I think so.  But since it would not fit inside the KX1, what's the 
advantage over using a pack of 10 AA NiMH external to the rig?  The 
latter gives full power and is easy to implement.

But, for those who do like rechargables, but want a full 3 watts, I have something for you. I'm working on a small switcher that will double the NiMH voltage and then linear regulate it to 12 volts. Of course this halves the effective AH rating to begin with and then chops operating time further by upping the TX current. But, I estimate operating time of >10 hours with this approach.
