How to assemble large-capacity lithium batteries?

If you want to know how to assemble a large-capacity lithium battery, you must first understand a principle: the series connection of batteries only increases the voltage without increasing the capacity; the parallel connection of the batteries only increases the capacity without increasing the voltage. Here is how to increase the capacity of the lithium battery: for example, you want a 6000mAH, 16V large-capacity battery. If the voltage of a cell is 4V and the capacity is 1200mAH, then you need 20 cells. It is to form a series unit group with 4 batteries to become a 16V battery pack, so that the capacity of a battery pack is 1200mAH, and then connect 5 such unit battery packs in parallel, so that you can get a 6000mAH, 16V battery pack. Large-capacity lithium battery. Points to note when packaging large-capacity lithium batteries: 1. The voltage difference of the lithium battery cells used should not be too large, preferably within 20mV; 2. It is not recommended to use the same type of cells from different manufacturers for assembly, because the manufacturers Due to differences in processing technology and battery material formulations, inconsistent work efficiency between cells will be caused, which will easily damage the battery. 3. Even if the lithium battery cells from the same manufacturer are used, they cannot be mixed with old and new; 4. Even if they are batteries from the same manufacturer, it is recommended to use the same batch of processed batteries; Statement: Some pictures and pictures of articles published on this site The content comes from the Internet.
