As technology advances, more devices require high capacity or high voltage. Modular lithium iron phosphate batteries have emerged as an advanced energy solution, but this is not the only reason for its generation. Modular battery packs refer to the assembly of multiple cells into one or more battery modules, and then connecting multiple battery modules in series or parallel to increase capacity or voltage, forming a large battery pack.
In general, modular batteries are configured as standalone batteries which can be master or slave batteries. Next, we will explore the differences between lithium battery packs and modular battery packs, explore their pros and cons, and identify the most suitable applications, so that we can better understand the design concept of modular batteries.
What is the Difference between Custom Battery Pack and Modular Battery Pack?
The key difference between custom battery packs and modular battery packs lies in their flexibility and adaptability.
The Distinguishing Feature of Custom Battery Pack:
A custom battery pack is specifically designed and manufactured for a specific application or device and the custom li ion battery solution is unique. It is tailored to meet the specific power requirements, size limitations, and performance needs of the device. Custom battery packs are designed from concept and production. Each component needs slight customization even a special production process to ensure optimum performance and compatibility. They cost more and the custom battery pack manufacturer and customers should spend more time to reach an agreement on the custom battery pack design and battery pack assembly before the customer places the order.
The Core Feature of Modular Battery Packs:
On the other hand, a modular battery pack is a type of pre-designed and pre-engineered battery modular that can be easily combined to create a battery pack with the desired capacity and configuration. They are standardized and interchangeable, allowing for flexibility in design and quicker assembly.
Custom battery packs are tailored for specific applications, while modular battery packs make it easy to increase the voltage and capacity ranges in series and parallels.

What are the Pros and Cons of Modular Battery Packs?
Pros of Modular Battery Packs
Scalability: Modular battery packs allow for easy expansion or reduction by series and parallel. This flexibility enables the system to be tailored to changing energy storage requirements without replacing the entire pack.
Reliability: The modular design of battery packs increases reliability. If a single modular battery packs fail, they are isolated without affecting the entire system’s performance.
Easy Maintenance: Modular battery packs simplify troubleshooting and maintenance. When a problem occurs, it is easier to identify the faulty module and reduce the maintenance costs.
Discharge performance: High-speed charge/discharge performance of up to 5C can be achieved, and the BMS can realize high-power discharge with multiple control and protection functions.
Safety standards: With well-designed safety features in line with aviation safety standards, modular batteries prioritize safety as a paramount consideration, instilling confidence in their reliable performance.
Easy to Ship: The modular battery is easier to ship even if you can take the modular battery by plane when the modular battery is disassembled into smaller batteries.
Customization: Modular packs offer customization options. By connecting modules in series and parallel configurations, the overall energy capacity and power output can be scaled to meet specific application requirements.
Cons of Modular Battery Packs
Higher Cost: Compared to standard battery packs, modular battery packs can come with a higher upfront cost. The modular battery packs have a CMU control system, which increases the cost. The battery pack solution is built with a smart battery management system.
Complexity: Managing and monitoring a modular battery pack system can be more complex compared to the standard packs. The interconnection of modules and ensuring their proper functioning requires advanced monitoring systems.
More physical spaces: Modular battery packs have the potential to require more physical space compared to custom battery packs.
Compatibility: When expanding or replacing modules, compatibility issues may arise. Ensuring that new modules integrate properly with existing ones can require additional efforts in terms of compatibility testing and system integration.
It is important to consider the pros and cons when evaluating the suitability of modular battery packs for specific applications. While the advantages of scalability, reliability, and customization are significant, the potential drawbacks of higher cost, increased complexity, and space requirements need to be carefully weighed in each scenario.
What Popular Applications Are Modular Battery Pack Solutions Utilized For?
Modular battery packs play a crucial role in various specialized applications. Let’s explore some of these fields where modular batteries are incredibly valuable.
Communication Power System
- Communication Power System: In the realm of communication power systems, a reliable and continuous power supply is essential. With the support of modular batteries, communication systems can maintain their power requirements, even during emergencies.
