[Elecraft] Battery back-up system for multiple rigs

[Harry Yingst via Elecraft]

The first thing that comes to my mind is Line Loss
How far are they going to run the lines from the backup batteries to the radios?

Looking for some advice. Trying to help out a friend who is setting up an
emergency communications system for the Hams in their condo group.

They have several marine batteries they want to tie in parallel so they can
run multiple rigs,  K3's plus UHF/VHF for extended periods. They have a
charger for the batteries. They use the 12V off the batteries to a
distribution box for the 12V equipment.

 

Questions:

-          What is the best way to isolate the equipment from the batteries
if something happened to the battery (ies).

-          Is there a way to isolate the batteries from each other if
something happened to one battery so it didn't draw down the other
batteries?

-          Am I missing anything else that should be done for safety of the
equipment, batteries and the operators?

 

Tnx

N2TK, Tony
