Battery Raw Material: Zero-Weld Metal Box for Battery Pack Lithium Ion Battery Box

We’re offering custom Battery Pack Cases (48v/60v/72v, 20ah-100ah) for Lifepo4 & Lithium Ion batteries, Crafted from high-quality metal, it also offers reliable structural support and stable heat dissipation, adapting to various battery pack configurations for scenarios like electric vehicles, energy storage systems, and portable electronics. It’s an ideal choice for buyers seeking long-lasting, low-maintenance battery packaging solutions.

• As a key battery raw material and specialized metal box for battery packs, this product gains competitive edge from its exclusive zero-weld design—achieved via integrated stretch molding. The seamless structure eliminates welding-induced weak points, boosting 30% higher durability and airtightness compared to traditional welded boxes. It effectively resists external impacts, moisture, and dust, fully protecting internal battery cells from damage and extending overall battery pack lifespan.

  Made of high-grade metal, it also ensures stable structural support and efficient heat dissipation, 适配 (adapting to) 48V/60V/72V battery packs for electric bikes, golf carts, energy storage systems, and portable electronics. We support customization (size, thickness, surface treatment) and offer low MOQ, with samples available for testing. Certifications like CE and RoHS are provided to meet global market standards—ideal for buyers seeking reliable, cost-effective battery packaging solutions.
