Detailed Description:

Safely and efficiently charge your single-cell 3.7V Lithium-ion or Lithium Polymer (LiPo) batteries with our indispensable Lithium Battery Charging Module TP4056. This compact board is specifically designed to provide constant current/constant voltage (CC/CV) charging, ensuring optimal battery health and extended lifespan, while its integrated protection features offer crucial safety.

At the heart of this module is the highly reliable TP4056 IC, a dedicated linear charging chip for single-cell lithium batteries. It delivers a default 1A charging current (which can be adjusted by changing an onboard resistor) and maintains a precise 4.2V charging voltage, the standard full-charge voltage for 3.7V Li-ion/LiPo cells.

The module features a convenient B-Type Micro USB input (5V), allowing you to power it directly from standard USB wall adapters, computer USB ports, or even power banks. This makes it incredibly versatile for both development and standalone applications.

Crucially, this TP4056 module comes with integrated battery protection circuitry, typically including a DW01 protection IC and a dual MOSFET (like FS8205A). This protection safeguards your valuable batteries against common issues:

• Overcharge Protection: Automatically stops charging once the battery reaches 4.2V, preventing damage from overcharging.

• Over-discharge Protection: Disconnects the load if the battery voltage drops below a safe threshold (typically around 2.5V), preventing deep discharge that can permanently damage the battery.

• Overcurrent Protection: Limits the current drawn by the load during discharge (typically around 3A), protecting both the battery and the load from excessive current.

• Short-Circuit Protection: Immediately cuts off power in the event of a short circuit on the output, enhancing safety.

Two onboard LED indicators provide clear visual feedback: a red LED typically indicates that the battery is currently charging, while a blue or green LED lights up when the battery is fully charged. This makes monitoring the charging status effortless.

This TP4056 charging module is an essential component for a wide range of DIY electronics, portable devices, and robotics projects, including:

• Charging 18650, 14500, or other 3.7V Li-ion/LiPo batteries.

• Building custom power banks.

• Powering Arduino, ESP32, or Raspberry Pi projects from a rechargeable source.

• Creating portable lighting solutions, wearables, or IoT devices.

• Safely managing batteries in RC models and other battery-dependent applications.

Ensure the longevity and safety of your lithium batteries.

The TP4056 B-Type Charging Module is a micro USB-based lithium battery charger designed for 3.7V single-cell Li-ion or LiPo batteries. Powered by 5V input via B-Type micro USB, it provides a charging current up to 1A and features an onboard battery protection IC to safeguard against overcharging, over-discharging, and reverse polarity.

It is commonly used in portable electronics, IoT projects, ESP32/ESP8266-based devices, and solar-powered systems. The onboard LEDs indicate charging and full-charge status, making it user-friendly and reliable.
