TP4056 Lithium Battery Charger Protection Module

TP4056 Lithium Battery Charger Protection Module Micro USB. The industry-standard solution for charging single-cell $3.7\text{V}$ Lithium-Ion/Polymer batteries. Uses the reliable TP4056 chip for $1\text{A}$ CC/CV charging and includes DW01 protection (on full modules) for over-discharge and over-current safety. Perfect for DIY power banks, portable electronics, and small battery projects.

Product Details

The TP4056 Charging Module is the most widely used linear battery charger module, known for its small size and simplicity. It safely charges single $3.7\text{V}$ Lithium cells using the essential Constant Current/Constant Voltage (CC/CV) method.

• Standard Charging: Charges single Li-ion cells to $4.2\text{V}$ with a default current of $1\text{A}$ (adjustable by replacing a resistor).

• Convenient Input: Features a Micro USB port for power input, making it easy to use with standard phone chargers or computer USB ports.

• Built-in Protection (Optional): Many versions include the DW01A battery protection IC and MOSFETs to prevent the battery from dangerous over-discharge, over-current, and short circuits (Always check if the version includes the protection circuit).

• Visual Status: Clear dual-color LED indicators (Red = Charging, Blue/Green = Full) provide instant feedback on the charge cycle.

• High Reliability: The linear charging method is simple, reliable, and generates minimal electrical noise, though it produces more heat than switching chargers.
