Keith,
This would work fine and would discharge the batteries unequally - not a problem as long as you charge them unequally, too. Separate 12v chargers would do the trick.
A 48 to 12 or 48 to 24 converter would work too and not discharge the batteries unequally but that's more complexity and cost too.

Subject: [Electric Boats] Re: Sitting at my desk -- musing.
Someone mentioned earlier "drawing off the middle" - which I think means drawing from the center of a string - so you get 1/2 the total voltage at that point. 24V "appliances" are relatively common and you'd then have good amps available as well as the proper voltage using a 48V string.
Would this work? Does it drain the batteries unequally? This seems a good way to get 24V for "house" including high-amp appliances like winches if so.
