10PCS 5V 1A TP4056 Micro USB Charger 18650 Interface Lithium Battery Charging Board DIY Charger Module

1. Features
1). High quality charging chip TP4056, easy circuit, good protection value, high charging accuracy.
2). Complete the processing of mechanical automation, high reliability.
3). Automatically adjust the output current from 100 to 1000mA by simply converting a fixed resistor on the circuit board.

2. Application
It can be used to charge one unit of lithium battery or a serval lithium battery.

5. Note:
1). The ampere meter can only be connected to the 5V Module input port.
2). It is best that the charging current is 37% of the battery capacity. For example, the charging current should be 400 for a 1000mAh battery.
3). The connection wire should not be too thick.
4). Make sure the connection point is good.
5). If the input voltage is too high, for example 5.2V or 5.5V, then the charging current will be less than 1000mA, it is normal. When the voltage is too high, the chip will automatically reduce the charging current to protect the chip from burning damage. Also, it is normal that the chip feels hot when the chip's work temperature is around 60 ℃.
