OEM/ODM Lithium Battery Customization Services
With over a decade of experience in industrial lithium batteries, EvFrey provides comprehensive OEM/ODM customization services covering the entire product lifecycle.
From requirement analysis, solution design, and component selection to manufacturing, quality inspection, and compliant packaging, we professionally manage every stage of the project to deliver customized lithium battery solutions tailored to each customer’s application, product positioning, and target market.
01
Requirement Consultation
Every successful OEM/ODM project begins with a thorough understanding of the customer’s requirements.
At the start of the project, the EvFrey team works closely with you to understand your product concept, technical specifications, application scenarios, operating environment, and market positioning, establishing a clear foundation for solution development.
Backed by extensive experience in lithium battery applications and project development, we can support you even if you only have an initial concept. Our team provides professional guidance throughout the project, helping you define your requirements, refine your product concept, and develop a practical custom solution.
02
Professional Engineering Design
Professional engineering design is fundamental to battery performance, safety, and user experience.
Using professional computer-aided design software, the EvFrey engineering team designs and optimizes battery modules, battery management systems (BMS), connection terminals, enclosures, and other functional components to ensure the solution meets real-world application requirements.
Optional features include:
LCD state-of-charge display
Bluetooth monitoring
Integrated heating
Modular design and counterweight solutions
Other customized hardware and software features
Once the design is completed, we can provide 2D engineering drawings or 3D renderings, allowing you to review the product structure and appearance and approve the final solution before production.
03
Component Sourcing
Consistent and reliable product quality begins with the careful selection of battery cells and every component.
Supported by a mature supply chain management system, EvFrey selects and sources battery cells, BMS units, connectors, structural parts, and other critical components in accordance with project specifications and quality standards, ensuring that each design can be successfully transformed into a high-quality product.
Through long-term partnerships with qualified suppliers, we strengthen quality control at the source and provide a solid foundation for battery safety, reliability, and consistency.

We allocate production capacity based on order volume, product complexity, and delivery schedules, balancing quality and efficiency to help keep your project on track.
05
Rigorous Testing and Inspection
Rigorous quality inspection is implemented at every stage, from incoming materials to finished-product shipment.
With established quality management procedures and professional testing equipment, EvFrey conducts multiple inspections of incoming materials, critical components, production processes, and finished products to ensure that every batch meets the specified technical and quality requirements before delivery.
Key inspection items include:
Charge and discharge function testing
Electrical performance and safety protection checks
Appearance and assembly quality inspection
Comprehensive pre-shipment inspection
Through systematic testing and quality control, we are committed to delivering lithium battery products with consistent performance and dependable quality.
06
Compliant and Secure Packaging
Professional and compliant packaging is essential to the safe transportation of lithium batteries.
EvFrey develops packaging solutions based on the product type, mode of transportation, and destination requirements, following applicable lithium battery transport regulations. Cartons or plywood cases that meet relevant requirements may be used to protect products during storage, handling, and transportation.
Where applicable, packaging and labeling are prepared in accordance with relevant transport requirements to support the safe and compliant delivery of products to the customer’s designated destination.
