3-Slot 18650 Battery Holder Case

The 3-slot 18650 battery holder case is designed to hold three 18650 rechargeable lithium batteries for DIY electronics, robotics, LED, and portable power projects. It is suitable for users who want to build a higher-capacity or higher-voltage battery-powered project, depending on the wiring and circuit design.

This holder is useful for Arduino power systems, robotics projects, solar prototypes, LED lighting, wireless electronics, and school STEM projects. It keeps the batteries arranged neatly and makes battery replacement easier during testing, repair, or project development.

For rechargeable lithium battery pack projects, use the correct BMS module, charger, and protection circuit. For 3-cell lithium pack projects, a suitable 3S BMS and 12.6V lithium charger may be required depending on the connection.
