☆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.
★ 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
After all, the charging current is large. br/ 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. br/ img alt src http //img.dxcdn.com/OverviewImage/YB02460/sku 510022 1.jpg / img alt src http //img.dxcdn.com/OverviewImage/YB02460/sku 510022 2.jpg / br/ /p table class t info tbody tr th class title colspan 2 General /th /tr tr td class
For example, 400m of battery charging current of 1000mAH is enough
High voltage chip heating will automatically reduce the charging current, not chip burned
If it is too thin, then the battery voltage will be lost. br/ It is best to make good contact with the battery
It is normal for the chip to generate heat at about 60 degrees at work
Otherwise, the battery voltage will be lost. br/ If the 5V input voltage is high, such as 5.2 or even 5.5, the charging current will be less than 1000mA
The effect of excessively fast charging speed is poor, and the battery voltage is washed out. br/ Charging connection wire should not be too long
This is normal
This makes the connection resistance large
