Lithium ion battery pack, also known as lithium-ion battery pack, is a high voltage and large capacity lithium battery pack obtained by connecting 3.7V lithium-ion single cells in series and parallel according to the needs of various industrial customers. Lithium battery pack is assembled by adding protective plates or other battery auxiliary materials to single or multiple lithium cells. Strictly speaking, this lithium battery assembly process belongs to battery pack, but everyone may have a question, that is, why are lithium battery packs relatively expensive and why?
What are the reasons why lithium battery packs are relatively expensive
1. Capacity requirements for lithium battery packs
When there is no false label for the capacity of lithium-ion batteries, the larger the battery capacity, the higher the corresponding price.
2. Quality and circuit design of lithium battery pack protection board
High quality lithium-ion batteries use high-quality electronic components and protective boards, as well as multiple protection circuit designs. They not only improve the charging and discharging circuits, but also have multiple designs such as constant temperature and voltage, overcharge, overdischarge, overcurrent, and short circuit, creating a safe usage environment for you and your equipment. And those low-priced lithium-ion batteries do not have complete production technology, and safety cannot be guaranteed. Therefore, when choosing, it is necessary to choose a reliable quality lithium-ion battery manufacturer.
3. Quality and safety of lithium battery cells
The quality of battery cells is also an important factor affecting the price of lithium-ion batteries with the same capacity. Different materials of lithium battery cells are also important factors affecting their price differences. Different purchasing channels can also affect their prices. Because some lithium-ion batteries use imported cells, as well as domestically produced ones; There are also differences in the quality of battery cells between A, B, and C; Even some unscrupulous manufacturers choose second-hand and dismantled battery cells, and the price difference between them will be even greater.
4. Differences in material of lithium battery pack casing
The general power supply casing is made of ordinary plastic or ordinary metal materials, which not only have poor heat dissipation, but are also prone to deformation and affect aesthetics. Some brands using inferior materials for the casing may also pose a threat of spontaneous combustion.
