Type-C 5V to 4.2V TP4057 Lithium Battery Charge & Discharge Protection Module

Power your next portable DIY electronics project with this ultra-compact Type-C 5V to 4.2V Lithium Battery Charge/Discharge Module. Designed specifically for 3.7V and 4.2V 18650 lithium cells, this board provides a reliable boost power supply while seamlessly managing the entire charging cycle. It features built-in battery protection circuitry to actively prevent overcharging, over-discharging, and dangerous short circuits, ensuring the maximum lifespan and safety of your lithium batteries.

Whether you are building a custom power bank, upgrading an older device to Type-C, or integrating standalone power into your Arduino Uno, ESP32, or IoT projects, this module offers a complete power management solution. Its small footprint and clearly labeled B+ and B- solder pads make it incredibly easy to integrate into tight enclosures, custom PCBs, and automated robotic builds.

Features:

• Integrated Protection: Built-in safeguards against over-charge, over-discharge, and short-circuit scenarios to protect your cells.
• Modern Connectivity: Features a robust, universally compatible Type-C USB interface for convenient 5V input power.
• Broad Compatibility: Optimally designed for standard 3.7V nominal (4.2V peak) lithium-ion cells, including popular 18650 batteries.
• Charge/Discharge Functionality: Acts as a complete power management system, handling both power input and safe power delivery to your load.
• Compact Form Factor: Easily fits into miniature 3D printed enclosures and tight, space-constrained project spaces.

Package Includes:

1 x Type-C 5V to 4.2V Lithium Battery Charge & Discharge Module
