TP4056 1A Li-ion lithium Battery Charging Module With Current Protection – micro USB

✅ Product Description:

TP4056 1A Li-ion Lithium Battery Charging Module with Current Protection – Type C

This TP4056 1A Lithium Battery Charging Module is designed for safely charging single-cell 3.7V Li-ion batteries. It uses the reliable TP4056 charge controller IC with an integrated DW01 protection IC, offering constant 1A charging current and built-in safety features like over-voltage, over-charge, and over-discharge protection. The Type-C USB input makes it ideal for modern projects and easy powering.

This module is especially useful for DIY battery-powered devices using 18650 cells that lack a built-in protection circuit. When battery voltage drops below 2.4V, it automatically cuts off the load to prevent battery damage.

How to Use:

• Connect a Type-C cable to power the module, or use 5V DC via IN+ and IN- pads.

• Connect your 3.7V lithium cell to B+ and B-.

• You may also connect a load to OUT+ and OUT-, but always disconnect the load during charging.

• LED Indicators: Red = Charging, Green = Fully Charged

Note:

• Use correct polarity: No reverse polarity protection

• Do not charge above 1C rate of your battery capacity

• Best charging current: ~37% of battery capacity (e.g., 400mA for 1000mAh)

• If input voltage >5.2V, the current may auto-limit for chip safety
