TP4056 1A Li-ion Battery Charging Module with Protection – Micro USB, 5V

Compact Single-Cell Lithium Battery Charger for DIY Electronics

The TP4056 1A Li-ion Battery Charging Module is a compact and practical solution for charging compatible 3.7V single-cell lithium-ion batteries using a standard 5V USB power source. Designed around the TP4056 charging controller, this Micro USB battery charging board provides controlled charging with a nominal charging termination voltage of 4.2V.

For supported board variants equipped with a separate battery-protection circuit, the module can also provide protection against selected battery fault conditions, such as over-discharge and overcurrent. This makes it useful for electronics prototyping, rechargeable battery projects, portable devices, and DIY power solutions.

Whether you are a student, electronics hobbyist, or embedded-systems developer, the TP4056 1A lithium battery charger module offers a convenient way to integrate single-cell battery charging into your project.

Key Features of the TP4056 Charging Module

• 1A Charging Capability: Supports a charging current of up to 1000mA, subject to the module's current-setting resistor, input supply, temperature, and battery requirements.

• 5V USB Input: Uses a Micro USB connector for convenient connection to a suitable 5V USB power source.

• 4.2V Charging Termination: Designed for conventional single-cell lithium-ion batteries with a nominal voltage of 3.6V or 3.7V and a full-charge voltage of 4.2V.

• Constant-Current/Constant-Voltage Charging: The TP4056 controller uses CC/CV charging to manage the charging process.

• Battery Protection on Supported Versions: Protection-equipped boards may include additional circuitry for over-discharge and overcurrent protection. Confirm the exact circuit on your supplied module.

• LED Charging Indicators: Many versions use onboard LEDs to indicate charging and charge completion; verify the indicator colors on your actual board.

• Compact PCB Design: Suitable for integration into space-conscious electronics prototypes and small rechargeable devices.

• Simple Battery Connections: Common board layouts provide B+ and B− battery terminals. Protection-equipped variants may also provide OUT+ and OUT− load terminals.

Technical Specifications

Specifications may vary between manufacturers and board revisions. Confirm the exact module before publishing protection features, dimensions, current limits, or LED behavior.

Applications

1. 18650 Lithium-Ion Battery Projects

Use a compatible TP4056 18650 battery charging module to charge a single suitable 18650 lithium-ion cell in a properly designed battery project.

2. DIY Power Banks and Portable Electronics

Integrate the module into suitable rechargeable electronics prototypes. A complete power bank may require additional power-management, output-voltage regulation, and load-sharing circuitry.

3. Arduino and Embedded Electronics

Explore battery-powered sensor nodes, small controllers, and other embedded projects that need a rechargeable single-cell battery.

4. IoT and Wireless Projects

Use the module as part of a suitable battery-charging arrangement for low-power monitoring devices, wireless prototypes, and connected electronics.

5. Educational and Hobby Projects

The TP4056 is useful for learning about lithium battery charging, power management, PCB connections, and rechargeable electronics.

How to Use the TP4056 Module

1. Check the battery: Confirm that your battery is a compatible single-cell lithium-ion or lithium-polymer type with a 4.2V full-charge specification.

2. Check the board: Identify whether your module has a built-in protection circuit and locate its labeled terminals.

3. Connect the battery: Connect the battery to B+ and B−, observing the correct polarity.

4. Connect USB power: Supply the board with a suitable regulated 5V source through the Micro USB connector.

5. Monitor charging: Observe the onboard indicators if provided and follow the specific module's documentation.

Safety note: Incorrect polarity can damage the module or battery. Do not charge damaged, swollen, leaking, or unsuitable batteries. Use a charging current appropriate for the battery manufacturer's specifications, and do not leave experimental battery-charging setups unattended.

Important Compatibility Notes

• This module is intended for one lithium-ion cell, not a 2-cell or 3-cell series battery pack.

• The standard TP4056 charging controller is not, by itself, a complete battery-protection system. Protection depends on additional circuitry fitted to the board.

• A protection circuit does not replace correct battery selection, wiring, current setting, or safe charging practices.

• The module is not a regulated 5V output converter. A separate boost converter may be needed for projects requiring a regulated 5V output from a single-cell battery.

• Simultaneous charging and powering of a connected load may require a separate power-path or load-sharing circuit.
