Chris,
The way I do it with my K2 twins is to use a Smartcharger (directly
connected to the battery terminals - fused of course) to power the base
K2. The base K2 always runs on the internal battery. The high current
supply is connected to the KPA100/KAT100 combination in the EC2 enclosure.
If you find that you need to purchase a new supply just ot keep the
voltage up to where the internal battery will be charged, then the
Smartcharger may be a better alternative.
If you want to see my implementation of the direct battery connection,

I've been running a QRP K2 for about 18 months now. It has the
KBT2, and I've been powering the home station with a 10A linear
PS that's adjusted to 14.2V, to keep the internal gelcell happy.
Now I'm going to add a KPA100/KAT100 in an EC2 (K2 twins!) and
have to upgrade my power setup. My current thinking is to use
the Alinco DM-330 switching PS for space reasons (my shack
shares space with my office :-)
