Internal AAA batteries for KX1?

[Michael Babineau]

I saw a posting yesterday on QRP-L where someone saw AAA Lithium
batteries
for sale so I went to the Energizer.com site and sure enough it looks
like
Eveready is now manufacturing a 1250 mah AAA Lithium cell.

This got me to thinking about how great it would be if Elecraft offered
an alternative bottom cover for the KX1 that had 2 X 4 AAA holders
giving
12+ V instead of 10V with the 2 X 3 AAs.

I bet that these new AAA lithiums would be good for about 10 hours of
operating, which is a lot.  Heck, maybe you could squeeze in 9 AAAs.
I often use an external 10 AA Nimh pack to get the extra power out
but this can be inconvenient with such a small rig especially when
operating Pedestrian Mobile.

I for one would pay for a second case bottom for my KX1 that allowed me
to use AAA cells rather than AAs. It would be nice to have the
option to use either battery type depending on the circumstances.

P.S. I suppose I could see if Elecraft would sell me another bottom
for the KX1 and I could purchase AAA holders from Mouser or
someplace else and wire up my own.

I have a rechargeable lithium CR-V3 battery for my digital camera-it is 3V
nominal, and the same size as 2 AAs smushed together side-by-side.  The 3+3
cell arrangement in the KX1 precludes using these, but I wonder if someone
is going to come out with a rechargeable lithium AA-or do they already
exist?

FWIW
I use Lithium Ion batteries in RC planes and I also use them with the KX1, K1 and other rigs. However I do not use them in the rig, I have seen too many battery failures over the years (30) to trust charging in the rig. I do have several 3 cell (11.5) volt flat cell packs I use as external source. I like this as I can change packs on the fly and charge them away from rig. As an example a 3 cell flat pack with a rating of 3500 mah is about the size of an 8 cell AA flat pack but thinner and about 1/3 of the weight. They do require a charger that is made specifically for Lithium Ion packs. I carry 2 of these in back pack and get many hours of op time before needing recharged.

How about reducing the depth of the stock KX1 cabinet to a minimum, such
that no batteries fit.  Then engineering a "piggy back" case to fit (snap,
plug, clip,...) on the back of the KX1 that truly seperates batteries from
the radio electronics?  This could be made an option, perhaps with AA or AAA
cells, or even some exotic Li Ion flat pack, or?...

This way you could use the "internal" batteries, or leave the battery
pack/case at home and use external power via connector.

Just my $0.02 worth...
