TP4056 1A Lithium Battery Charging Board Battery Charger Charging Module, Mini USB Interface

☆Use tips for the module ☆
Module application area
★ This module is used for single-cell lithium or multi-cell lithium batteries in parallel, and the charging port can take power from USB.
 
Instructions/Precautions
★ The current meter for the test current can only be connected in series with the 5V input of the charging board.
★ The charging current is preferably 0.37C of the battery capacity, which is 0.37 times of the capacity. For example, 400m of battery charging current of 1000mAH is enough. The effect of excessively fast charging speed is poor, and the battery voltage is washed out.
★ Charging connection wire should not be too long. This makes the connection resistance large. If it is too thin, then the battery voltage will be lost.
★ It is best to make good contact with the battery. Otherwise, the battery voltage will be lost.
★ If the 5V input voltage is high, such as 5.2 or even 5.5, the charging current will be less than 1000mA. This is normal. High voltage chip heating will automatically reduce the charging current, not chip burned. It is normal for the chip to generate heat at 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 to the buyer.
