[Elecraft] Internal AAA batteries for KX1
I just thought that I would mention that 4 X 2 AAA battery holders will fit into the space on the bottom of the KX1 normally occupied by 2 X 3 AA holders. The fit is a little tight but it is ok. The advantage is a bit higher power out than with 6 AAs while running on internal batteries. Since the cost of AAA Lithium cells is crazy I am using 1000 mAh AAA NiMH cells and this gives me enough power for an afternoon outing without having to carry an external battery pack. Rather than cannibalize my existing KX1 case bottom I kept it as is so that I can still opt to go with AA cells. I ordered a spare case bottom and power connector from Elecraft and picked up the AAA holders locally. If anyone is really interested in this drop me a note and I can provide more details.

On my last outing I was able to operate for 2+ hours before I noticed any drop in output power (I was getting 4+ watts out) and that was while operating portable in 5 degree C weather. __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
Re: [Elecraft] Internal AAA batteries for KX1?
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. Tim W4YN From: Eric Ward [EMAIL PROTECTED] 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? Eric N0HHS KX1 #670 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.

RE: [Elecraft] Internal AAA batteries for KX1?
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...
