Lithium battery packs are used in solar energy systems, industrial equipment, backup power systems, electric mobility, medical equipment and many other applications. However, not every application requires the same battery configuration. This is why businesses often need to choose between a standard lithium battery pack and a custom lithium battery pack.
A standard battery pack is generally designed around commonly required voltage, capacity, dimensions and electrical specifications. A custom lithium battery pack, on the other hand, is developed according to the specific requirements of the equipment or application. Understanding the difference can help OEMs, system integrators and industrial buyers select the right battery solution.
What Is a Standard Lithium Battery Pack?
A standard lithium battery pack is manufactured using predefined specifications. Its voltage, capacity, cell configuration, dimensions, connectors and other characteristics are generally fixed.
Standard packs are suitable when the equipment already supports commonly available battery specifications. They can offer a straightforward solution for applications where customization is not necessary.
For example, an industrial device may require a commonly available 24V or 48V lithium battery with a particular Ah rating. In such cases, a standard configuration may be sufficient.
What Is a Custom Lithium Battery Pack?
A custom lithium battery pack is designed and manufactured according to the specific electrical, mechanical and operational requirements of the application.
Customization can involve battery voltage, capacity, physical dimensions, cell configuration, connector type, BMS configuration, communication interface, enclosure design and other requirements.
For OEM manufacturers, this approach can be particularly useful because the battery can be designed around the equipment rather than forcing the equipment to accommodate an existing battery format.
Standard vs Custom Lithium Battery Pack
| Parameter | Standard Lithium Battery Pack | Custom Lithium Battery Pack |
|---|---|---|
| Voltage | Predefined | Application-specific |
| Capacity | Standard options | Can be designed according to requirements |
| Dimensions | Fixed or limited options | Customized to available space |
| BMS | Standard configuration | Can be configured for the application |
| Connectors | Standard | Application-specific options |
| Enclosure | Standard design | Customized design possible |
| Production | Faster for common requirements | Requires engineering and development |
| Best suited for | General applications | OEM and specialized applications |
Why Do OEMs Choose Custom Battery Packs?
OEM equipment often has specific space, power and performance requirements. A battery that works well for one machine may not fit another machine because of differences in voltage, current requirements, dimensions or operating conditions.
A custom lithium battery pack allows the manufacturer to specify the battery configuration according to the equipment's requirements. This can help achieve better space utilization and ensure that the battery's electrical characteristics are compatible with the system.
Custom packs can also incorporate an appropriate Battery Management System (BMS) for functions such as cell monitoring, overcharge protection, over-discharge protection, over-current protection and temperature monitoring.
When Is a Standard Battery Pack a Better Choice?
A standard battery pack can be a practical choice when the application already supports an established battery specification and there is no need for unusual dimensions or electrical characteristics.
For businesses looking for a readily available solution for a conventional application, a standard pack can simplify procurement and reduce the need for additional battery engineering.
When Should You Choose a Custom Lithium Battery Pack?
A custom solution becomes more appropriate when your equipment requires a particular voltage, capacity, shape, size or connection configuration. It can also be useful when the battery must operate under specific environmental or performance conditions.
OEMs developing new equipment should consider customization when battery dimensions, energy requirements or communication with the equipment's control system are important parts of the product design.
How Is a Custom Lithium Battery Pack Developed?
The process generally starts by understanding the application's electrical and mechanical requirements. Battery engineers can then determine the appropriate cell configuration, voltage and capacity while considering available installation space and expected operating conditions.
The BMS is selected or configured according to the battery architecture and application requirements. Depending on the project, additional requirements such as connectors, enclosure design, communication protocols and protection features may also be considered.
Before production, the battery pack should undergo appropriate quality and safety checks to verify its performance and compatibility with the intended application.
Which Lithium Battery Chemistry Should You Choose?
Lithium battery chemistry should be selected according to the application's requirements rather than simply choosing the most common option. LiFePO4, for example, is widely considered for applications where long cycle life, thermal stability and safety characteristics are important.
Other lithium-ion chemistries can offer different combinations of energy density, power capability, size and performance. The appropriate chemistry depends on the equipment, operating environment and required battery performance.
Custom Lithium Battery Packs for OEM Applications
For OEM manufacturers, battery customization can be particularly valuable when the battery is an integrated part of the product. A manufacturer can work with a battery supplier to define the required voltage, Ah capacity, dimensions, cell configuration, BMS and other technical specifications.
6A specialized battery manufacturer such as Voltizo Industries can work with businesses that require application-oriented lithium battery solutions for OEM, industrial, solar and energy-storage requirements.
Frequently Asked Questions
What is the main difference between standard and custom lithium battery packs?
A standard battery pack uses predefined specifications, while a custom lithium battery pack is designed around the specific electrical, mechanical and operational requirements of the application.
Is a custom lithium battery pack better than a standard battery?
Not necessarily. A standard battery can be suitable for conventional applications. A custom pack is more appropriate when the equipment has specific voltage, capacity, size, BMS or connectivity requirements.
Can the voltage and capacity of a lithium battery pack be customized?
Yes. Depending on the battery design and application requirements, the voltage and capacity can be configured using an appropriate cell arrangement.
Can the BMS be customized?
The BMS can be selected or configured according to the battery's electrical architecture and application requirements. Features can include protection functions, monitoring and, where required, communication capabilities.
Are custom lithium battery packs suitable for OEM manufacturers?
Yes. Custom battery packs are particularly useful for OEMs because the battery can be designed around the equipment's available space, power requirements and operating conditions.
How do I choose between a standard and custom lithium battery pack?
Start with your equipment's voltage, current, Ah capacity, dimensions, operating environment, expected runtime and BMS requirements. If these requirements match an existing battery configuration, a standard pack may work. If they do not, a custom solution may be more suitable.
