TP4056 1A Lithium battery Special charging board charging module Lithium battery charger

Features:

★ This module uses a very mature charging chip TP4056. The peripheral circuit is simple, the protection performance is good, and the charging accuracy is high.

★ This module is fully mechanized to automate, the full -patch parts are manufactured, and each module is tested before the shipment, high reliability.

★ This module current can be adjusted. As long as the fixed resistance in the circuit board is changed, the output can be changed to 100mA-1000mA, which is very convenient.

Module application scope

★ This module is used for single lithium batteries or multi -section parallel lithium battery charging, and the charging port can be electrified from USB.

Instructions/Precautions

★ The current meter that tests the current can only be connected in the 5V input terminal of the charging board.
★ The best charging current is 0.37C of the battery capacity, which is 0.37 times the capacity. For example, the battery charging current of 1000mAh is 400.The effect of too fast charging speed is poor, and the battery voltage is dropped more!
★ The charging connection wire cannot be too thin and too long.In this way, the connection resistance is large.If it is too thin, the battery voltage is over.
★ It is best to contact the battery.Otherwise, there will be a lot of battery voltage.
★ If the input voltage of 5V is high, such as 5.2 or even 5.5, it will cause the charging current to be less than 1000mA, which is normal.The voltage is high, the chip heating will automatically reduce the charging current, and the chip will not be destroyed.It is normal for the chip to heat up about 60 degrees at work.After all, the charging current is large.
★ The input reverse connection has no effect on the chip, but the output (battery side) reverse connection will burn the chip, please pay attention.
