3.7 V Li-Ion cells in the KX1

[James Kearman]

Bill, AB1AV, pointed me to the site I was thinking of, by WA3WSJ. I
apologize for not mentioning him, his site just didn't show up when I
was searching today.

Very interesting stuff,

One question though...

On batteryspace.com the notes for the Li-Ion 14500
Cylindrical Cell AA size 3.7V 750mAh says,

"You must choose Our Smart Li-Ion Battery Charger and
Battery holder to charge the Li-Ion cell with battery
holder ( please charge one cell per time , please
charge more cell in series) . Never use conventional
DC charger to recharge the Li-Ion battery."

The rig in WA3WSJ pictures seem like it's setup in
parallel with an external charging hookup, isn't that
against what batteryspac suggested?

Just curious, I'm debating still about whether or not
I want to use Li-* based batteries or not for my KX1.

English is not their first language. :) They may not like me charging
two banks in parallel, but so far, so good. They sold me the charger,
but maybe they only want me to charge one set of three cells at a time.

I know that I can recharge daily and I don't expect to operate more than
a few hours each day. The charger folds back at more than 1 amp, so I am
not concerned about Vesuvius On The Elecraft. I will open the bottom of
the case while charging, and I assume the hotel rooms all have smoke
alarms. :)

I've been using non-rechargable lithium AA cells in a KX1 for quite a
while.  Not sure I'd want to use the rechargable ones given the problems
with laptops.
