Aideepen DC 3.7-4.2V Power Display Module 1S Ternary Lithium Battery Electricity Meter Indicator Led Light Mini

Parameter:Product name: lithium battery power display moduleInput voltage: DC 2-6.5V (single lithium battery)Operating current: less than 1mA (negligible, chip power consumption <10uA, the rest of the power consumption from the LED)Brightness adjustment: modify 1K resistor can adjust the brightness (value range 100Ω-20K)Applicable batteries: various types of 3.7V lithium batteries, including 18650, 21700, 32700, etc.Description:The product is suitable for everyone in the DIY with a single lithium battery, the remaining power display, the principle is that the product IC chip through the detection of the input voltage, to determine the remaining battery power, 4 LEDs represent 4 detection points, built-in comparator and feedback loop, to achieve the detection of the 4 voltage points. Through the internal trimming technology, it can ensure the voltage detection accuracy reaches ±1%, built-in 4-way comparator to realize the detection of 4 voltage points, the internal comparator has a reasonable hysteresis, which is convenient to do charging and discharging instructions.Package include:Module x5
