The protection of customized lithium-ion batteries must include at least the upper limit of charging voltage, the lower limit of discharge voltage, and the upper limit of current.

　　In addition to custom-made lithium-ion batteries, custom-made lithium-ion battery packs usually have protective plates that are essential to provide these three types of protection. But these three protections on the protection board are obviously not enough. Lithium-ion battery explosions are still common worldwide. In order to ensure the stability of the battery system, it is necessary to more carefully disassemble the cause of the battery explosion and better protect the use of lithium-ion batteries.

　　To choose a customized lithium-ion battery manufacturer, the customized lithium-ion battery manufacturer must have a certain understanding of the style requirements of lithium-ion batteries, such as battery size customization, performance customization, and environmental customization. The safety and reliability of lithium-ion batteries are of paramount importance. Everyone should know that lithium-ion batteries have potential safety hazards such as spontaneous combustion and explosion, and inferior lithium-ion batteries also have safety hazards. Therefore, the safety and reliability of lithium-ion batteries are the most basic requirements.
