4 Power Indicator Battery Detection Module
Monitor Battery Levels at a Glance with 4-LED Visual Indication
Never get caught off guard by a dead battery again. The 4 Power Indicator Battery Detection Module provides a clear, real-time visual display of your battery's remaining charge using four color-coded LEDs. Designed for DIY enthusiasts, robotics builders, and portable electronics projects, this compact module makes battery monitoring effortless and intuitive.
Key Features
- 4-Level LED Indication: Four LEDs (typically green, yellow, and red) light up progressively to show battery charge status from full to low
- Wide Voltage Compatibility: Designed to work with common battery configurations including 1S-4S lithium-ion/LiPo packs (specific voltage range varies by version)
- Real-Time Monitoring: Continuously detects and displays remaining battery power without manual intervention
- Compact & Lightweight: Ultra-small PCB footprint makes it easy to integrate into enclosures, dashboards, and portable devices
- Simple Wiring: Only two connections required - positive and negative - for instant operation with no programming needed
- Low Power Consumption: Minimal current draw ensures the module itself doesn't significantly drain your battery
- Clear Visual Feedback: Bright LEDs are easily visible in various lighting conditions for quick status checks
Specifications

| Support | Email & WhatsApp 24/7 |
How It Works
The module uses a series of voltage comparator circuits to measure the input battery voltage. As the voltage drops from a full charge to a depleted state, the LEDs turn off sequentially:
- 4 LEDs lit -> Battery fully charged
- 3 LEDs lit -> Approximately 75% charge remaining
- 2 LEDs lit -> Approximately 50% charge remaining
- 1 LED lit -> Low battery - consider recharging soon
- 0 LEDs / blinking -> Critically low - recharge immediately
This simple analog approach requires no microcontroller, no software, and no calibration - just connect and monitor.

Frequently Asked Questions
Is this module 100% authentic?
Yes, sourced directly from authorized distributors. Every unit is verified for authenticity and quality before shipping.
What battery types does this work with?
It works with lithium-ion, LiPo, and lead-acid batteries within the supported voltage range. Check the specific voltage thresholds of your version to match your battery configuration (1S, 2S, 3S, or 4S lithium packs are commonly supported).
Do I need a microcontroller or programming?
No. This is a purely hardware-based module. Simply connect VCC and GND to your battery terminals, and the LEDs will automatically indicate the charge level.
Can I use this while the battery is charging?
Yes, the module provides real-time voltage-based indication, so the LEDs will update as the battery charges or discharges.
What warranty is provided?
7-day warranty on manufacturing defects covering manufacturing defects. Replacement guaranteed
