Minimum & Maximum Voltage Range For 18650

What Is The Minimum & Maximum Voltage Range For 18650?

Understanding the voltage range of a 18650 cell is crucial in learning how to build battery packs. Since lithium batteries have a rather wide working voltage range this is increased when putting multiples of cells in series. Having a good understanding of this working voltage range will help figure out the working voltage rang of a battery pack.
