Product Description

The GY-6GS Battery Power Display Meter is a versatile and precise monitoring module designed to provide real-time data on battery health and capacity. Featuring a vibrant green LCD, this meter displays both the numerical voltage and a visual percentage bar, making it easy to track power levels at a glance. It is engineered with a wide input range (12V-84V), allowing it to work seamlessly with various battery chemistries, including Lithium-ion packs and Lead-Acid batteries. Its compact, snap-in design is ideal for integration into electric vehicle dashboards, solar power banks, and portable energy storage systems.

Key Features

Universal Chemistry Support: Easily programmable to monitor Lithium (3S-20S), Lead-Acid (12V-72V), or LiFePO4 batteries via the onboard setup button.
Dual-Mode Display: Simultaneously shows the precise DC voltage and a 10-segment battery capacity bar for comprehensive monitoring.
Ultra-Low Power Consumption: Optimized internal circuitry draws less than 5mA, ensuring the meter itself does not significantly drain your battery bank.
Reverse Polarity Protection: Features integrated safety measures to prevent module burnout if the input wires are accidentally swapped during installation.
Wide Operating Range: Capable of monitoring high-voltage systems up to 84V, making it suitable for 48V, 60V, and 72V e-bike or e-scooter battery packs.

Technical Details

Enclosure: Durable ABS plastic with a snap-fit bezel.
Customization: Sleep mode and power-off memory functions included.
Installation: Simple 2-wire connection (Red: Positive, Black: Negative).

Prototyping and Engineering Tips from Robogears

The "First Run" Calibration: This meter is universal and must be programmed for your specific battery type before use. To enter setup mode, hold the "Settings" button while powering on the module. Select the correct code (e.g., 'L' for Lithium, 'P' for Lead-Acid) and the correct number of strings to ensure accurate percentage readings.
Voltage vs. Percentage Accuracy: Note that for Lithium batteries, the percentage is calculated based on the discharge curve. If you are using an old battery with high internal resistance, the percentage may "drop" significantly under heavy load and "bounce back" when the load is removed. Always trust the numerical voltage reading for critical decisions.
Mounting Panel Cutout: For a professional "Phygital" retail look in your enclosures, use a precision laser-cut or CNC-milled rectangular hole. The snap-fit clips are designed for panel thicknesses between 1mm and 2.5mm; if your panel is thicker, you may need a small amount of adhesive to secure the bezel.
Outdoor Use Protection: While the LCD is high-contrast, the module is not fully waterproof. If installing this on an e-bike or outdoor solar box, apply a thin layer of clear silicone around the bezel edge and use a transparent acrylic shield to prevent water ingress into the internal electronics.

Package Includes

1 x 12-84V GY-6GS Battery Power Display Meter (Green)
1 x 2-Pin Connection Cable

Disclaimer: Do not exceed the 84V maximum input limit, as voltage spikes from chargers or motor controllers can exceed this threshold and damage the display. Ensure the battery chemistry settings are correctly matched to avoid inaccurate capacity displays. Always double-check polarity before final connection.
