Red Lead Acid Battery Capacity Indicator Module, LM3914 Battery Power Tester

Red Lead Acid Battery Capacity Indicator Module LM3914 Battery Power Tester

Red Lead Acid Battery Capacity Indicator Module, LM3914 Battery Power Tester

Features: - 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 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 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. Adjustment methods: Equipment needed: an adjustable power supply, precision accuracy of the decisions of the panel display.
