Why LiFePO4-Specific Display?

LiFePO4 vs Li-ion Voltage Difference:

• LiFePO4 nominal voltage: 3.2V per cell
• Li-ion nominal voltage: 3.6V-3.7V per cell
• This display is calibrated for LiFePO4's unique voltage curve
• Using Li-ion display on LiFePO4 will show incorrect capacity
• Accurate capacity indication for LiFePO4 batteries

Installation Instructions

Step 1: Select Correct Configuration

• Count the number of LiFePO4 cells in series (S) in your battery pack
• Order the matching configuration (1S to 16S)
• Verify voltage matches your LiFePO4 battery pack

Step 2: Wiring Connection

• Connect positive (+) wire to battery positive terminal
• Connect negative (-) wire to battery negative terminal
• Ensure correct polarity (reverse polarity may damage the board)
• Use appropriate wire gauge for your application

Step 3: Mounting

• Choose a visible location for easy monitoring
• The slim profile (2.8mm thick) fits in tight spaces
• Mount using adhesive or screws
• Ensure blue LEDs are visible and accessible

Step 4: Testing

• Power on the LiFePO4 battery pack
• Verify blue LEDs illuminate correctly
• Check that display shows appropriate capacity level
• Test at different charge levels to verify accuracy

Why Choose This LiFePO4 LED Display?

Important Notes

⚠️ Safety Precautions:

• ❌ Do not use with Li-ion or LiPo batteries (use Li-ion version instead)
• ❌ Do not connect to wrong voltage configuration
• ❌ Ensure correct polarity when wiring
• ✅ Only use with LiFePO4 (Li-Fe) batteries
• ✅ Select the correct S configuration for your battery
• ✅ Double-check wiring before powering on

Usage Tips:

• The display shows approximate capacity based on LiFePO4 voltage curve
• Accuracy may vary under load vs no-load conditions
• Use as a general indicator, not precision measurement
• LiFePO4 has flatter discharge curve than Li-ion
• Recharge when display shows 30% or lower for battery longevity
