3S 11.1V 10A 18650 Lithium Battery Overcharge And Over-current Protection board-Good Quality

3S 11.1V 10A 18650 Lithium Battery Overcharge and Overcurrent Protection Board

This high-quality protection board ensures the safety and security of 3S lithium battery packs. It is designed for use with:

• 10.8V: Rated voltage of polymer batteries
• 11.1V: Rated voltage of 18650 or 3.7V lithium batteries
• 12.6V: Full charge voltage of lithium batteries

Features:

• Overcharge Protection: Prevents the battery from being overcharged, ensuring longer battery life.
• Overcurrent Protection: Safeguards against excessive current draw.
• High Quality: Ensures reliability and longevity of the battery pack.

Notes:

• Measurement Tolerance: Allow 1-3mm errors due to manual measurement.
• Color Display: Colors may appear slightly different on different monitors due to calibration differences.

Usage Instructions and Precautions

• Discharge Rate and Current: For products requiring a discharge current higher than 3A, ensure the battery discharge rate is above 3C.
  • Multiplier Calculation Formula:
    • 1C Battery: 2000mAh capacity = 2A maximum working current (2AH * 1 = 2A)
    • 3C Battery: 2000mAh capacity = 6A maximum working current (2AH * 3 = 6A)
• Battery Voltage Consistency: When using batteries in series, ensure each battery has the same voltage. If not, charge each set of batteries to the same voltage before use.
• Voltage Drop Monitoring: During discharge testing, the battery with the fastest voltage drop indicates a difference in battery capacity and performance.
• Activation: After connecting the board, charge the battery pack (charge voltage 12.6V) to activate the protection circuit and enable output.

Connection and Configuration:

• Battery Configuration: 3S (series combination of three 18650 batteries or lithium polymer batteries)
• Voltage Ratings:
  • 10.8V: Polymer battery rated voltage
  • 11.1V: 18650 or 3.7V lithium battery rated voltage
  • 12.6V: Lithium battery full charge voltage

Additional Warnings:

• Heating: If the battery heats up during use, it indicates the battery is not suitable for the application. Continuing to use it in this state can cause damage.
• Long-term Use: Do not use batteries that are not suitable for long periods, as this can lead to rapid battery damage.

This protection board is designed to manage and safeguard your 3S lithium battery packs effectively, providing reliable overcharge and overcurrent protection for various applications.
