## Description

We strive to provide you with the highest quality product and the best If you're not entirely satisfied, please just feel free to contact us at any time.Features:- 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.Parameter:Power: bar display full brightness 42ma, single light shows 4maMeasuring range: the battery inside the common 2.4-20vColor: red, green, blue, Display: Multi-light bar display or a single light dot displaypcb board size: 45 x 14 mmDisplay 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 displayA 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 Batteries6V 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 t

## Features

- Make sure this fits by entering your model number.
- - 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
- - 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
