Lithium Battery Power Level LED Indicator Measurement Module


Main Features:
● Power dissipation: single lighting display: 4mA, strip display all lighting: 42mA
● Measuring range: universal 2.4 - 20V battery
● Display type: multi-light strip display or single light display
● PCB size: 45 x 14mm
● Max voltage: 20V AC
● Adjustable power display range, set up according to the line curve of battery: single lithium 1S ( 4.2V ) - 4S ( 16.8V ), lead–acid 6 - 12V, nickel-cadmium 3.6 - 18V, Ni-MH battery 3.6V - 18V
● Suitable for lithium battery, lead–acid battery and other batteries which need power display

Various Batteries Display Voltage Range Adjustment Form:
● Single lithium battery voltage is 3V when discharge off and 4.2V after charging:
1S / 3V ( the first light ) to 4.2V ( the tenth light )
2S / 6V ( the first light ) to 8.4V ( the tenth light )
3S / 9V ( the first light ) to 12.6V ( the tenth light )
4S / 12V ( the first light ) to 16.8V ( the tenth light )
Other series voltage on the basis of this to calculate
● Lead–acid battery ( universal 6V or 12V ):
6V / 4.8V ( the first red light ) to 6.75V ( the tenth light )
12V / 9.6V ( the first red light ) to 13.5V ( the tenth light )
● This module is designed according to the standard of above batteries. It can accurately reflect the power of battery to observe the using status of battery

Adjustment Method:
● Equipment: an adjustable stabilized voltage supply, a flat head screwdriver
● Take the single lithium 3.7V battery for example ( discharge 3V / fully charged 4.2V ): 1. Adjust the voltage of power supply to the high 4.2V then connecting the module. You will see two results: no one lighting or all / several LEDs lighting. Adjust slowly the 503 ( 50k ) potentiometer of module until all LEDs lighting ( remove clockwise for all lighting and anticlockwise for no one lighting or several LEDs lighting. 2. Adjust the voltage of power supply to the low 3V. Adjust slowly the 503 ( 50k ) potentiometer of module until 1 LED lighting ( remove clockwise for no one lighting and anticlockwise for all lighting or several LEDs lighting. 3. Repeat the first and the second step patiently
● Note: red is for positive pole and black is for negative pole. Please use antistatic welding table when welding or adopt power over heat welding
