Hi, Phil, I remember posting this information some time back but can't find it. So here is a summary:
I found the best solution to portable operation with the KX-1 is to use rechargeable 3.7 VDC Li Ion AA cells. You have to rewire the battery holders so that they are in parallel rather than in series. That gives you three cells in each holder at about 11.1 VDC. The power output when operating portable then approaches the same levels as when operating from a power supply. One source of the cells is at http://www.batteryspace.com/index.asp?PageAction=VIEWPROD&ProdID=1336 . There are many other places to get them as well. You also need a charger that will accommodate the Li Ion. I did find that these cells are minutely smaller than standard AA cells. You can get them to fit snugly into the holder by putting a small blob of solder on the contacts in the battery holders (not on the batteries!). Some KX-1 users have built charging circuitry into the KX-1, but I elected not to do so as it really complicates things. So the batteries have to be removed from the rig for recharging. But there is information on incorporating a built-in charger on the web. Let me know if you have any questions . . . 73, John, WA6L -- View this message in context: http://elecraft.365791.n2.nabble.com/Li-ion-batteries-for-KX1-tp6295637p6303347.html Sent from the Elecraft mailing list archive at Nabble.com. ______________________________________________________________ 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
