18650 cells and lithium polymer cells are different from the original data. The original data of 18650 cells is based on lithium iron 磷酸, lithium manganate and ternary options, while the original data of lithium polymer cells is usually composed of lithium cobaltate, lithium manganate, and lithium ternary lithium ternary materials. The former one is single and pure, while the latter one is rich.
The safety between the two is also very different. The 18650 cell is important because the steel shell packaging design makes it likely to cause trouble when the product fails. However, beginners who want to assemble are likely to be able to tell whether the 18650 cells they traded have passed the product. For beginners, 18650 cells are difficult to get started and are not recommended.
Generally speaking, in the case of assold battery assembly, the cells selected by beginners of lithium battery packs are lithium polymer cells, which are important because of their high energy ratio and high safety, and important is that high safety is important. In the final analysis, it is possible to better do a good job in your favorite event by maintaining your own personal insurance.
