There are some cautions in floating a battery with a mains power supply. For example, the ProAudio Engineering PAE-Kx33 4A switching power supply I am using with my KX3 specifically says not to use the power supply for directly charging batteries, and voids the warranty if you do.

I had a prototype battery charge controller I was designing let the magic smoke out when the input power dropped and the battery sent current backwards through the circuit. The tantalum cap was actually in flame. (A diode was part of the fix.)

Like Jim, I use a solar charge controller <http://www.cirkits.com/scc3/> to charge the batteries which run my K3 station.

Is anyone floating a battery across their power distribution?
