I have read this question and its answers : How a battery is being charged and used as the same time?
Question 1 : I would like to know if the same concept can be applied to Lithium battery.
Question 2 : Let's say that the battery is being used, I plug the charger, what happens at this special moment, electrically speaking ?
My use case is this : I built a portable speakers box, a Lithim battery is inside (24V and 18Ah). I have a charger that delivers 24V and 5A. The little amplifier inside can use up to 5A. I want to know if there is no risk from plugging ang unplugging the charger when the music plays.
Schematic diagram of my use case :
Constraint 1 : The vuemeter must not work when the system is OFF.
Constraint 2 : The charger must charge the battery when the system is ON and OFF.
Constraint 3 : The charger must provide the charge to system when it is plugged, instead of discharging the battery.
