Aideepen | 1S-4S 3.2V LiFePO4 Battery Power Display Module 3-12.8V Digital Percentage Indicator Board Battery Capacity Indicator Module

Features:1. Specifically designed for lithium iron phosphate batteries, with precise compatibility for 1S–4S configurations2. Percentage-based digital display for an at-a-glance view of battery level3. Ultra-compact module size for easy integration into compact devices4. Low-power operation extends the device’s standby time5. Made with high-quality materials to ensure product reliabilityProduct SpecificationsMaximum voltage: 16V±10%Voltage Range: 3–12.8VBattery Capacity: UnlimitedCharge Display: 0%–100% (10% increments)Measurement Accuracy: 100% ±10%Average Operating Current: Approx. 7mA ±10%Module Dimensions: 18.1mm × 8mm × 6.1mm (L × W × H; manual measurements may have slight discrepancies; actual product dimensions prevail)Output control: NoneReverse polarity protection: None (Do not reverse positive and negative terminals, as this will damage the module)Product OverviewThis product is suitable for displaying the percentage charge of 1, 2, 3, or 4-cell 3.2V LiFePO4 batteries. Due to the demanding nature of LiFePO4 battery discharge curves, the display currently only shows 10% increments (e.g., 0%–10%–20%... . 100%). This battery meter series is available in four models: 1S, 2S, 3S, and 4S, corresponding to 1 cell (3.2V in parallel), 2 cells (6.4V in series), 3 cells (9.6V in series), and 4 cells (12.8V in series), respectively.Precautions1. Connect VCC to the battery positive terminal and GND to the battery negative terminal. Markings are present on both the front and back of the board2. Ensure the power is disconnected before wiring; otherwise, accidentally touching the pins on the back of the board may cause a short circuit and damage the module. After soldering, verify that the power supply’s positive and negative terminals do not touch the pin pads on the back of the battery meter before powering on.3. There is no reverse polarity protection; connecting the positive and negative terminals incorrectly will damage the module. It is recommended to verify the polarity before connecting the wires.Package ContentsBattery Level Display Module *1
