Product Description

Features:
– 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 power up
– LM3914 can accurately detect an analog voltage, and 10 LED display, display dot mode LED is lit 10 one, or in a stripe pattern individually lit LED
– Display Description: Displays the battery voltage between the lower limit of 10 files showed that representatives of each of the lights 10% charge displays, on behalf of 10 lights display charge 0% -100% range; you can also change the single light display, is displayed only a light, more power, single-light power 4mA, all bright 42mA.
– Suitable for lithium batteries, lead-acid batteries and other power batteries need to be displayed
– Power adjustable display range for the battery discharge curve of a scientific setting, direct support: single lithium 1S (4.2V) ~ 4S (16.8V), lead acid 6V ~ 12V, NiMH 3.6V ~ 18V, nickel-cadmium batteries 3.6V ~ 18V
