The battery charger structure as follows :

The 3-stage mode charging :

First stage ( constant current ) : The charger will supply constant current for the battery

Second stage ( constant voltage ) : The voltage will be rising under the first stage, when it reach constant voltage value, it will turn into the second stage. The current will be slowly smaller until it reduce to floating value,the CV stage will end.

Third stage ( Floating charging ) : When the current is approaching the value of transition, the charger will cut down to the given current gradually, that means the battery power is full and indicator light turn to green. At this moment, the battery can be stopped charging or keep on trickle current charging for half an hour.

The 180W battery charger specification :

Note: Cut-off point for Li battery is 5% of CC, and it can be setted between 3-10%.
