• 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 , 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), 6V ~ 12V, NiMH 3.6V ~ 18V, nickel-cadmium batteries 3.6V ~ 18V.
