1. Isingeniso

This manual provides detailed instructions for the safe and effective use of the Tefola IP2312 Type C Input 5V to 4.2V 3A Polymer Ternary Lithium Battery Fast Charging Board. Please read this manual thoroughly before operating the device to ensure proper functionality and to prevent damage or injury.

2. Ulwazi Lokuphepha

• Ukuhambisana: This charging board is designed for Polymer Ternary Lithium Batteries with a 4.2V charging cut-off voltage. Ikona akufaneleki to 3.2V lithium iron phosphate batteries.
• Ukuvikelwa: This product does not include a power indicator function or a battery protection function. External battery protection circuits may be required depending on your application.
• Voltage: Qinisekisa ivolumu yokufakatage is within the specified range of 4.5V to 5.5V. Exceeding this range may damage the board.
• I-polarity: Always observe correct polarity when connecting the battery and power input. Incorrect connections can cause damage to the board and battery.
• Okwamanje: The default charging current is 3A. Modifying the current requires adjusting the resistance on the board. Exercise caution if attempting this modification.
• Imvelo: Operate the charging board in a dry, well-ventilated area, away from flammable materials.

3. Umkhiqizo Uphelileview

The Tefola IP2312 charging module is a compact and efficient solution for fast charging 4.2V polymer ternary lithium batteries. It features a Type-C input port for convenient power supply and utilizes a full CC/CV (Constant Current/Constant Voltage) charging mode.

5. Setha

Follow these steps to set up the charging board:

1. Xhuma Ibhethri: Connect the positive terminal of your 4.2V polymer ternary lithium battery to the B+ pad on the charging board. Connect the negative terminal of the battery to the B- pad. Ensure correct polarity.
2. Xhuma Okokufaka Amandla: Connect a 5V power source (e.g., a USB wall adapter or power bank) to the Type-C input port on the board. Alternatively, you can connect a 4.5V-5.5V power source directly to the KU+ (positive) and NGA- (negative) pads.
3. Qinisekisa Ukuxhumana: Double-check all connections for correct polarity and secure contact before applying power.

6. Iziqondiso Zokusebenza

The IP2312 charging board operates in a full CC/CV (Constant Current/Constant Voltage) mode to efficiently charge lithium batteries.

• Trickle Charging Mode: Lapho ibhethri elixhunyiwe voltage is below 3V, the board enters trickle charging mode, supplying a charging current of 100mA to safely pre-charge the battery.
• Constant Current (CC) Charging Mode: Kanye ibhethri voltage exceeds 3V, the board switches to constant current charging mode, delivering the set constant current (default 3A) to the battery.
• IConstant Voltage (CV) Charging Mode: Njengoba ibhethri voltage approaches 4.2V and the charging current drops below 300mA, the board transitions to constant voltage charging mode. The voltage is maintained at 4.2V until the battery is fully charged.
• Ukuqedwa kokushaja: The blue indicator light will illuminate when the battery is fully charged.
• Recharge Trigger: If, after being fully charged, the battery voltage drops below 4.1V, the charging process will automatically restart to maintain optimal charge.
• Charging Interruption: During the constant voltage mode, charging pauses every 4 minutes to detect the battery voltage. Uma ibhethri voltage is detected to be higher than 4.15V, charging stops. Otherwise, charging continues for another 4 minutes before re-detection.

Izibani zezinkomba:

• Ukukhanya Okubomvu: Indicates the board is actively working/charging.
• Ukukhanya Okuluhlaza: Ikhombisa ukuthi ibhethri ishajeke ngokuphelele.

7. Isondlo

The Tefola IP2312 charging board requires minimal maintenance:

• Keep the board clean and free from dust and debris.
• Avoid exposing the board to moisture or extreme temperatures.
• Regularly inspect connections for any signs of wear or corrosion.
• Do not attempt to disassemble or modify the board beyond adjusting the charging current resistance, as this may void any implied warranty and could lead to damage.

8. Ukuxazulula izinkinga

If you encounter issues with your charging board, consider the following:

• No Charging / Red Light Off:
  • Check if the input power source is connected correctly and providing 5V.
  • Verify that the battery is connected with correct polarity to B+ and B-.
  • Qinisekisa ukuthi ibhethri ivolumutage is not already at 4.2V (fully charged).
• Blue Light Not Illuminating After Extended Charging:
  • Confirm the battery is a 4.2V polymer ternary lithium type.
  • Check the battery's health; a severely degraded battery may not reach full charge.
  • Ensure the charging current is appropriate for the battery capacity.
• Ukushisa ngokweqile:
  • Ensure adequate ventilation around the charging board.
  • Verify that the charging current is not excessively high for the battery or the board's thermal limits.
