The problem of course with the traditional setup is that if you leave
the switch in "Both" you can kill both batteries. And, if the switch
isn't wired with an alternator shutoff, a mistake can kill the diodes.

A better solution is to use some method that automatically combines
when charging, and disconnects otherwise. There are several combiners
that are based on relays that do this. I use a slightly different
technique, an EchoCharge, that gives the stating bats a nice charging
current whenever the main bank is charged from any source.
