How to choose 18650 lithium battery pack?

What is 18650 lithium battery pack?

The 18650 lithium battery pack is a product that uses the battery manufacturing process to assemble different numbers of lithium cells of the 18650 lithium battery through a protective circuit board. The most critical components in the 18650 lithium battery include: 18650 battery cells, protection board circuit boards, and battery assembly process.

18650 in a lithium battery refers to the external size, 18 is a diameter of 18 mm, 65 is a length of 65 mm, and 0 is a cylindrical battery. This product is a standard lithium-ion battery developed by Japan's SONY company to save costs, and it is named 18650. The 18650 lithium battery is a typical cylindrical lithium battery, which has received widespread attention.

1. 18650 core refers to a cylindrical cell with a diameter of 18 mm and a length of 65 mm.

2. The structure of the protection circuit board is:

IC: control
MOS: switch
Negative Temperature Coefficient Resistor
ID: identifiable resistor
Fused fuse with protective function

3. Battery process line

With the development of PACK technology, various connection methods are constantly improving, from the initial wire welding, to nickel sheet welding, and then to laser welding, all of which are constantly developing, and the battery production process is also constantly improving. , a mature and professional assembly line is the key to lithium batteries. PKcell battery has a complete process line.


How to choose 18650 lithium battery pack?

1. 18650 high quality batteries

High-quality 18650 lithium battery packs should use first-class brand cells, and require qualified and stable manufacturers to provide high-quality single cells. Only in this way can the quality of 18650 lithium batteries and high-quality batteries be ensured.

2. Connect high-quality protection circuit board

A good protection panel should have the functions of overcharge, overdischarge, overcurrent, short circuit, temperature, internal resistance, power consumption, etc. Therefore, when we buy, we must choose high-quality big brands, which can ensure the safety of lithium batteries. All circuit boards of Pkcell battery are of very good quality, contact us for sample testing

3. Carried out in a mature and professional production process

The manufacturing process of the 18650 lithium battery is the key. It must have advanced equipment, high-tech personnel, mature management, and strict manufacturing process to ensure that the 18650 lithium battery is not damaged in key links such as welding, testing, aging, and pre-shipment testing. There will be any mistakes, so that the 18650 lithium battery pack will be produced.
