Lithium Battery Customization

Custom lithium battery packs are a collection of individual lithium batteries that have been configured and connected in a specific way to meet the energy needs of a device or application. They offer a higher level of energy output and a longer lifespan than standard lithium batteries.

Selecting the appropriate custom lithium battery pack requires careful consideration of a variety of technical specifications. This blog will discuss the key factors that influence the selection process.


The size of a lithium battery is important, because it determines the runtime of a device. When designing a lithium-ion battery, it is important to choose the right capacity, as well as the right internal resistance. The battery should be able to handle the peak load current and discharge cycles of your product. This will ensure that the battery will last for as long as possible.

The first step in creating a custom lithium battery is finding a manufacturer who specializes in this type of technology. Look for a company that offers a wide range of custom energy solutions and has an experienced R&D team. It is also recommended to choose a company that uses only new cells, as recycled batteries have shorter cycle times and less life.

Custom lithium battery packs are a great option for powering devices and applications with unique energy requirements. They provide a higher level of energy output and have a longer lifespan than standard lithium batteries. They can also be designed to fit the specific Lithium battery customization dimensions of a device, which can result in a more compact and streamlined energy solution.

Custom lithium batteries are also a great way to promote your brand. Having your logo printed on the battery will help customers associate your product with your brand. This will increase brand recognition and increase the likelihood of future sales.


Lithium batteries are available in a variety of shapes, sizes, and specifications. When choosing a lithium battery for a particular project, it is important to consider the specific requirements of the device and application. This will help you determine whether a cylindrical or flat design is the best fit. Additionally, you should choose a lithium battery that is suitable for the temperature conditions in which it will be used. Lithium-ion cells react with water to form hydrogen gas, which can cause a thermal event and fire. To avoid this, a non-aqueous electrolyte is used to separate the anode and cathode materials.

Cylindrical batteries are the most popular choice for multi-cell battery packs due to their symmetrical mechanical form and efficient packing. They also have a robust structure and minimize stress and internal pressure concentration. Moreover, they offer higher energy density than flat cells.

Another type of lithium battery is the pouch cell, which was introduced in 1995. This type of battery doesn’t have a hard exterior casing and is instead sealed in an aluminum plastic film (laminate). It is more flexible than the prismatic cell and offers superior energy density. However, it can swell during use, making it more vulnerable to penetration.

Finally, thin film batteries are very thin and flexible and resemble a sheet or strip. They are commonly used for wearable devices and portable applications that need high load currents. They are also more affordable than bike battery a traditional lithium-ion battery and have excellent cycle life.

Battery Management System (BMS)

The BMS is responsible for monitoring and managing the state of charge (SoC) and state of health (SoH) of a battery pack. The BMS is also tasked with overseeing charging and discharging of the lithium-ion cells, protecting the battery from functional safety issues like copper dendrite formation, and ensuring that the pack never exceeds specific voltage threshold limits.

To prevent these problems, the BMS must have robust and fast-reacting algorithms based on rules or logic to detect predefined threshold violations and react accordingly. However, rules-based algorithms lack the flexibility and agility to take into account the unique operating conditions of your battery system.

In addition, the BMS must be able to accurately measure cell voltages and currents and calculate state parameters based on these measurements. It must also be capable of detecting internal faults in the batteries by evaluating metrics like peak rates of change for monitored parameters. This allows the BMS to flag issues and trigger handling protocols much sooner, preventing thermal runaway conditions.

The most popular BMS topology is centralized, where a single control board manages all the cells in a battery through a communication network. This type of system is less expensive than other topologies, according to Grand View Research, but it also offers a limited range of functionality.


A lithium battery pack is a group of individual lithium batteries that have been configured and connected together in a specific way to meet the energy needs of a particular device or application. Custom packs can offer higher energy output and longer lifespan than standard lithium batteries, making them ideal for devices with unique power requirements. They can also be designed to withstand special working conditions, such as high temperatures or low temperatures.

To customize a lithium battery, the equipment manufacturer needs to provide the lithium battery customization factory with important details such as the power consumption parameters, voltage operating range, charging method, raw materials used, size and shape of the battery, and its interface mode. The battery customization factory will then propose a design that meets these requirements. The custom lithium battery will need to be tested and analyzed to ensure it meets the product’s performance and safety requirements.

When selecting a lithium battery customization factory, it is important to choose one with professional experience. A reliable factory will be able to help the product company choose the right battery type, cell, and BMS to meet its needs. In addition, a reputable battery factory will have the expertise and capability to deliver customized products in small quantities. They will also be able to provide a wide variety of battery accessories, such as safety connectors and plastic cases.
