Apparently my system does not work then: I've got a bridge rectifier that has two power supplies feeding into it - RS-7 and RS-50, that go into a 100 amp/hour AGM deep cycle battery. The RS-7 is adjusted so that after the voltage drop in the diodes the battery floats at 13.8 volts, the RS-50 is set for 13.8 so only is used when the battery voltage drops a bit and it keeps up the supply when I'm using the transmitter a great deal [on average operation where I'm receiving 99% of the time, I just have the RS-7 on]. This keeps the battery up enough for power failures and transmitting. I leave the RS-50 off most of the time as it's just not needed - 5 amps keeps all the radios warm and the battery topped off.

OK, it's not hi-tech, but my Elmer has been doing this for a long time with no problems. It's also a nice quiet system.

To each their own though.
