Steve, If you use a station power supply as both a power source and charger, you'll want to investigate methods for isolating the battery from the power supply/charging source. I've been using a West Mountain Super PowerGate device with an Optima Blue, gelled 80A marine battery.
http://www.westmountainradio.com/SuperPWRgate.htm The PowerGate is an instant-switching device and can be configured to work with gelled, AGM or lead-acid batteries. It uses three ports: (1) battery; (2) power supply; and (3) common output, each using an Anderson Powerpole connector. The output of my PowerGate is connected to a 12-port RigRunner power manifold for distribution to all the +12V shack equipment.
