USB Mini LiPo Charger (1A Max)

This is the charging module for single-cell lithium or multiple parallel Li-ion / Li-Po batteries, charging port can get power from the USB.

The charging current is the best battery capacity is 0.37C, 0.37 times the capacity for Li-Ion and 1C for Li-PO batteries.

If 5V input voltage is high, such as 5.2 or 5.5, will cause the charging current is less than 1000mA, this is normal. High voltage chip heating will automatically reduce the charging current, not to the chip burned. Chip in 60 degrees fever is normal. After all, the charging current.

Please note: Input reverse connection has no effect on the chip, but the output (battery) reverse connection will damage the chip.
