TP4056 1A Li-Ion Lithium Battery charging Module with Current Protection Micro USB

Keep your lithium-ion batteries charged and protected with our TP4056 1A Li-Ion Lithium Battery Charging Module. This compact module is designed for charging single-cell 3.7V lithium-ion batteries, such as 18650 or 16550s, that lack their own protection circuit. Featuring the TP4056 IC and DW01 battery protection IC, this module offers reliable 1A charge current, cutting off automatically when charging is complete.

  Key Features:  

• LED Indicator: Red for charging, Green for fully charged
• Current Protection: Yes
• Reverse Polarity: No
• Protection Circuit: DW01 battery protection IC protects against over-voltage, under-voltage, and reverse polarity connection

  Specifications:  

• Charging Accuracy: 1.5%
• Charging Method: Linear
• Full Charge Voltage: 4.2V
• Over-Current Protection: 3A
• Under-Voltage Protection: 2.5V
• Input Voltage: 4.5-5.5V
• Rated Power: 4.2W
• Operating Temperature: -10 to 85°C
• Length: 25 mm
• Width: 20 mm
• Height: 6 mm
• Weight: 18 gm

  Using the Module:  

1. Connect a micro USB cable for power or a 5V DC source to the IN+ and IN- pads on the left side.
2. Connect the battery to be charged to the B+/B- pads on the right side.
3. A load (device powered by the battery) can be connected to the OUT+/OUT- pads on the right side.
4. Important: Disconnect the load when charging.
5. The red LED indicates charging in progress, while the green LED indicates a fully charged battery.

  Notes:  

• Ampere Meter Connection: Connect the ampere meter to the 5V input end of the module.
• Charging Current: The charging current should be 37% of the battery capacity for optimal charging (e.g., for a 1000mAh battery, use a current of 400mAh).
• Connection Wire: Ensure the connection wire is not too thick.
• Input Voltage Protection: If the input voltage is too high (e.g., 5.2V), the current will be less than 1000mA due to the protection function of the module.
• No Reverse Polarity: Ensure correct polarity when connecting the battery.

  Package Includes:  

• 1 x TP4056 1A Li-Ion Battery Charging Micro USB Module with Current Protection

Safely and efficiently charge your lithium-ion batteries with our TP4056 1A Li-Ion Lithium Battery Charging Module. Ideal for DIY electronics projects and battery maintenance, this module provides reliable charging and protection features in a compact package.
