1. Li-ion battery is small in size and light in weight.
  2. The uniform voltage of a single battery can reach 3.7V or 3.2V, which is relatively equal to the series voltage of 2-4 nickel-hydrogen batteries and nickel-isolated batteries.
  3. Lithium-ion battery packs have high energy density and long life.
  4. Lithium-ion battery materials are free of any toxic and harmful substances and will not cause any pollution to the environment. It is recognized as a green battery in the world.

What are application of lithium-ion battery packs?

lithium battery pack requires a high degree of battery consistency (capacity, internal resistance, voltage, discharge curve, life). The cycle life of the battery pack is lower than that of a single battery. After the lithium battery pack PACK is formed, the battery voltage and capacity have been greatly improved, and it must be protected by charging equalization, temperature, voltage, and overcurrent monitoring. The battery pack must meet the voltage and capacity requirements of the design.

Lithium Battery Pack Manufacture Process

Consultants

To understand the real demands of the lithium-ion battery pack, you need to provide the lithium battery size, electrical performance requirements, output requirements, and functional information.

Quick Response

Evaluate a solution and quote the known parameters provided by the customer, also provide full datasheet for reference. We will consider the cell selection, circuit and structure design to final assembly.

Sampling

After the customer’s approval, we will start to make samples for the lithium-ion battery pack, and provide charging and discharging cycle curve and data.

Sample Test

Before delivering out, we definitely do battery pack aging test. Assist and track customer test results, as well as customer’s overall equipment operation effect.

Certificate Proceed

We will discuss with customer certificate works based on the final country and applicate requests. It may be MSDS, UN38.3, IEC62133, KC, PSE, etc.

Mass Production

Develop process documents and BOM sheet, purchase materials, arrange staff production, quality personnel monitoring, and random inspection, and package and shipment.
