Don,
Low battery voltage shut-down can be done quite simply using three or
four parts: a normally open contact relay

Scott,
You are of course correct about hooking the PA directly to the battery
Any body know what is the name of relay that have a gear on
the side, every time the relay energize once it turn the gear
and lock the relay position from normally close
to open and open to close, I have one of the relay that work
that way long time ago, maybe its still available today.

There are undoubtedly many good reasons to consider a more sophisticated
disconnect method than the simple relay circuit described when

Low battery voltage shut-down can be done quite simply using three or
four parts: a normally open contact relay, a resistor, and a cap. The
battery goes to one side of the N. O. contact and the load (repeater?),
power supply, and relay coil to the other N. O. contact. The other side of
