TP4056 USB C Battery Lithium 18650

The TP4056 USB-C Battery Lithium 18650 Charger Module is an excellent solution for powering your lithium-ion battery projects with ease and efficiency. This module is designed to work with rechargeable 18650 lithium-ion batteries and is equipped with a TP4056 chip, specifically engineered for charging these types of batteries. The addition of a USB-C port ensures fast and convenient charging without needing to remove the battery, making it perfect for portable projects and DIY electronics.

One of the standout features of this module is its built-in battery management system (BMS), which provides essential protection for your batteries. It includes under-voltage and short-circuit protection, ensuring the safety and longevity of your battery. This is crucial when working with lithium-ion batteries, as it prevents damage caused by overcharging or discharging too deeply. With a full charge voltage of 4.2V, the module also includes LED indicators that show the charging status—red for charging and blue for when the battery is fully charged.

This module is highly versatile and ideal for a wide range of applications, from powering microcontrollers to lighting up LEDs. Whether you're building a portable device or adding battery-powered functionality to an existing project, the TP4056 USB-C Charger Module offers a reliable and safe solution. The convenience of charging through a USB-C connection means you can easily integrate this module into modern electronics projects, ensuring your lithium-ion battery stays charged and ready for use at all times.
