The Story of Battery Box Factory
From Prototype to Global Supply
Founded by a team of engineers passionate about power system safety, Battery Box Factory began with a simple goal — to create durable plastic enclosures that could withstand real-world abuse. Over the years, we’ve evolved from a small tooling workshop into a global OEM and ODM supplier, providing custom battery housings for energy storage brands, electric mobility startups, and marine equipment manufacturers around the world.
We combine precision injection molding, material science, and industrial design expertise to create enclosures that meet modern expectations for both strength and style. Whether you need a single housing model for your e-bike brand or bulk containers for solar battery installations, we have the experience and tooling capability to deliver consistently high quality.
Engineering Strength You Can Rely On
All our products are developed under a strict engineering framework focused on sealing, structure, and usability. Every box is made from high-impact polypropylene or ABS material, providing UV resistance, corrosion resistance, and mechanical strength even in marine or off-grid conditions.
- IP65–IP67 Waterproofing: Silicone gasket seals and precision-fit lids keep moisture out.
- Customizable Interiors: Space for BMS, fuse holders, terminals, and wiring channels.
- Modular Design: Compatible with lithium and lead-acid battery configurations.
- OEM Branding: Logo engraving, custom colors, and packaging options available.
We don’t just sell boxes — we engineer complete power protection solutions that help our clients build better products.
