I need Automatic, absolutely no question about that personally.
I also am willing to "go overboard" on maximizing bank lifetime, so I need to spend more money on infrastructure, and especially time figuring things out.
Maybe not strictly "economically rational", but currently something I enjoy.
Putting battery monitors "in charge" with relay switches, maybe running a vanilla power supply through a good solar controller, looking at SC which are designed to integrate with monitors. . .
All good fun.
