Design and Construction

The holder features a triple-slot design with dedicated positions for three 18650 cells. The ABS housing provides a lightweight and durable structure, while the spring contacts help keep the batteries securely positioned.

Clearly marked positive and negative polarity symbols make it easier to insert the batteries in the correct orientation. The spring-contact design also allows batteries to be installed and removed conveniently.

Working Principle

Each 18650 battery is inserted into its respective slot according to the marked positive (+) and negative (-) polarity. The spring contacts establish electrical contact with the battery terminals and provide connection to the holder’s output terminals.

The three-cell holder can be incorporated into suitable battery-pack configurations according to the requirements of the connected circuit.
