[Elecraft] Battery power problems.

[Mike Scott]

Why don't you measure the voltage drop with a volt meter and let us know
what it is? A 52-AH battery should be sufficient to run a 100 watt rig but
as batteries age their internal resistance increases with the effect seen as
a higher drop in terminal voltage under load. There could also be a weak
cell in the battery.
I would like to see the battery terminal voltage when the battery is under
full load.

Thanks for the replies.  I am using #12 wire, with Anderson powerpole
connectors.  The battery cable is about eight inches long, and it goes to a
Rigrunner.  The cable for the K2 is also # 12, and it is about one foot or
so long, also hooking up to the Rigrunner.  When I switched to the power
supply (Alinco DM-330MV) it was also connected to the Rigrunner, with a
little bit longer #12 cable.  What cable size should I use?  Maybe 52 Ah. is
too little for the K2/100?  Tom
