I have two batteries on my boat. They are managed through a 
battery switch which enables me to select 1, 2 or both batteries. 
I have a battery charger that I can limit to a 2 amp charge. I 
would like to charge each battery through the cigarette lighter 
receptacle without disconnecting the battery cables. I have a 
plug which I can easily wire to the charger clips. The boat will 
be out of the water (on a lift) while being charged. Could I 
select a battery and plug the charger into the lighter? 
Is this safe for the alternator? Would it work? Any suggestions 
will be appreciated.
BTW, it is a Volvo/penta 5.7 rig.
