CAD Design of a Reinforced 18650 Battery Pack

Lavriv Studio — Reliable Power in a Thoughtful Form

This project focused on the development of a reinforced battery pack designed for 18650 lithium-ion cells, intended for use in portable power tools, flashlights, and other autonomous devices.

The primary emphasis was placed on structural durability, user convenience, and the ability to perform instant charging without a docking station.

Concept & Functional Features

The battery pack was designed as a versatile power solution capable of withstanding mechanical loads, vibrations, and intensive daily use.

The design enables direct connection to a charger, significantly increasing mobility and reducing equipment downtime.

CAD Design Process

1. Housing & Structural Geometry

The enclosure was modeled with enhanced rigidity in mind:

– reinforced walls,

– integrated structural ribs,

– optimized transitions and fillets to minimize stress concentration.

2. Parametric 3D Modeling

The model was created using a parametric approach, allowing easy adaptation for different 18650 cell configurations or dimensional changes based on specific application requirements.

3. Electrical Contacts & Locking Mechanism Integration

Dedicated mounting features were designed for contact terminals, locking elements, and guiding rails to ensure:

– reliable electrical connection,

– protection against incorrect insertion,

– quick and secure installation and removal.

4. Manufacturing Preparation

The design was optimized for 3D printing and scalable manufacturing, with careful control of tolerances, wall thicknesses, and functional clearances.

Final models were prepared for export into production-ready formats.

Result

The final outcome is a robust, functional, and universal battery pack ready for integration into a wide range of devices — from power tools to lighting systems.

This project reflects the Lavriv Studio approach to CAD design: combining engineering logic, practicality, and real-world readiness.
