What is a lithium battery pack? What is a large-capacity lithium battery pack?

What is a lithium battery pack? What is a large-capacity lithium battery pack? In daily life, we often hear many friends say lithium battery packs, lithium battery packs with large capacity. What are they? How are they related to lithium batteries? Let the lithium battery manufacturer and polymer manufacturer Shenzhen Jiefucheng tell you: What is a lithium battery pack? Lithium battery packs are also called lithium battery packs. According to the needs of customers in different industries, 3.7v lithium-ion battery cells are connected in series to form a high-voltage large-capacity battery pack. In the assembly process of lithium batteries, the following points should be noted: 1. The capacity, internal resistance, voltage and other parameters of each lithium battery should be matched. At the same time, take out the battery with inconsistent self-discharge. 2. Reasonably design the shape of the protection board, charge and discharge protection voltage value and overcurrent protection value. 3. Consider the direction of the nickel bars and lead of the battery pack to prevent short circuits and short circuit risks. 4. After the lithium battery is packaged, the performance of the battery should be simulated according to the actual situation, and the basic performance of the battery should be tested at the same time. Our engineers will provide you with a complete solution, specific voltage and capacity requirements of lithium batteries. II. What is a large-capacity lithium battery pack? A large-capacity lithium battery is a popular name that has a larger capacity than a lithium battery pack. There is no specific agreement on how high the voltage and capacity of the large-capacity lithium battery are. According to our statistics, a lithium battery pack with a capacity of more than 5Ah can be called a large-capacity lithium battery. The single voltage of the lithium battery is 3.7v, and the single capacity ranges from tens of milliamps to tens of amperes. For example, the 18650 lithium battery we often use is 3.7v2200mah. In general, the voltage range of a 12V device is 9-15v, while the voltage range of a 11.1v19.8ah lithium battery pack is 9-12.6v. The lithium iron phosphate battery we mentioned is 26650-3000mah, and the voltage is 3.2v3ah. If our customer wants a 12V20Ah battery pack, we can use 26650-3ah batteries for 4 7 series and get a 12.8v21ah battery pack. The battery voltage range is 9.2v-14.6v.
