TP4056 charger module is a very small module for DIY people, it uses the TP4056 controller and standard configuration is with 1A charge current. It does not include any power supply or tray.

TP4056 board needs a 5 volt power supply, this can either be from a mini usb connector or soldered directly to the board.
The “current resistor” can be replaced for other (lower) charge currents, because it is a 0603 size smd resistor (i.e. very small) it can be difficult to replace it.The boards have a blue led for charging and a red led for done.

The charge led will be on when charging and it will be flashing when no battery is connected.The done led will be on when charging is done or no battery is connected.

TP4056 module uses the internal PMOSFET architecture which eliminates the use of blocking diode. It prevents negative Charge Current Circuit. Thermal feedback regulates the charge current to limit the die temperature during high power operation or high ambient temperature. The charge voltage is fixed at 4.2V, and the charging current is programmable externally with a single resistor. The TP4056 automatically terminates the charge cycle when the charge current drops to 1/10th the programmed value after the final float voltage is reached.

TP4056 Other features include the current monitor, under voltage lockout, automatic recharge, and two status pin to indicate charge termination and the presence of an input voltage.

Note:

  1. TP4056 breakout board does not have Overcurrent protection.
  2. Connect Ampere meter in series with 5V input end.
  3. The charging current is best to be 0.37 times of the battery capacity,
  4. Charging wire can’t be too thin or too long while interfacing.
  5. Make sure the board has good contact with the battery.
  6. Chip at work about 60 degrees fever is normal.
  7. Input reverse connection has no effect on the chip. Rather the output (battery’s) reverse connection will burn out the chip.
