Description of TP4056 Lithium Battery Charger with Boost Converter

This module is a compact solution for charging and powering single-cell 3.7V lithium batteries (such as 18650 or polymer batteries). It supports both charging and boost output functions, making it ideal for portable electronic projects. With built-in protection features and clear LED indicators, it ensures safe and reliable performance.


Key Features

  • Wide input voltage range: 4.2V–6.5V (recommended 5V).
  • Adjustable boost output: 4.2V–28V, up to 5W power.
  • Constant current/constant voltage charging with over-temperature protection.
  • 0V battery activation and 2.9V trickle charging support.
  • Programmable charging current up to 1A (linear charging).
  • Soft start to limit inrush current.
  • Reverse connection and discharge protection (depending on model).
  • Dual LED indicators for charging, standby, and fault status.
  • Type-C input interface and solder joint input options.

LED Indicator Description

  • Charging: Red LED ON, Blue LED OFF.
  • Fully Charged / Standby: Blue LED ON, Red LED slightly ON.
  • Boost Mode with Load: The Red LED may remain on, depending on the load.
  • No Load/Idle: Blue LED on, Red LED dim.

Battery Connection Guidelines

  • With Protection Board Battery: Connect B+ and B–, short-circuit the T point before use.
  • Without a Protection Board Battery: Use a module with built-in discharge protection. Do not short-circuit the T point; otherwise, protection will fail.
  • Connect batteries in parallel only (not in series).
  • Ensure good wire contact and avoid thin/long wires to reduce voltage drop.

Usage Notes

  • Linear charging design: slight heating is normal during operation.
  • Charging current should be ~0.37× battery capacity (e.g., 1000mAh battery → 370–400mA charge current).
  • During boost mode, higher currents may cause noticeable heating; this is normal and protected by thermal shutdown.
  • Output voltage can be adjusted using a screwdriver on the onboard potentiometer.

Applications

  • Portable electronics
  • Microcontrollers (Arduino, ESP32, etc.)
  • LED lights and small fans
  • Safe charging of 3.7V Li-ion batteries
  • Portable power supply/boost output projects
