This module is use a USB 5V micro to charge a Lithium ion battery. This charging board comes with LED indication as well. Some notes about this product: • Ampere meter can only be connected to 5V input end of the module. • It is better that the charging current is 37% of the battery capacity. • If you charge to the battery of 1000mAH, current of 400 is enough. If the input voltage is too high, like 5.2V, the current will be less than 1000mA, this is a protection function. • Auto-substract the charging current to avoid burn damage to chip. • Input reverse has no effect on the chip, but the output (battery terminals) reverse will burn chips.
