Lithium Battery Power Display Module (Blue)
The Lithium Battery Power Display Module is a user-friendly and intuitive tool for real-time battery monitoring. It offers a digital visual display to indicate the charge level of various types of batteries including lithium-ion (18650, polymer), nickel-metal hydride, lead-acid, and electric vehicle batteries. This module is ideal for both DIY and industrial applications requiring accurate voltage-based battery level readings.
Package Includes:
- 1 × Lithium Battery Power Display Module
Features:
- Intuitive Digital Display: Displays battery charge using 4 blue LED blocks, offering a clear and visually appealing battery level indicator.
- Wide Compatibility: Suitable for 1S lithium batteries and larger battery packs (nickel-metal hydride, lithium polymer, lead-acid, and electric vehicle batteries).
- Real-Time Monitoring: Instant visual feedback based on real-time voltage detection.
- Low Voltage Alert: All LEDs turn off when voltage drops below 3.3V per cell, indicating the need for charging.
- Easy Setup: Simply connect the display board’s positive and negative terminals to the battery’s respective terminals.
Voltage-Based LED Illumination (Per Cell):
- 1 LED block on: Voltage > N × 3.3V
- 2 LED blocks on: Voltage > N × 3.5V
- 3 LED blocks on: Voltage > N × 3.7V
- 4 LED blocks on (full): Voltage > N × 3.9V
Voltage Measurement Ranges:
- Slot 1: 3V to 4.2V (for 1S batteries)
- Slot 2: 6V to 8.4V
- Slot 3: 1V to 12.6V
- Slot 4: 2V to 16.6V
How It Works:
The display reads the battery’s voltage and maps it to a percentage displayed via 4 LEDs (each representing 25%). This percentage is derived from the battery’s voltage and is useful for estimating remaining battery life. Accuracy may vary depending on battery condition, temperature, and usage habits. Always use the display as an indicative tool and not a precise battery capacity meter.
Applications:
- Battery-powered electronics
- Electric bikes and scooters
- Portable power stations
- DIY electronics and Arduino/Raspberry Pi projects
