Designing a Simple 12V Li-Ion Battery Pack with Protection Circuit
Making a 12 V battery pack. To make a battery pack, the first step is to know the nominal voltage of a cell. The cells selected by us have a nominal voltage of 3.7Volts while the charge voltage is 4.2V. So, in order to make a 12 V pack, we require 3 cells connected in series. The image of cells we used is shown below
