possibility to use charger and battery at the same time

[dorg]

so, if i understand you right when the charger is on and connected all my components in the robot will get the voltage it suplies 14.2 for example?

is there a way to do this without damaging my components with the extra voltage?
are there any recommended chargers for this?

to make myself clear, i am doing an autonomous robot that needs once in a while to charge itself from the AC power dock
