AMEN to this.  I've had my KX3 since they started shipping the kits and 
installed the KXBC3 as soon as I could get one.  I've been doing Elecraft 
demo's at hamfests for a few years now and I usually have the KX3 on external 
power and if I don't have an antenna connected, I have a dummy load hooked up.  
I keep the power set to 10 watts and it always amazes people who haven't seen 
the KX3 before when I accidentally (deliberately) yank the external power plug 
and the rig stays operating but the power automatically reverts to 5.0 watts.  
This rig is about as bulletproof as Wayne could make it.

The only major thing they slipped up on in the beginning has been taken care of 
by an aftermarket product by a company called "Gems Products" and it's the 
SideKX protective end panels and the Lexan cover that help keep the knobs & 
display from getting banged up in transport.  

The Eneloop batteries have been in my KX3 since it was built and I've NEVER had 
them self-discharge enough to cause the KX3 to shut down and I use it often.  I 
don't usually charge them until the pack's indicated voltage gets down to 
around 9.3 volts under load and then an 8 hour charge puts things back to where 
it was.

You DO have to have at least 13 volts of external power to be able to charge 
them with the KXBC3.  Any less and they may not charge properly.  Even a big 12 
volt external battery pack simply won't provide proper operation of the 
charger.
