At its core, a 3S battery is a type of battery pack that consists of three individual cells connected in series (hence the “3S” part). This connection method is designed to increase the total voltage of the battery while keeping it relatively compact and lightweight. [pdf]
To build a 12V battery pack with 18650 cells, connect four cells in series (3.7V each) to achieve approximately 14.8V nominal. Use appropriate battery management systems (BMS) for safety. Ensure balanced charging and consider using protective cases for safety and longevity. [pdf]
A 12V lithium battery usually has four cells in series. Each cell has a nominal voltage of 3.2V. When you connect four cells (4 x 3.2V), you get a total of 12.8V, which meets the 12V voltage requirement. This battery configuration is widely used in energy storage systems. [pdf]

Less than two years ago, Tesla built and installed the world’s largest lithium-ion battery in Hornsdale, South Australia, using Tesla Powerpack batteries. Since then, the facility saved nearly $40 million in its first year alone and helped to stabilize and balance the region’s unreliable grid. [pdf]
