Not a bad idea if you don't want to remove your alt completely

If that's true, you would reduce the electrical load on the alternator but the belt still adds some drag.

Two 8 volt golf cart batteries in series would net you 16+ volts. You would have a good buffer until the alt kicks in.

There are also 16v racing batteries for just this application (they know how to get every bit of efficiency) but I don't know if they are deep cycle or not.

P.S. you don't want your alternator to try to charge a deep cycle battery!!!! You might burn it out trying to supply all those amps.
