Customer Questions & Answers
Is this TP4056 charger compatible with any lithium battery, or are there restrictions regarding cell type or capacity?
The TP4056 module is mainly designed for charging single-cell Li-Ion and Li-Po batteries (3.7V nominal, 4.2V full charge). It is not suitable for other battery types or multi-cell series configurations. The ideal battery capacity should be at least equal to the charging current (1A), but this value should be adjusted according to the manufacturer’s specifications to maximise service life. For lower-capacity cells, the charging current may be excessive.
What happens if I connect the battery with reversed polarity?
The TP4056 does not have reverse polarity protection. If the battery is connected the wrong way round, there is a high risk of damaging both the battery and the module, and it could cause dangerous short circuits. Extreme care should be taken when connecting it, and polarity should always be checked before powering the circuit.
How is it connected to the power supply, and what options are there if I do not want to use the micro USB?
It can be powered via the standard micro USB connector (5V), or through the 'IN+' and 'IN-' input pins by soldering wires directly to the board. The input voltage must be kept between 4.5V and 5.5V for correct operation. Exceeding this range may damage the module.
What risks are there from overheating during charging, and up to what ambient temperature is it safe to use the module?
The module is designed to operate between -10°C and +85°C. At loads close to 1A, the chip and PCB may become noticeably warm; if ventilation is insufficient, reduce the current or provide additional heat dissipation. It is recommended not to exceed 60°C on the board itself, and temperature should always be monitored in hot environments to avoid premature degradation or failure.
What is the maximum charge current of the TP4056 charger?
The maximum charge current is 1A (1000mA).
Does the module have overcharge protection?
Yes, it includes battery overcurrent protection up to 3A and over-discharge protection at 2.5V.
Can the charger be powered with a micro USB cable?
Yes, the module can be powered via a micro USB cable or by soldering directly to the board.
What is the charger’s full charge voltage?
The full charge voltage is 4.2V, suitable for lithium batteries.
Can I use this charger for Arduino projects?
Yes, it is ideal for Arduino projects and other electronic devices requiring adjustable linear charging.
