Global Manufacturing Footprint

Epec Engineered Technologies has made significant investments to build a world-class, U.S.-based manufacturing operation while also developing a mature global manufacturing footprint. This combined model supports complex battery pack programs from initial concept through full production. By integrating in-house engineering, tooling, and testing with qualified lower-cost manufacturing regions, Epec delivers consistent quality and reliability across all production locations.

Domestic Manufacturing

Epec’s domestic manufacturing operations are centered in New Bedford, Massachusetts, approximately 40 miles south of Boston. This state-of-the-art, 55,000 square foot design and manufacturing facility was custom built and occupied in 2018 after the company outgrew its previous location, which had supported operations for 50 years.

The facility houses Epec’s full design engineering team, a dedicated prototype laboratory, and an ISO-9001:2018 certified manufacturing operation. Due to the nature of the products produced, the facility is routinely audited by UL, the FDA for medical device battery processes, and the U.S. Department of Transportation to ensure compliance with transportation and shipping regulations.

Asia Manufacturing

Epec supports global battery pack production through manufacturing locations in China, India, Malaysia, and Taiwan, in addition to its U.S. facility. U.S.-based engineers and product managers work directly with customers to finalize designs and documentation, which are then transferred to manufacturing partners in lower-cost regions when appropriate.

In many cases, Epec designs battery packs using name-brand cells from manufacturers such as Panasonic, Samsung, LG, FDK, and Molicel, with final production completed in Asia. Epec also maintains access to a wide range of additional cell manufacturers, allowing flexibility in performance, cost, quality, and reliability options based on customer requirements.

Epec operates two manufacturing facilities in the Shenzhen region, providing substantial capacity for alkaline, lithium, and NiMH battery pack production. All manufacturing and test processes are developed by Epec, and company employees are present on site daily to ensure work instructions are followed precisely.

Supply Chain and Regulatory Management

Epec maintains established relationships with regulatory agencies and test laboratories in both the United States and Asia. These relationships support ongoing compliance across all stages of battery pack production, including annual recertification requirements, documentation updates for component changes, and strict adherence to air shipping regulations for lithium batteries.

Regulatory management is treated as a critical responsibility, as even minor errors can result in suspended authorization to ship lithium batteries. Epec manages detailed logistics requirements on behalf of customers, including advance sample submissions and recurring approvals required for specific battery chemistries, ensuring uninterrupted global shipments.

Production Planning

When rapid timelines are required, Epec has the capability to move quickly through the full development cycle, from concept to production. Once production is established, customers gain access to inventory management services that include storage of custom battery packs in climate-controlled warehouses.

This approach allows customers to benefit from the economics of low-cost manufacturing regions while maintaining readily available inventory. Battery packs stored in our warehouse can be shipped to customers in as little as 24 hours, supporting both forecasted demand and urgent requirements.

Reliable Battery Pack Manufacturing Solutions

Epec’s objective is to make global battery pack management as straightforward as possible. The company understands that many customers have experienced challenges with suppliers that prioritize low-cost manufacturing without transparency or delivery reliability. With more than 20 years of battery pack manufacturing experience in Asia, a long-term regional investment, and more than 30 employees supporting these operations, Epec provides a proven and dependable global manufacturing solution.
