Universal Battery Compartment Shells (AA/AAA) – The Foundation for Your DIY Projects

Whether you are designing a new toy, building an electric model, or replacing a broken battery housing, these robust battery shells provide the perfect flexible solution for your power supply needs.

Modular & Adaptable

These shells are available in three different sizes (1-slot, 2-slot, and 3-slot) and are optimized for standard AA (Mignon) or AAA (Micro) cells. Designed with the maker in mind, they are compatible with standard battery contact sets (easily sourced from platforms like AliExpress), allowing you to transform a simple housing into a fully functional power source in seconds.

Two Convenient Mounting Options

The shells are engineered for seamless integration into your project:

• Screw Mounting: Use the integrated countersunk boreholes to fix the box flush and securely at the desired position.
• Adhesive Mounting: Thanks to the flat underside, the shells can also be easily attached using double-sided mounting tape or hot glue—perfect when drilling isn't an option.

Key Features at a Glance:

• Versatile Use: Ideal for RC model making, prototyping, or custom toy manufacturing.
• DIY-Friendly: Optimized for easy insertion of common spring-and-plate contact sets.
• Durable Design: Made from high-quality white plastic (3D-printed), ensuring batteries stay securely in place even in high-vibration environments.
• Customizable Wiring: Once the contacts are inserted, they can be easily soldered or fitted with crimp connectors.
