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

Q

No where do I see that this is an unassembled untested kit? Am I the only one that received a bag of parts with no data sheet, no assembly layout or schematics.

Hello Jon,

   


Supplementary explanation Display mode A/P: Full-bright linear/single-lamp mode switching, the default is linear mode, the switch pad is reserved on the board, and the solder can be connected to the pad to become a full-bright linear mode without soldering. Is the single-lamp display mode


Note: Red is connected to the positive pole, black is connected to the negative pole, and can not be reversed. The reverse limit is directly discarded. The maximum limit voltage of this module is DC 20V. Please use anti-s
