Description
4 × 18650 Lithium-Ion Battery Holder
The 4 × 18650 Battery Holder is designed to hold four compatible 18650 rechargeable lithium-ion batteries for electronics, robotics, and portable power projects. It helps keep the cells organized and provides a convenient mounting solution for battery-powered devices and DIY circuits.
The holder’s output voltage depends on its internal wiring configuration. With four standard 3.6V–3.7V nominal cells connected in series (4S), the pack provides approximately 14.4V–14.8V nominal voltage. With the cells connected in parallel (1S4P), the nominal voltage remains approximately 3.6V–3.7V while the available capacity increases.
Key Features
- Holds four compatible 18650 cylindrical lithium-ion batteries.
- Designed for multi-cell battery projects.
- Helps secure and organize battery cells.
- Suitable for robotics, portable electronics, and DIY power applications.
- Battery insertion and removal depend on the holder design.
- Wiring configuration and output connections may vary by model.

Important Safety Notes
- Batteries are typically sold separately.
- Confirm whether the holder is wired in series, parallel, or supplied without interconnecting wiring.
- Use a suitable battery protection circuit/BMS and a charger matched to the actual cell configuration.
- For four cells in series, use a compatible 4S lithium-ion charger and protection system.
- Use compatible cells with matching chemistry, capacity, and condition.
- Verify polarity and output voltage before connecting the holder to any electronic device.
- The term “LiPo” is often used loosely in listings; standard cylindrical 18650 cells are generally lithium-ion cells. Confirm the actual battery chemistry.
