TP4056 Battery Charging Protection Module with Micro USB | Li-ion Charger Board

Description TP4056 Battery Charging Protection Module (Micro USB) The TP4056 Battery Charging Protection Module is a compact and highly reliable solution for charging and protecting single-cell lithium-ion (Li-ion) and lithium-polymer (Li-Po) batteries. Designed around the popular TP4056 charging IC, this module provides constant-current / constant-voltage (CC/CV) charging, ensuring safe, efficient, and stable battery charging. Equipped with a Micro USB input, the TP4056 module allows easy powering from common USB sources such as power adapters, power banks, laptops, or USB chargers. It is widely used in DIY electronics, IoT devices, portable gadgets, robotics projects, and battery-powered embedded systems. �� Key Features of TP4056 Battery Charging Protection Module Based on TP4056 lithium battery charging IC Supports single-cell Li-ion / Li-Po batteries (3.7V nominal) Micro USB input for easy charging Built-in battery protection circuit Overcharge protection Over-discharge protection Short-circuit and overcurrent protection LED indicators for charging and full status Compact and lightweight design Ideal for DIY, IoT, and portable electronics ⚙️ How the TP4056 Battery Charging Module Works The TP4056 Battery Charging Protection Module uses a linear charging method with constant current and constant voltage control. When a battery is connected, the module initially charges it with a constant current. As the battery voltage approaches 4.2V, the charger automatically switches to constant voltage mode, gradually reducing the current until the battery is fully charged. In addition to charging, the onboard protection IC and MOSFETs continuously monitor battery conditions. If the battery voltage goes too high, too low, or if a short circuit occurs, the protection circuit automatically disconnects the load to prevent battery damage. �� Technical Specifications Parameter Specification Product Name TP4056 Battery Charging Protection Module Charging IC TP4056 Battery Type Single-cell Li-ion / Li-Po Battery Voltage 3.7V nominal Full Charge Voltage 4.2V ±1% Input Voltage 4.5V – 5.5V Input Connector Micro USB Charging Method CC / CV Max Charging Current Up to 1A (configurable) Protection Functions Overcharge, Over-discharge, Overcurrent, Short Circuit Indicators Charging LED / Full Charge LED Mounting Type PCB Condition Brand New Quality High Quality ��‍�� Compatibility & Integration The TP4056 Battery Charging Protection Module is compatible with: 18650 lithium-ion batteries Flat Li-Po batteries (3.7V) Arduino, ESP8266, ESP32 projects IoT and wearable devices Portable electronics and gadgets DIY power banks Robotics and sensor nodes It can be easily integrated into battery-powered designs using simple solder connections. �� Common Applications This TP4056 module is widely used in: DIY electronics projects IoT and smart devices Battery-powered Arduino projects ESP8266 / ESP32 power management Portable audio devices Power bank DIY kits Wearable electronics Robotics and automation systems Embedded development boards Its simplicity and reliability make it a favorite among students, hobbyists, and product developers. �� Ideal for Education & Prototyping The TP4056 Battery Charging Protection Module is extensively used in: Engineering colleges and universities Electronics training labs IoT and embedded systems workshops STEM education programs Student innovation and final-year projects Students can easily learn battery charging principles, power management, and protection circuitry using this module. ⚠️ Usage Tips & Best Practices Use only single-cell (1S) lithium batteries Do not connect multiple cells in series Ensure correct battery polarity Use proper heat dissipation for high charging current Do not exceed recommended input voltage Avoid charging damaged or swollen batteries �� Package Includes 1 × TP4056 Battery Charging Protection Module (Micro USB) ✅ Why Buy from INFYNIQS Genuine and quality-tested power modules Suitable for DIY, educational & professional use Ideal for bulk and institutional supply Trusted electronic components marketplace Support for IoT and battery-powered projects
