[Elecraft] Re: KX1 on AAAs or Lithium Polymer?

[Chris Kantarjiev]

Funny, I was just looking at external battery pack possibilities for
my KX1 last night.

I had clipped out a QST article by AD5X (March 2005) about taking
two 7.2v R/C type NiMH packs and combining them to power his SG-2020.
The voltage is a bit high for the KX1 (16V fully charged), and I didn't
like the idea of 'wasting' charge with dropping diodes. But it's an option.
(It's also heavier than the KX1 - about 2 lbs when done.)

I'm also contemplating an 8-cell NiMH (9.6V) pack. This would be a
good in-the-pocket unit for cold weather ops. The voltage is perhaps
a bit lower than desired. 

LiPoly seems like the 'right' approach for a lightweight radio, even
if it is more expensive. 11.1v in a triple cell pack isn't bad.

I'd be quite interested in an Elecraft-approved solution! I could live
with an external charge controller that just got plugged into the 
external DC jack...
