Input voltage range: 5~6V
Output voltage: 4.2
Charging current: 1A

Function is introduced
When the charging current drops to 100mA after reaching the final floating charging voltage, the charging cycle will be automatically terminated.
The charging cycle restarts when the battery voltage drops below 4.05V (roughly 80 to 90 per cent of the battery's capacity)
The beginning.
When the battery voltage is below 2.9V, the battery will be precharged at 100mA current.
