## Description

Quickly displays the charge level for a 1S lithium cell between 3.3 and 4.2V, with 4 blue bars for 25, 50, 75 and 100% and a red outline when it drops below 25%. It operates at 3.7V DC with low consumption of approximately 5mA, it is compact, 43.5 x 20mm, ideal for portable projects and electronic equipment.
Indicator module for displaying the charging status of a 1S lithium battery, 4.2V
The module indicates the charging status of a lithium cell (Ni-MH cells can also be used if their voltage fits the specifications, both when charged and discharged).
The module displays the charge level through the 4 bars, and when the battery level drops below 25%, only the red frame (battery-shaped) will light up.
