Whenever possible, using a single string of lithium cells is usually the preferred configuration for a lithium ion battery pack as it is the lowest cost and simplest. However, sometimes it may be necessary to use multiple strings of cells.
The battery pack will be designed for an average energy consumption of 161.7451 Wh/km. All high voltage battery packs are made up from battery cells arranged in strings and modules. A battery cell can be regarded as the smallest division of the voltage. Individual battery cells may be grouped in parallel and / or series as modules.
Portable equipment needing higher voltages use battery packs with two or more cells connected in series. Figure 2 shows a battery pack with four 3.6V Li-ion cells in series, also known as 4S, to produce 14.4V nominal. In comparison, a six-cell lead acid string with 2V/cell will generate 12V, and four alkaline with 1.5V/cell will give 6V.
Whenever possible, using a single string of lithium cells is usually the preferred configuration for a lithium ion battery pack as it is the lowest cost and simplest. However, sometimes it may be necessary to use multiple strings of cells. Here are a few reasons that parallel strings may be necessary:
The operating voltage of the pack is fundamentally determined by the cell chemistry and the number of cells joined in series. If there is a requirement to deliver a minimum battery pack capacity (eg Electric Vehicle) then you need to understand the variability in cell capacity and how that impacts pack configuration.
The total battery pack voltage is determined by the number of cells in series. For example, the total (string) voltage of 6 cells connected in series will be the sum of their individual voltage. In order to increase the current capability the battery capacity, more strings have to be connected in parallel.
In a small battery with just a few cells in series, the charger voltage is divided nearly equally among the cells. For example, when charging a standard lead-acid starter battery for a car, a constant voltage of 13.5V is applied to it, and each of the six cells within it sees about 2.25V.

[PDF Version]Nominal voltage is the reference voltage used to describe a battery. For LiFePO4 cells, this is typically 3.2V. However, the actual voltage of a LiFePO4 battery fluctuates during use. A fully charged cell can reach up to 3.65V, while a discharged cell may drop to 2.5V. Nominal Voltage: The optimal voltage at which the battery operates best.
The result is a flatter discharge curve. LiFePO4 cells have a nominal voltage of 3.2V, much higher than the 2V for lead acid batteries. This higher stack voltage means less relative change as the battery discharges. For example, a 12V LiFePO4 battery may go from 14.4V fully charged to 12.8V near empty, a change of 12%.
The fully charged voltage is 29.2V, and 20V is the typical low voltage cut-off. The flat voltage zone is from 80% to 20% state of charge. 24V batteries are a convenient option for doubling capacity over 12V systems. For 48V LiFePO4 batteries, the voltage chart is plotted below: As shown in the chart:
The 12-volt LiFePO4 battery's equalized voltage is 14.6V. Low Voltage Cutoff: A low voltage cutoff of around 2.5 volts per cell is recommended for LiFePO4 batteries and discharging below the particular voltage might cause damage to the battery and reduce its lifespan.
Here is a LiFePO4 Lithium battery state of charge chart based on voltage for 12V, 24V, and 48V LiFePO4 batteries. Individual LiFePO4 cells typically have a 3.2V nominal voltage. The cells are fully charged at 3.65V, and at 2.5V, they become fully discharged. Here's a 3.2V battery voltage chart:
The LiFePO4 voltage chart enables users to understand the recommended charge levels for safe charging and acts as a reference point for battery health. Here is a table showing the state of charge (SoC) vs voltage for a typical 12V LiFePO4 battery: A 12V LiFePO4 battery is typically composed of four 3.2V cells connected in series.
