As a China-based manufacturer located in Shanghai, Lingyufab leverages the region's robust supply chain and skilled workforce to produce high-quality battery enclosures at competitive prices. We adhere to ISO 9001:2015, ISO 14001, and hold TÜV CE certification. Our in-house production eliminates outsourcing costs, delivering 15 to 20 percent cost savings to customers. We support 1-piece samples, 100-piece pilot runs, and high-volume mass production with monthly output exceeding 8000 units.
Our battery enclosures are engineered to precise specifications. Materials include aluminum 5052 and 6061, carbon steel, and stainless steel. Thickness ranges from 1.0mm to 5.0mm depending on load and environmental requirements. Dimensional tolerances are held to plus or minus 0.05mm for critical features. Standard features include gasketed sealing for environmental protection, thermal management provisions, cable entry ports with sealing glands, and mounting brackets. Surface finishing options include powder coating with any RAL color, anodizing, and fire-resistant coatings available upon request. IP66 and NEMA 4 rated protection available. Every batch is backed by Mill Test Certificates ensuring full material traceability.
Lingyufab specializes in producing custom battery enclosure parts including residential energy storage enclosures for home battery systems, commercial battery cabinets for large-scale storage, EV battery trays for electric vehicle applications, telecom backup battery housings for base stations, and UPS battery enclosures for critical power protection. Each part is tailored to your battery configuration and environmental requirements, with provisions for thermal management, cable entry, and mounting. Our engineering team provides upfront technical support, including design optimization, thermal analysis, and cost-reduction recommendations. We support reverse engineering services. If you have a physical sample without drawings, we can 3D scan, model, and generate production-ready engineering prints. Whether you need a single prototype or thousands of units, we deliver consistent quality with zero MOQ for prototyping stages.
What truly sets Lingyufab apart is our ability to integrate the full spectrum of sheet metal processes, including laser cutting, CNC bending, welding, assembly, powder coating, and surface treatment, into a seamless manufacturing workflow for battery enclosures. Rather than outsourcing individual steps to multiple vendors, we manage everything in-house, ensuring tighter quality control, faster lead times, and consistent communication throughout the entire production cycle. With our in-house fastener manufacturing, we can pre-install grounding studs, mounting brackets, and sealing hardware directly into your enclosures, eliminating external sourcing and reducing assembly time on your end. The result is a streamlined, cost-effective solution that performs reliably in the field.
Battery Enclosures offer high structural strength with robust sealing and thermal management features. Materials include aluminum alloys for lightweight thermal conductivity and steel with powder coating for structural protection. Standard features include sealed enclosures with gasketed covers, thermal management provisions including ventilation and heat dissipation, cable entry ports with sealing glands, and mounting provisions for secure installation. Surface finishes include powder coating with RAL color options, stainless steel, and galvanized steel. Fire-resistant coatings available upon request. Full material traceability with Mill Test Certificates MTC for every batch.


Our battery enclosures are widely deployed in energy storage systems for residential and commercial battery banks, electric vehicles for traction battery protection, renewable energy for solar and wind storage integration, backup power systems for UPS and emergency power, and telecommunications for base station backup battery housing. They protect batteries from mechanical damage, moisture, dust, and thermal extremes, ensuring safe and reliable energy storage operation. Lingyufab supports 1-piece prototyping, 100-piece pilot runs, and high-volume mass production with monthly delivery exceeding 8000 units.
A battery enclosure is a protective metal housing fabricated from metal sheets through processes including laser cutting, CNC bending, welding, and powder coating. It is designed to safely contain and protect battery packs, modules, or cells in energy storage systems, electric vehicles, and backup power applications. At Lingyufab, we manufacture enclosures strictly to customer 2D prints in PDF, DWG, and DXF formats and 3D CAD models in STEP, IGES, and SolidWorks formats, ensuring 100 percent build-to-print execution.

These enclosures are deployed in energy storage systems for residential and commercial battery banks, electric vehicles for traction battery protection, renewable energy for solar and wind storage integration, backup power systems for UPS and emergency power, and telecommunications for base station backup battery housing. They protect batteries from mechanical damage, moisture, dust, and thermal extremes, ensuring safe and reliable energy storage operation. Lingyufab serves OEM clients across energy storage, automotive, renewable energy, and telecom sectors.
When integrating a battery enclosure into an assembly, consider thermal management requirements for battery operation, cable entry and routing, mounting orientation for structural integrity, and accessibility for maintenance. Ensure proper sealing to maintain environmental protection. Recommended design practices include maintaining minimum flange length of at least 4 times material thickness, using consistent bend radii, and adding bend relief notches at corners to prevent tearing. Our engineering team provides assembly drawings, thermal analysis, and installation recommendations to streamline your final integration.
