Custom Sheet‑Metal Lithium‑ion Battery Fireproof & Explosion‑Proof Safety Box

Our portable metal lithium‑ion battery fireproof / explosion‑proof boxes are manufactured via sheet‑metal laser cutting, precision bending and laser welding. Designed to contain thermal‑runaway risks for lithium‑ion batteries during lab testing, transit and field deployment. Besides battery safety housing, this same sheet‑metal structure can also be custom‑modified into metal tool box, energy storage box and general‑purpose portable carry case for multiple industrial uses. This is a fully custom OEM & ODM product; ready‑made standard units are not in stock.

6. FAQ

Q1: What is a lithium‑ion battery fireproof box? 

A: A lithium‑ion battery fireproof box is a protective enclosure that provides physical isolation for lithium‑ion batteries during storage, handling, charging, testing and other operations. It helps mitigate hazards caused by battery thermal runaway.

Q2: Do you provide OEM and ODM services? 

A: Yes. We offer OEM manufacturing and ODM development services for custom metal battery boxes and other sheet‑metal hardware products.

Q3: Can you supply standard‑size fireproof battery boxes directly from stock? 

A: No. All boxes are custom‑manufactured from client drawings. Reference samples exist for evaluation purpose only.

Q4: Can this box be made as a metal tool box or energy storage box? 

A: Yes. The same sheet‑metal cabinet structure can be re‑customized into tool box, energy storage box or portable carry case by adjusting internal layout, cutouts and accessories.

Q5: Can I customize logo, inner fire‑resistant material and internal dividers? 

A: Yes. We support custom logo engraving or printing on outer shell. Fire‑resistant lining material, EVA foam and separation dividers can all be modified to meet your project needs.

Q6: What information do I need to provide for an accurate quote? 

A: Please share 2D/3D drawing, outer dimension requirement, preferred material, handle & latch configuration and order quantity. Let us know your end‑use: battery, tool storage or other purpose, also specify requirements for logo, inner lining and dividers if you have.

Q7: Do you support small‑batch prototype orders? 

A: Yes. We handle both prototype small runs and large‑volume mass production.

7. Request Custom Quotation

If you are sourcing custom lithium‑ion battery fireproof explosion‑proof box, metal tool box or energy‑storage portable case, submit your drawing, dimension specs or reference photos. Please also note your requirements for logo, inner fire‑resistant material or dividers if needed. Our engineering team will assess your project and send a formal offer.
