Description
Battery capacity indicator kit is designed to work with 3,7V and 12V lithium batteries. It is equipped with a 10-segment LED display that shows the battery status in real time. The indicator module measures the remaining capacity of the battery and displays it through LEDs. This makes it easy to see how much battery charge is left and when it is time to charge the battery. It comes as a DIY kit that contains all the necessary components, including the LED display, printed circuit board and resistors.
Easy kit to learn soldering. The print on the pcb shows where the components should go. Longest legs on the components is the + and the short leg the -.
Please note: Must be set with an adjustable lab power supply.
– 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 analog voltage, and 10 LED display, display dot mode LED lights 10 one, or in a stripe pattern individually lit LED
– Display Description: shows 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 display for one light, only light, more power, single-phase power of 4mA, all bright 42mA.
– Suitable for lithium batteries, lead acid batteries and other power batteries
– Power adjustable display range for the battery discharge curve of a scientific institution, direct support: single lithium 1S (4.2V) ~ 4S (16.8V), lead acid 6V ~ 12V, NiMH 3.6V ~ 18V, nickel cadmium batteries 3.6V ~ 18V
Battery capacity indicator kit specifications:
– Power: bar display full brightness 42ma, single light shows 4ma
– Measuring range: the battery in the ordinary 2.4-20v
– Dimensions of printed circuit board: 45 x 14 mm
