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... 73 de chris K6DBG _______________________________________________ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
