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 We are selecting a 3.7V battery with a capacity of 1200mAh.
The voltage of a lithium-ion battery is the potential difference between the battery terminals during charging and discharging. The change of voltage directly affects the energy output, charging efficiency and service life of the battery.
For example, a 12V Tubular lead Acid battery might have an LVC of 10.8V. This means the LVC will disconnect the battery from the Load when the voltage drops to 10.8V. For the lithium battery, this cutoff is at higher voltages as the Lithium battery LifePo4 has a voltage of 12.8 Volts, so the cutoff voltage for a Low battery is 11.2 Volts.
