Actually, this is quite easy and inexpensive to do. I use one of the biggest 12V batteries that Costco sells (about $75) and float charge it with a little 10A switching power supply that I bought for $10 at a hamfest. I've adjusted the float voltage to 14V, and the battery lasts for at least 3 years. The key is to carefully set the float voltage so that it doesn't overcharge the battery. 73, Jim K9YC ______________________________________________________________ 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
