Our battery boxes are engineered to deliver the perfect balance of lightweight strength, waterproof durability, and thermal stability, ensuring your ride performs at its peak—every time.
Why Us Customized Carbon Fiber Battery Boxes?
Applications
eFoil Battery Enclosures
Designed for the unique demands of hydrofoil boards, our eFoil battery boxes are engineered to keep weight low and perfectly balanced to enhance stability and maneuverability on the water. They feature streamlined shapes to reduce drag, impact-resistant construction to withstand wipeouts, and precision sealing for total waterproof protection.
Electric Surfboard Battery Boxes
Built for high-speed water sports, our electric surfboard enclosures deliver maximum power capacity while maintaining a slim, hydrodynamic profile. The robust carbon fiber structure resists flex and vibration, ensuring consistent electrical connections and optimal performance in rough conditions.
Our OEM Battery Box Projects
Over the years, Unity Sports has partnered with leading surfing & marine sports manufacturer to deliver custom carbon fiber battery enclosures tailored to their specific board designs and performance goals. Here are some examples of our OEM projects

Our Manufacturing Advantages
Full In-House Production
Every step of production happens under one roof at Unity Sports—nothing is outsourced. We control the entire process, starting from weaving our own carbon fiber fabrics, to precision layup, core material CNC carving, autoclave or compression molding, hand finishing and sanding, and premium coating/painting. This complete vertical integration ensures consistent quality, faster lead times, and full confidentiality for OEM clients.
Marine-Grade Quality Standards
All battery enclosures are built to withstand the harshest marine environments. Our designs are rigorously tested for waterproof sealing, impact resistance, UV protection, and saltwater corrosion resistance, ensuring long-lasting performance even in demanding conditions.
Strict Quality Control (QC) System
From raw materials to final inspection, our QC process is embedded at every stage. We conduct dimensional checks, adhesion tests, pressure and leak tests, and cosmetic inspections before any product leaves our facility.
Fast Tooling & Sampling
Thanks to our fully equipped factory, we can deliver mold tooling within 14–21 days, and produce custom prototypes within 14–21 days after tooling is completed. This speed allows our clients to move from concept to market faster than competitors.
Flexible Customization
We adapt every design to your needs—whether it’s size, shape, mounting system, waterproof level, or surface finish (matte, gloss, tinted carbon). Our engineering team works closely with your R&D team to ensure perfect fit and performance integration.
