Product Description

TP4056 Lithium Battery Charging Module

USBPowered Charger Board with Protection Circuit for 18650 Liion Batteries

The TP4056 module is a complete constantcurrent/constantvoltage linear charger designed for singlecell lithiumion and lithiumpolymer batteries. It is widely used to safely charge popular batteries like 18650 cells for DIY electronics, portable devices, and Arduino projects. Many modules include a protection circuit to guard against overcharge, overdischarge, and short circuits.

Complete Charging Solution - Combines a linear charger IC (TP4056) with battery protection circuitry (DW01A + 8205A MOSFETs) for safe and reliable operation.
Modern USB TypeC Connection Features an onboard Type-C port for easy power input from a standard 5V USB charger or power bank.
Input voltage is 4.5V to 5.5V DC via the Type-C port or solder pads.
The default charging current is set to 1A via an R3 resistor (1.2kΩ).
The output voltage is fixed at 4.2V for a single Li-ion cell. Do not use it to charge multiple batteries in series.

= Key Features =

+Constant Current / Constant Voltage (CC/CV) Charge Algorithm Ensures safe and efficient charging for singlecell lithium batteries.

+Onboard Protection Circuit - The DW01A IC and dual MOSFETs protect the battery from overcharging, deep discharging, and short circuits.

+Programmable Charging Current - Default is 1A, but the charging current can be changed by replacing the PROG resistor.

+DualColor LED Indicators Shows real-time charging status: Red for charging, Green/Blue for fully charged or no battery detected.

+Automatic Recharge - When the battery voltage drops, the module automatically restarts the charging cycle.

= Applications =

  1. Charging singlecell Liion batteries (18650, 14500, etc.) for portable projects.
  2. Powering Arduino, ESP32, and other microcontroller projects from a battery.
  3. Creating DIY power banks or portable devices.
  4. Replacement for older MicroUSB charging modules with modern TypeC ports.

Wiring Guide

TerminalConnectionDescription
IN (or )5V USB positivePositive from USB Type-C port or solder pad
IN (or )5V USB GNDGround from USB Type-C port or solder pad
B+Battery Positive (+) terminalConnect to the positive terminal of the battery
B-Battery Negative (-) terminalConnect to the negative terminal of the battery
OUT+Load PositivePositive terminal for the device/load, powered by the battery
OUT-Load NegativeNegative terminal for the device/load

> Ensure correct polarity when connecting the battery to B+ and B-.

The OUT+ and OUT- terminals can be used to power a load directly from the battery, but the protection circuit limits the discharge current to around 3A.
Connecting the battery with reverse polarity may damage the module, as the TP4056 does not have built-in reverse polarity protection.

Troubleshooting

Module gets hot while charging:

  • Ensure good airflow and ventilation.
  • Check if the charging current is set too high for your battery capacity (<1000mAh).
  • Reduce the charging current by replacing R3 with a higher resistor value.

Module not charging:

  • Verify the 5V power supply is connected properly and providing 4.5-5.5V.
  • Check the battery connection to B+ and B- and ensure it is not already fully charged (4.2V).
  • Check the LED indicators: Red means charging, Green/Blue means full.

Battery voltage drops quickly or device cuts out too early:

  • The DW01A protection circuit cuts off the output when the battery voltage drops below about 2.5V to prevent deep discharge, which is a normal safety feature.
