- Capacity
In the case of no false standard of lithium-ion battery capacity, generally the larger the battery capacity, the higher the price.
- Protection board quality and circuit design
High-quality lithium-ion batteries use high-quality electronic components and protection boards, as well as multiple protection circuit designs, which not only improve the charging and discharging circuit, but also have multiple designs such as constant temperature and constant voltage, overcharge, overdischarge, overcurrent, and short circuit. Create a safe environment for you and your equipment. And those low-cost lithium-ion batteries do not have perfect production technology, and their safety cannot be guaranteed. Therefore, when choosing, you must choose a lithium-ion battery manufacturer with reliable quality.
- Cell quality and safety
The quality of cells is also an important factor affecting the price of lithium-ion batteries of the same capacity. Different materials of lithium cells are also an important factor affecting the price difference. Different purchase channels will also affect its price. Because some lithium-ion batteries use imported cells, and domestic ones are also available; in terms of cell quality, there are also A, B and C products; even some bad manufacturers choose second-hand cells and disassembled cells. The difference in price will be even greater.
- Shell material difference
Generally, the power supply shell is made of ordinary plastic or ordinary metal material, which not only has poor heat dissipation, but also is easily deformed and affects the appearance. Some brands use inferior materials for the shell, which may cause the threat of spontaneous combustion.
