Description
3 × 18650 Lithium-Ion Battery Holder
The 3 × 18650 Lithium-Ion Battery Holder is designed to hold three compatible 18650 rechargeable lithium-ion batteries securely in one compact housing. It is suitable for DIY electronics, robotics, portable power projects, and battery-powered devices.
The holder makes it easier to organize and connect multiple cells in a circuit. Depending on the holder’s internal wiring, the batteries may be connected in series or parallel. A three-cell series configuration (3S) provides approximately 10.8V–11.1V nominal voltage, while a parallel configuration (1S3P) retains the nominal voltage of a single cell and increases the available capacity.
Key Features
- Holds three compatible 18650 cylindrical batteries.
- Compact housing for multi-cell battery projects.
- Helps secure batteries and organize connections.
- Suitable for DIY electronics, robotics, and portable devices.
- Battery insertion and replacement depend on the holder design.
- Wiring configuration and output connections may vary by model.
