Johnny,
Do you have pictures posted?   I remember when you started this project and
I'd like to see how it worked out.

Presonally I lean more toward LiFePO4; although they have a lower energy
density than the Li-Po (though higher power density) they reportedly are
safer in conditions of over/under charge and mechanical stress.

 Hello Wayne,
 
 Yes, K2 is still my favourite field day and QRP rig and no others can bit
 it.
 
 I now have 3 x 3.7v 3300mAH Li-Po cells in the KBT2 and they work very
 well.

 Dear elecraft -team,
 during the last 2 years all new modules and software updates had  
 been designed for the K3. Is the K2 out of the focus or is there a  
 chance for all the K2 users to get new modules and upgrades in the  
 future ?
 
 The K2 is a very mature product, and I don't anticipate adding further  
 internal modules to it. I've thought about a Li-Ion battery as a  
 replacement for the present gel-cell, but it's still too expensive and  
 is thus left as an exercise for the reader.
 
 The P3 should work with the K2, though less tightly integrated than  
 with the K3. If that pans out, we'll post details later.
 
 We have no plans to phase out the K2, which is still going strong  
 after 10 years (for which we thank our customers!).

 Upon replacing the Lead acid battery in the KBT2 with Li-Po cells, the K2
 is now very light weight and can be operated for lng time.  It is the
 greatest portable rig when compared with the others.
 

I liked the lead acid battery because it made the K2 feel solid and not move
about on the desk, when it was my main rig. Now I have the K3, it is really
only a portable and backup rig, so perhaps Li-Pos would be a better option.
But I don't know what to do about charging. I made a PSU for my 10W K2 in an
EC2 case, and adjusted it to deliver 14.2V output, and it has done a good
job of keeping the gel-cell battery charged all these years. Presumably
Li-Pos would need a more complicated arrangement.

My vote would be to bring some of the K3's DSP algorithms - especially the 
noise reduction - to the 
K2's DSP board!
