Mini USB 5V 1A 18650 TP4056 Lithium Battery Charger Module Charging Board

This compact linear charging module, based on the TP4056 IC, provides a complete solution for charging single-cell Li-Ion and Li-Po batteries. It is designed to be powered from a standard 5V source via its Mini USB port, making it a versatile component for various electronics projects.

Key Features
- Charging Method: Employs a Constant Current/Constant Voltage (CC/CV) algorithm to safely and efficiently charge batteries.
- Power Input: Conveniently powered via a standard Mini USB port from any 5V source, such as a USB adapter or computer port.
- Adjustable Charge Current: Delivers a default maximum charge current of 1A. This can be customized for lower-capacity batteries by changing a single onboard resistor.
- Status Indication: Features clear onboard LED indicators to display charging status. A red LED indicates charging is in progress, while a green or blue LED signals that the battery is fully charged.
- Integrated Protection: Includes built-in protection circuits to safeguard the connected battery against overcharge (trips at 4.2V), over-discharge (trips at 2.5V), and over-current conditions.

Applications
Ideal for integrating a rechargeable battery system into custom electronics projects, portable devices, or for building standalone battery chargers. Its small footprint and comprehensive safety features make it a reliable choice for hobbyists and engineers.
