Custom Battery Pack Solution

As a leading custom battery pack manufacturer, CMB specializes in designing and manufacturing custom battery packs for a wide range of industrial applications. Our focus is on delivering durable, cutting-edge custom lithium battery packs for complex and extreme working environments.

CMB engineers leverage the latest advanced technology and innovative patents to ensure long-lasting reliability. We custom-manufacture lithium-ion battery packs using 18650 and 21700 lithium-ion (Li-ion) cells, LiFePO4 (LFP) cells, and lithium polymer (LiPo) cells. Additionally, we produce customized battery packs capable of withstanding extreme high and low temperatures. Learn more about our custom li ion battery pack options below.

Our Battery Pack Assemblies Process

CMB’s Battery Pack Assemblies Process involves evaluating battery chemistries, casing design, and management systems based on customer needs. The process encompasses basic and advanced lithium battery pack designs, each tailored to specific requirements.

Lithium-ion battery manufacturing follows cell sorting, assembly, and insulation stages, ensuring high performance, safety, and longevity of custom battery packs.

Our Engineering Team

At the core of CMB’s work is our team of expert engineers. Our Chief Technology Officer (CTO) has more than 15 years of experience in the lithium-ion battery industry and has previously worked with CTAL, BYD, and BAK (three well-established battery pack companies). The CMB Engineering Department is composed of 13 additional skilled and experienced team members who contribute to the design, manufacturing, testing, and delivery of our products. Our focused engineering areas of expertise include:

  • Custom battery pack design
  • Battery management system (BMS) design- We offer both hardware BMS and Smart BMS with I2C, SMBus, RS485, RS232, and CANBUS communication protocol.
  • Housing design- We offer shrink wrap or custom housing designed specifically for your custom lithium battery pack, including tooling service.

Our Efficient Service

CMB offers a user-friendly experience for clients in need of custom battery packs. Our sales representatives walk our customers through every step of the customization journey, and our dedicated international sales team prevents communication barriers for our international clients in order to ensure a smooth and efficient process for all.

Our Quality Control Strategy

CMB prioritizes the quality of battery pack manufacturing, supervised by co-founder Max Lee, implementing ISO 9001:2018, the latest version of the international standard that specifies requirements for a quality management system. Through this approach, all departments are involved, ensuring adherence to industry standards and customer expectations.

We have strict control of our supply chain, manufacturing process, and quality management. Additionally, each battery pack assembly uses a unique tool to boost production safety, dimension, and insulation. A digital monitoring system tracks each custom li-ion battery pack while allowing for improvement of battery workmanship and quality.

Custom Battery Pack Assemblies FAQ

Why should I choose/trust CMB?

With more than 15 years of experience providing custom battery pack solutions, we’ve perfected the design and production of high-quality batteries that suit our customers’ needs. To ensure we’re providing the best products for our clients, we utilize the ISO 9001:2015 quality management system, the latest version of the international standard that specifies requirements for a quality management system. Our production system is efficient, and CMB’s talented and devoted staff are invested not only in our customers but in one another.

Is CMB a manufacturer or trader?

We are a one-stop shop for custom battery pack manufacturing with more than 15 years of experience. We specialize in designing and producing custom battery pack solutions for a range of industrial applications.

What is the lead time for a custom battery pack?

For a standard custom battery pack, you can expect the development, production, and delivery process to take 25-30 business days from beginning to end. If you have more complex technological requirements for your battery pack, that timeline may be extended.

What brand of cells does CMB use in its battery packs?

In our products, we use cells from Panasonic, Samsung, LG, and other well-known Chinese brands. The most important process is determining the right cells for each customer’s unique battery pack needs, and our research and development team is well-equipped to make those determinations.

What is the CMB customization process like?

Our process begins when a customer submits their initial request to CMB. From that request, the CMB team determines the best battery pack option(s) for that customer’s needs. Next, we provide an invoice detailing the pricing, the client makes an initial payment, and we produce and deliver a sample to the client to be tested. The client provides feedback on the sample, we make any necessary modifications to the product based on that feedback, and the client then places their bulk order. We get to work producing and delivering the client’s full order, and once all is said and done, we ensure our customers are 100% satisfied with their CMB products.

Do CMB batteries have UN38.3 certification?

To obtain UN38.8 certification, lithium batteries must undergo a rigorous series of tests performed by an approved independent testing laboratory. Because all of our batteries are custom-made for each order, our products do not have current UN38.3 certification. That being said, we can help you through the process of getting your custom batteries certified.

What insurance does CMB have in place in case a battery catches fire?

CMB is 100% responsible for the international insurance of its battery packs. The end-user can make a claim with CMB in the unlikely case that a battery catches fire.

Can you print our logo on a CMB battery?

Absolutely. We utilize silk screen printing to add custom logos to our battery packs. Simply provide us with your clear logo file.
