The 1-Cell 18650 Li-ion Battery Case Holder securely holds a single 18650 rechargeable lithium-ion cell and provides convenient electrical contacts for connecting the battery to electronic circuits and DIY projects.

Full Description

The Battery Case Holder for 1 Li-ion Battery is a practical mounting solution designed to securely hold one standard 18650 lithium-ion battery in electronic projects and battery-powered devices.

The holder uses metal battery contacts to provide a convenient electrical connection without requiring wires to be soldered directly to the battery cell. Depending on the specific version, it may include pre-attached red and black wires for quick connection or PCB-mount terminals for direct integration with electronic boards.

When used with a standard 18650 cell rated at 3.6–3.7V nominal, the holder provides the battery's raw voltage to the connected circuit. The holder itself is a passive mechanical component and normally does not include battery charging or protection circuitry.
