Product features:

★This module uses a very mature charging chip tp4056, with simple peripheral circuit, good protection performance and high charging accuracy.

★This module is fully mechanical automation, full chip parts manufacturing, and each module will be tested before shipment, with high reliability.

★The current of this module can be adjusted by itself. As long as the fixed resistance in the circuit board is changed, the output can be changed to 100ma-1000ma, which is very convenient.

☆modularTips for using ☆

Module application scope

★This module is used for charging single lithium battery or multiple lithium batteries in parallel. The charging port can take power from USB.

Instructions / precautions

★The ammeter for testing current can only be connected in series at the 5V input terminal of the charging board.★The charging current is 0.37c of the battery capacity, which is 0.37 times of the capacity. For example, the charging current of 1000mah battery is 400, which is enough. If the charging speed is too high, the effect will be poor, and the battery voltage will drop more after flushing★The charging connecting wire shall not be too thin or too long. In this way, the connection resistance is large. If it is too thin, the battery voltage will drop more after flushing.★Good contact with the battery. Otherwise, the battery voltage will drop more after flushing.★If the input voltage of 5V is too high, such as 5.2 or even 5.5, the charging current will be less than 1000mA, which is normal. When the voltage is high, the chip heating will automatically reduce the charging current without burning the chip. It is normal for the chip to heat at about 60 degrees in operation. After all, the charging current is large.★The reverse connection of input has no effect on the chip, but the reverse connection of output (battery end) will burn the chip. Please pay attention to the buyer。
