Of course!
Mainly small electrical appliances, such as mobile phones, MP3 players, flashlights, electronic products, toys, etc.
With the widespread use of digital products such as mobile phones, notebook computers and other products, lithium-ion batteries are widely used in these products due to their excellent performance, and have gradually developed into other product application fields these last years. In 1998, Tianjin Energy Source Research Institute began commercial production of lithium-ion batteries. Traditionally, people call lithium-ion batteries lithium batteries, but the two batteries are different. Lithium-ion batteries have now become commonplace.
If 100 of these batteries are connected in series, the voltage and current will be the same, i.e. oneis 1A, and 100 batteries connected in series will have the same current of 1A, but the voltage will become higher
If they are connected in parallel, they add up, 10 is a single current
