Choose high-quality materials to ensure product qualityProduct ParametersMaximum withstand voltage: 16V ± 10%Voltage range: 3~12.8VBattery capacity: unlimitedBattery display: 0%~100% (every 10% grid)Detection accuracy: 100% ± 10%Average working current: about 7mA ± 10%Module size: 18.1mm * 8mm * 6.1mm (length * width * thickness, there may be slight errors in manual measurement, please refer to the actual product)Output control: NoneReverse connection protection: None (positive and negative poles cannot be reversed, otherwise the module will be damaged)Product IntroductionThis product is suitable for percentage power indication of 1/2/3/4 DC 3.2V lithium iron batteries; Due to the high requirements of the iron lithium battery curve for the detection value of the electricity meter, it can currently only display 10% of the grid (such as 0% -10% -20%... 100%). This type of electricity meter is divided into four styles: 1S, 2S, 3S, 4S, corresponding to 1 section or parallel 3.2V, 2 sections in series 6.4V, 3 sections in series 9.6V, and 4 sections in series 12.8V, respectivelyPrecautions1. VCC is connected to the positive pole of the battery, GND is connected to the negative pole of the battery, and there are markings on both the front and back of the board2. Power off when wiring, otherwise accidentally touching the pins behind the board may cause a short circuit and burn out the module; After welding, confirm that the positive and negative terminals of the power supply have not touched the pin pads behind the electricity meter before powering on3. There is no reverse connection protection. Connecting the positive and negative poles incorrectly can burn out the module. It is recommended to confirm the positive and negative poles before wiringPacking ListBattery display module * 1
