The 1 Slot 18650 lithium battery holder provides a removable mounting solution for a single 18650 Li-Ion cell, the cell slides in, spring contacts hold it in place, and 100mm open wire leads exit the holder for connection to the project circuit. The cell can be removed and replaced at any time without touching the circuit wiring, which is the key advantage over soldering or spot-welding an 18650 cell directly. Plastic body construction keeps the holder lightweight at 75 x 18 x 20 mm close enough to the 18650 cell’s own dimensions to fit inside enclosures without adding significant bulk around the cell.
The 18650 battery holder 100mm wire leads provide enough length to reach from the holder’s mounting position to the circuit’s power input pads or connector, with the open wire ends giving the freedom to solder directly, crimp a JST connector or attach any terminal format the project requires. The single battery holder suits running from one 18650 cell where cell replacement between sessions is preferred over a fixed welded pack. This holder is available on StemVolt and working on 18650 cell-powered project and portable power designs.
