Description

This Battery Holder is ideal for making your own 1S4P (3.7 Volt) Battery Pack, just insert your choice of 18650 Li-on cell and fit a connector, then you have a fully protected 1S4P Battery Pack for your project – with no soldering/welding of cells. 

Please note that after installing (or re-installing) the 18650 cell(s) you will need to connect the pack to a suitable charger of correct voltage to “activate” the Protection Circuit on the PCB otherwise NO pack output will be available – this is a built-in safety feature.
