Thanks to all who responded - I now officially have too many options!
I didn't know about the RV converter solution; I like that idea
and will keep my eye out for a reasonably priced unit for a "real"
setup for my shack.
I'm leaning toward getting a "normal" 30A supply in the short term, since

Chris et al:
A better technique is to use a power supply that is designed to float
across and manage batteries. They call them RV Converters. They are
very cost effective, and at least some of them are very RF quiet. No
diodes are required, and the supplies are designed to withstand the
loads

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.
I think optimizing for the KBT2 is an unnecessary constraint on your new
QRO power system. The charging system for the KBT2 with the resistor is
an expedient and inexpensive solution, but it isn't optimal itself.
I'd recommend putting a separate connector on as Don suggests, fused
directly to

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

Hi George,
I assume that the Astron output voltage is about 13.8 vdc. Assuming a 0.7 vdc
voltage drop across the diode, your deep discharge battery sees about 13.1 vdc.
