Charging Module Li-Po/Li-Ion 5VDC 1A USB B micro TP4056

The OKY3402-1 charging module offers a compact and efficient solution for charging single-cell lithium-ion and lithium-polymer batteries. It provides reliable battery charging for DIY electronics projects, portable devices, and more.

Key Features - Linear Charging: Provides a constant current/constant voltage (CC/CV) charging method.

- Adjustable Charging Current: The charging current can be adjusted up to 1A by changing the Rprog resistor.

- LED Indication: Features an LED indicator for charging status (red: charging, blue/green: fully charged).

- Input Interface: Micro USB connector for easy connection to a 5V power source.

- Protection Features:

- Overcharge protection to prevent the battery voltage from exceeding a safe limit.

- Over-discharge protection to prevent the battery from being discharged below 2.5V.

- Overcurrent protection to cut off the circuit if the discharge current exceeds 3A.

- Short circuit protection.

Applications and Benefits - DIY Projects: Ideal for charging Li-Po/Li-Ion batteries in custom electronic projects.

- Portable Devices: Suitable for use in power banks, handheld devices, and other portable electronics.

- Battery Maintenance: Helps maintain optimal battery health by preventing overcharging and over-discharging.

- Easy to Use: Simple to connect and use, requiring no additional components.

Additional Information This module includes a TP4056 charging IC and may include a DW01 battery protection IC. It provides under-voltage cut off / deep drain protection. The charging current can be modified by changing the resistor connected to the R3 position on the board. For optimal performance, disconnect the load during charging. This module is designed to charge 3.7V batteries, providing a full charge voltage of 4.2V.
