Thank you and have a nice day!Description:This is a DIY kits,need buyer to assemble it.
Power display is to take some voltage, perform simulations show the percentage of segments, such as 3.7V lithium battery, take the lower voltage 3V, the upper limit of 4.2V, 4.2-3 = 1.2V, the voltage difference between the lower limit of 1.2V, is the battery Analog .
LM3914 can accurately detect an analog voltage, 10 LED display, either Multi-light bar display or a single light dot display.
10 LED Displays the battery voltage,bar display full brightness 42mA, single light shows 4mA.
Support: single lithium 1S (4.2V) ~ 4S (16.8V), lead acid 6V ~ 12V, NiMH 3.6V ~ 18V, nickel-cadmium batteries 3.6V ~ 18V.Specification:Power: bar display full brightness 42mA, single light shows 4mA
Measuring range: the battery inside the common 2.4-20v
Display: Multi-light bar display or a single light dot display
Size：45x14 mm / 1.77x0.55 inchPackage Includes:1 Piece modules
6 Pieces accessories
Note:To adjust their voltage, according to the method of adjusting the order, to emphasize high-end, then adjust the low end.Red then positive, then negative black, must not be reversed, this module is the maximum limit voltage DC 20V, please use anti-static welding or station pull electric heat welding.
Please allow slightly difference due to manual measurement.
