Brett : One very simple solution is to use a 10 X AA Holder and fill it with AA NiMH cells. You can get decent quality NIMH cells at capacities around 3 Ah which will go a long way with the K1. Often you can buy multipacks of AA NiMH along with a quick charger at a very low price these days.
I did a quick google search and this is the first source that I found ... http://www.batteryprice.com/10xaabatteryholder.aspx Michael VE3WMB / VA2NB P.S. I often use 8 X AA NiMH R/C packs to power my KX1 / K1. The K1 will chug along very nicely at 3W with 10V in. >From: Brett Howard <br...@livecomputers.com> >Date: January 10, 2011 12:04:57 AM EST >To: elecraft <elecraft@mailman.qth.net> >Subject: [Elecraft] K1 Battery Solution >I'm looking for a good low weight small volume battery solution for using >with the K1.
