[Elecraft] 4V 450mAH AA Lithium batteries [KX1]

[Leigh L Klotz, Jr.]

Here are some 4V AA Lithium batteries.

Although they have about half of the energy the Energizer drugstore 
Lithium batteries provide, it is at a higher voltage.

Uses inside the KX1, six of these series-parallelled (not series as in 
the current KX1 internal battery circuit!) would provide ~12V at about 
900 mAh.
