lm3914 battery capacity indicator module

lm3914 battery capacity indicator module led power level tester display board
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

Parameter:

Power: bar display full brightness 42ma, single light shows 4ma
Measuring range: the battery inside the common 2.4-20v
Color: red, green, blue,
Display: Multi-light bar display or a single light dot display
pcb board size: 45 x 14 mm
Display Mode A / P: full brightness linear / single lamp lattice mode switch, the default is a linear model, the board set aside a switch pad, even with soldering pads can be turned into full light linear mode, no welding is the point like single light display

A variety of high and low voltage battery display range adjustment:

1. Lithium battery:
After the completion of a single lithium battery discharge voltage is 3V, when fully charged 4.2V;
1S correspond to 3V (first light) to 4.2V (tenth lights);
2S corresponds to 6V (first light) to 8.4V (tenth lights);
3S correspond to 9V (first light) to 12.6V (tenth lights);
4S correspond to 12V (first light) to 16.8V (tenth lights);
Other series voltage and so on.

2. Lead Acid Batteries
6V or 12V lead-acid battery is generally:
6V corresponds to 4.8V (first red light) to 6.75V (tenth lights);
12V corresponds to 9.6V (first red light) to 13.5V (tenth lights);
The module according to the above standard battery discharge range design, can accurately reflect the battery, so that users can readily observe the status of the battery.
