4 Power Indicator Battery Detection Module
A Power Indicator Battery Detection Module is a gadget that detects the charge level in a battery and displays the remaining power level to the user.
It often contains a voltage divider circuit that can convert the battery voltage to a level that a microcontroller or other device can read, as well as an indicator circuit that may display the remaining power level using LEDs or other visual means.
The Power Indication Battery Detection Sensor Module you indicated most likely has four LEDs or other indicator lights to indicate different degrees of remaining power, such as a green LED for full power, a yellow LED for medium power, and a red LED for low power. Onboard high precision voltage detection chip and power supply voltage chip.Four onboard battery indicator light-emitting diodes (leds).
Three kinds of color display, red, yellow, green, representing 20%, 50%, 80%, 100% of the battery. Set aside all the batteries testing interface and the two positioning hole. By Removing the LEDs and extending their connections to arduino, this module can also be used with all arduino boards. PCB Size: 22.2(mm)x17.2.(mm)

1. How does a 4 power indicator battery detection module works?
- Connect the battery for charge testing to the circuit first. When connected, a 1N4733A 5.1V, 1W Zener diode is used to regulate the voltage, along with a series resistor R1 to control the current flow through the zener. As a result, we obtained a regulated 5.1V output voltage from the battery. Connect the battery for charge testing to the circuit first.

2. What are Battery charge indicator?
- Battery charge indicator circuits are extremely useful modules for making the best use of Lipo batteries. These types of indicators typically measure the voltage in the battery and display the charge status by turning on any appropriate LEDs.
