Bob, Lithium non-rechargeable AA cells will do quite well in the KX1.
Just my personal opinion, but with no personal experience. I would not run rechargeable Lithium batteries inside any transceiver that was not specifically designed for them, and included a specific Lithium charger built in (like laptop batteries). I hear too many horror stories about Lithiums catching fire and that sways my opinion.
Instead, I would suggest LiFePO4 batteries if you wish to install them inside the KX1. 4 3.2 volt cells will give you 12.8 volts when fully charged, so you will need 2 AA battery eliminators (AA sized dowels with a wire from one end to the other) to complete the circuit.
If an external battery pack is a possibility, look at the Buddipole website for their A123 batteries.

What do you use for internal batteries in your KX1? I just got my new (bought used) KX1 cleaned up, tuned up and running nice. It has the output power mod (changed 2 resistors) but with 6 internal 1.5V batteries the 1.4Watt output power is just too low for me. Be for the batteries are dead I'll be running QRPP. I want around 13V which give me 3Watts, but I really want internal batteries. The various formulations of 3.6V rechargable Lithium batteries look appealing but I've heard lots of stories about poor reliability. Any suggestions?
