I alternated batteries so that I always had a charged battery in reserve on the water.
This is not a boat forum.
IF you have access to a reasonably good charging method, like shore power or a generator, there is NO real advantage to using one battery while charging another. The charging source does a fine job of providing power to USE while it also charges the weak batteries.
Two batteries connected together last at least twice as long and even if run down to almost totally flat, the system will have usable voltage again a few seconds after a charging source is attached, assuming that it has sufficient capacity.
IF YOU HAVE A GOOD CHARGING SOURCE, THERE IS NO ADVANTAGE TO USING YOUR TWO BATTERIES ONE AT A TIME. NONE.
I guess you have never been out so far you can't see the shore. We that have understand redundancy.
