I have a drawing on my web site for a simple dual battery set up. It's what I
have used exclusively in my scale ships for about 5 years now. No complaints
yet. I do use 5 cells which helps adjust for the slight voltage drop across the
diode. Note the comments on the site about diode choices. There are even simpler
setups (dual batteries/dual switches/no diodes) but they loose the advantage of
isolating a shorted cell or wiring in one of the packs.
