The 2 Slot 18650 lithium battery holder holds two 18650 Li-Ion cells and provides open wire leads for connecting them into a project circuit. The two slots wire in series by default in most dual-slot holder designs connecting positive of one cell to negative of the other producing 7.4V nominal output from two 3.7V cells for 2S. Alternatively, the cells can be wired in parallel through external connections for 3.7V at doubled capacity. Open wire leads gives the freedom to solder directly, crimp a JST connector or attach any terminal format the project requires.
The dual slot holder 18650 plastic body houses both cells side by side with spring contacts at each terminal end, keeping cells secure during project operation without additional fastening. No onboard switch means the output connects directly whenever cells are loaded power switching requires an external switch wired into the circuit. The 18650 battery holder removable cell format allows cells to be swapped between sessions without disturbing the circuit wiring. Available on StemVolt. This holder is working on 2-cell 18650 and dual cell portable power projects.
