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,
go to my website
