Batteries based on lithium ion hold many advantages over other battery chemistries, such as high power density and a flat discharge curve, and are the dominant choice in everything from smartphones to electric vehicles.
Depending on the particular Li-ion chemistry used, the voltage of a single cell is between 3.3 V (LiFePO4) and 3.7 V (LiCoO2). A battery pack consists of several cells connected in series—a pack with two cells is a “2S” battery and outputs 7.4 V; a 3S battery outputs 11.1 V; and so on...
