Features:1. Ultra-compact embedded design with mini dimensions for tight spaces2. Built-in 4-channel high-precision comparators and feedback loops within the IC3. Internal comparators feature optimized hysteresis for clear charge/discharge indication4. High voltage detection accuracy (±1% error) supporting 4 voltage points5. Dual red/orange LED display with 4 mini LEDs for prominent power status indicationParameter:Product Name: Mini Battery Indicator ModuleLED Colors: 4 LEDs (1 red, 2/3/4 orange)Voltage:1S Single Cell: DC 3-4.2V2S Dual Series: DC 5.8-8.4V3S Triple Series: DC 8.8-12.6V1S Blackboard:Voltage at 25% charge: 3.0-3.3V, 1 LED litVoltage at 50% charge: 3.3-3.5V, 2 LEDs litVoltage at 75% charge: 3.5-3.8V, 3 LEDs litVoltage at 100% charge: 3.8-4.2V, 4 LEDs lit2S White Board:Voltage at 0% charge: 5.8-6.2V, 1 LED flashingVoltage at 25% charge: 6.2-6.8V, 1 LED steadyVoltage at 50% charge: 6.8-7.3V, 2 LEDs steadyVoltage at 75% charge: 7.3-7.8V, 3 lights steadyVoltage at 100% charge: 7.8-8.4V, 4 lights steady3S Blue Board:Voltage at 0% charge: 8.8-9.4V, 1 light flashingVoltage at 25% charge: 9.4-10.3V, 1 light steadyVoltage at 50% charge: 10.3-11.1V, 2 lights steadyVoltage at 75% charge: 11.1-11.8V, 3 lights steadyVoltage at 100% charge: 11.8-12.6V, 4 lights steadyPrecautions:When using inductive loads such as motors, if burnout occurs, it indicates the need to add a TVS diode or electrolytic capacitor at the input to absorb high-voltage reverse surges. Motor acceleration/deceleration generates high-voltage surges that can damage the module.Package include:Module x1
