[Jim Wilkie]

Andt, will wait for the experts to answer, but I think the nimh charger 
vs the lopo charger would be a problem.

I've seen external LiFePo4 packs being used, but it seems like an internal solution might be workable.  With a 13.2V supply (four cells in series), one can run the KX3 in full-power mode.  In addition, the discharge curve of LiFePo4 is much better than NiMH.
