TP4056 1A Li-ion lithium Battery Charging Module

Power your DIY projects efficiently with our TP4056 1A Li-Ion Lithium Battery Charging Module. This compact and lightweight module is designed to charge 3.7V lithium batteries with ease. Featuring an on-board Mini USB interface, it allows direct connection to a computer USB port for convenient battery charging. Alternatively, an external source voltage can be used via the IN+/IN- pads, making it versatile for various applications.

  Key Features:  

• Charging Indicator: RED LED for charging, BLUE LED for fully charged
• Charge Current: 1A (default); adjustable by modifying the onboard resistor
• High Efficiency: Uses TP4056 chip for simple peripheral circuits, good protection performance, and high charging accuracy
• Automated Processing: Fully machinery automated processing with all patch parts manufacturing
• Adjustable Current: Charging current can be easily adjusted from 100mA to 1000mA by changing the fixed resistors on the circuit board (refer to the linked PDF for details)

  Specifications:  

• Charging Accuracy: 1.5%
• Charging Method: Linear
• Full Charge Voltage: 4.2V
• Input Voltage: 4.5-5.5V
• Length: 25 mm
• Width: 19 mm
• Height: 6 mm
• Rated Power: 4.2W
• Weight: 3 gm

  Important Notes:  

• No Overcurrent Protection: This breakout board does not have overcurrent protection.
• Amperemeter Connection: Connect an ammeter in series with the 5V input end to monitor the charging current.
• Optimal Charging Current: The charging current is best set to 0.37 times the battery capacity.
• Interfacing Cautions: Ensure the charging wire is not too thin or too long, and maintain good contact with the battery.
• Thermal Management: The chip may reach about 60 degrees Celsius during operation, which is normal.
• Reverse Connection: Input reverse connection has no effect on the chip, but reverse connection on the output (battery) side will damage the chip.

  Package Includes:  

• 1 x TP4056 1A Li-Ion Lithium Battery Charging Module

The TP4056 1A Li-Ion Lithium Battery Charging Module is a reliable and efficient solution for charging 3.7V lithium batteries. With its internal PMOSFET architecture, it eliminates the need for a blocking diode and prevents negative charge current circuits. The module features thermal feedback to regulate the charge current, ensuring optimal performance even under high power operation or elevated ambient temperatures. The charge voltage is fixed at 4.2V, and the charging current can be easily programmed with a single resistor.

This module also includes valuable features like current monitoring, under-voltage lockout, automatic recharge, and status pins indicating charge termination and input voltage presence. Ideal for a range of applications, from DIY projects to professional prototypes, the TP4056 ensures your batteries are charged safely and efficiently.
