The 1-Cell 18650 Battery Holder is designed for projects that use a single 18650 rechargeable lithium-ion battery as a power source.

Instead of connecting wires directly to a battery cell, the holder provides a dedicated mechanical housing for the battery along with wire leads for connecting the cell to a suitable circuit.

A single 18650 Li-ion cell typically provides a 3.7V nominal voltage, making this holder useful for portable electronics, robotics, IoT prototypes, and other battery-powered projects designed for a single-cell Li-ion supply.

The removable battery design also makes it convenient for educational projects where students may need to install, remove, or replace the battery during testing and experimentation.

Battery not included unless specifically stated in the product package.

Important Notes

• Designed for one 18650 rechargeable Li-ion cell.
• The holder itself does not regulate or convert the battery voltage.
• A single Li-ion cell has a nominal voltage of approximately 3.7V, but its actual voltage changes depending on charge state.
• Ensure the connected circuit is compatible with the battery voltage.
• Observe correct positive and negative polarity when connecting the holder.
• Use an appropriate Li-ion charger for the battery.
• Do not attempt to charge the battery through the holder unless the connected charging circuit is specifically designed for Li-ion charging.
• Do not use damaged, swollen, leaking, or otherwise compromised batteries.
• Battery not included.

Why Choose It?

The 1-Cell 18650 Battery Holder with Wire Leads provides a simple and convenient way to integrate a removable 18650 Li-ion battery into electronics, robotics, IoT, and STEM projects.

It eliminates the need to solder wires directly to the battery cell and makes battery replacement easier during prototyping and classroom activities.
