Lithium-ion battery packs are complex assemblies that include cells, a battery management system (BMS), passive components, an enclosure, and a thermal management system.
Lithium-ion battery packs include the following main components: Lithium-ion cells – The basic electrochemical unit providing electrical storage capacity. Multiple cells are combined to achieve the desired voltage and capacity. Battery Management System (BMS) – The “brain” monitoring cell conditions and controlling safety and performance.
Lithium-ion battery cells come in three main formats: cylindrical, prismatic, and pouch cells. Cylindrical battery cells were the first lithium-ion batteries to achieve mass production. They're made by winding the cathode, anode, and separator in a specific order into a cylinder shape and then housing it in a metal casing.
The voltage of a lithium-ion battery cell is typically around 3.7 volts. The voltage of a lithium-ion cell is a crucial parameter as it influences the overall voltage of a battery pack when multiple cells are connected in series.
A lithium-ion battery module is a group of interconnected battery cells that work together to provide a higher level of voltage and capacity. Modules are designed to facilitate efficient cooling and thermal management, ensuring that the temperature within the battery remains within safe operating limits.
In the case of lithium-ion cells, lithium ions move between the positive (cathode) and negative (anode) electrodes during charge and discharge cycles. Different combinations of materials result in batteries with varying energy density, voltage, cycle life, and safety features. The voltage of a lithium-ion battery cell is typically around 3.7 volts.
There are also significant differences in cost structure. In the total battery pack cost, battery cells account for the largest portion at around 50%, with cathode materials being the main cost component of the battery cells. At the battery module level, costs increase due to structural components and connectors.
Automotive battery packs used for electromobility applications consist of a large number of individual battery cells that are interconnected. Interconnection of the battery cells creates an electrical and mechanica.

In this article, we'll explore the basics and provide detailed, step-by-step instructions on how to connect lithium batteries in series, parallel, and series-parallel configurations.
Lithium-ion battery pack circuit diagrams provide a detailed overview of the individual cells and their connections within the battery pack. Without this information, it would be almost impossible to understand how different components of the system interact.
Lithium batteries are connected in series when the goal is to increase the nominal voltage rating of one individual lithium battery - by connecting it in series strings with at least one more of the same type and specification - to meet the nominal operating voltage of the system the batteries are being installed to support.
Connecting multiple lithium batteries into a string of batteries allows us to build a battery bank with the potential to operate at an increased voltage, or with increased capacity and runtime, or both.
You should connect lithium batteries in series when your device requires a higher voltage than a single battery can provide. For example, if your device operates at 7.4V, connecting two 3.7V batteries in series would be appropriate. This setup is commonly used in applications like electric scooters, drones, or other high-voltage devices.
Voltage and Current Testing: Use a multimeter to ensure the pack operates within safe parameters. Assembling a lithium battery pack requires careful planning, the right tools, and a thorough understanding of series and parallel configurations.
The modern world is powered by lithium-ion batteries, and one of the most critical components of these batteries are their circuit diagrams. Lithium-ion battery pack circuit diagrams provide a detailed overview of the individual cells and their connections within the battery pack.
