A press of the button on the front of this little Charge Level Indicator shows the battery charge in 5 steps.

It is designed for a single lithium cell 3.7V and shows voltages between 3.3V (empty) to 4.2V (full).

The wires of the Charge Level Indicator connect directly to the [+] and [-] poles of the lithium cell.

The standby current drawn by the module, when the display is not active, is just about some microampere and will not drain your lithium cell.

Dimensions: 60 x 15.5 x 3 mm
