I have 2 batteries fitted, both connected to a switch giving the option of 1, 2 or both.
I normally run on both, for the sole reason that this means that both will get charged by the alternator when running.
These batteries very rarely get charged other than from the alternator.
My question is, is it possible to fit a trickle charger that is connected to the shore supply so when in marinas and connected up it will charge both batteries or can only one be charged at a time?
It would be ideal to be able to connect to shore supply and know that both are getting a good quality slow recondition charge.
I know nothing when it comes to electrickery!
