One of the Elecraft engineers mentioned that they worked hard to find a battery 
holder with low resistance contacts and conductors for the KX3.

Art sees the same thing I do.  Take those 10 springs, uncoil them and fasten 
end to end.  That surprisingly long, hight loss length of wire is what all the 
current has to pass through.  Far from ideal for keeping the voltage and 
efficiency up.

I have seen better designs incorporated into equipment but never in the 
secondary market.
