Custom Process

We build dependable batteries designed to meet our customers’ unique specifications. Here’s a look at how we do that.


Any good product starts with its blueprint. Our Chief Technology Officer has extensive experience with and knowledge of a wide array of battery pack technology designs and the cell chemistry needed for optimal and prolonged product performance. Additionally, once a customer has a battery pack design on file, our team of engineers will systematically upgrade the technology each year to ensure every product we produce is of the best and most up-to-date quality.



To ensure our products’ performance surpasses customer expectations, we use top-notch materials from trusted sources. Our cells come from Panasonic, Samsung, LG and other well known Chinese brands. Most of the materials are certified with UL,CE, and ROHS.



CMB’s manufacturing process ensures every CMB battery is stunning from the inside out. Every one of our production workers are trained for more than 3 months before they begin working on any CMB products. Each employee is thoroughly educated on our Battery Management Systems and masters the necessary skills for assembling a perfect custom made battery pack, like spot welding and soldering.


Quality Control

During our production process, we strive for efficiency, but quality is of the utmost importance. Our QC team thoroughly inspects and records every order. We run tests to ensure the battery charge and discharge are up to CMB requirements, and our quality management team adheres to ISO9001:2015 standards.



We offer a number of international shipping options to suit each customer’s needs. If a customer requires a Dangerous Goods Certificate, we will apply for that on their behalf free of charge. Our batteries are packed carefully into pallets. Once an order has shipped, we provide tracking information and update the customer regularly with its progress.
