The volume of the 18650 li-ion battery with large volume is around 1200mah~3100Mah, and the power of the individual battery is only 800.

Lithium polymer battery (Li-polymer, also known as polymer lithium battery): It has many obvious advantages such as high energy density, smaller size, ultra-thinness, light weight, high safety, and low cost.

Lithium polymer battery, also known as polymer lithium battery, is a chemical battery. Compared with the previous battery, it has the characteristics of high energy, miniaturization and light weight.

Lithium-ion battery, commonly known as "lithium battery", is the battery system with the best comprehensive performance.

The intuitive difference between the 18650 lithium battery and the soft-packed lithium battery is that the 18650 lithium battery is a cylindrical steel shell battery with basically the same size, while the soft-packed lithium battery may have any shape and size.

There is no battery leakage problem, the battery does not contain liquid electrolyte, and uses colloidal solids.
