Doug:
In order to run the K2 at full power for an extended period of time I
use a 73 Amp-hour gelled electrolyte battery and a PG40S SuperPWRgate
both from West Mountain Radio. The regular station power supply
furnishes charging power.
I cannot tell you how long it will last because I've never run it
down, but I did some duty cycle calculations that showed that it
should last for most of a day of round the clock operation at 100
watts CW, and at least a week at 5 watts.
I have found as several other list members have reported, that the
voltage drop through the diodes in the PG40S does not lead to any
problems for operating the K2.
Drawbacks: 1) This is not a cheap configuration, plan to spend close
to $300 by the time you include fuses, powerpoles, battery connectors
et cetera. 2) It is not conveniently portable; the battery weighs 58 pounds.

What are folks using in terms of an external battery for the K2?
I'm sure there are lots of options, so please include
advantages/disadvantages of each.
I've look at the archive and unless I'm doing something wrong, I don't
get a lot of hits with respect to the k2.
Thanks,
