The 18650 Battery Holder is a plastic holder used to hold 18650 format lithium ion batteries on the circuit and provide electrical connection. It is available in single compartment, 2-cell and 4-cell models; the 2-cell model can be used to obtain 7.4V with series connection, the 4-cell model can be used to obtain 14.8V with series connection or higher capacity with parallel connection. Solder tip or cable output types are available. It is an indispensable component for building portable power systems, used in combination with the TP4056 charging module and regulator modules such as the MT3608/LM2596.
