I've used the NiZn cells in the KX1 battery pack, and they do provide better
power output.

My biggest problem with them is with the charging options. Its hard to
determine the state of charge of a given cell just by measuring its open
cell voltage, and the charger doesn't seem to want to "top off" cells that
aren't nearly depleted. This makes them more difficult to use in my opinion.

I've gone to using a couple of 6.6v LiFePO4 700 mAh packs wired in series.
They fit into the KX1 just fine and provide ample power output for the
period of time I will usually spend using the KX1 portable. The disadvantage
of these are the lower total capacity of course, and the need for a balance
charger and proper connectors to best charge them up.
