Attention:
-The ammeter for current testing can only be connected in series to the 5V input of the charging board.
-The best charging current is 0.37C of the battery capacity, which is 0.37 times of the capacity. For example, the charging current of a 1000mAH battery is 400, that is enough. Too much charging current, fast charging speed but poor effect, the battery will be step-down.
-The charging connection wire should not be too thin or too long, which has high resistance, and lead to the battery voltage is step-down.
-If the 5V input voltage is higher, such as 5.2, or even 5.5, the charging current will be less than 1000mA, that is normal. High voltage will lead to the chip heating and reducing the charging current automatically to avoid damaging. It is normal for the chip to heat up to about 60 degrees during operation. After all, charging current is high.
-The input reverse connection has no effect on the chip, but the output (battery end) reverse connection will burn the chip.
