Or use a step-down adjustable voltage regulator from http://dimensionengineering.com/DE-SWADJ3.htm
Popular among the R/C crowd, I've used this regulator (set to 13.0v) for over a year now without any problems to power my K2 from a "older" 4S LiPoly battery (fully charged to 16.4v and a flat operation voltage of 15.6v). The battery has still got a lot of re-charge cycles left so don't want to replace it yet with an A123 battery. Plus, I add fuses for both leads and a crowbar diode for reverse polarity protection. Everything fits in a 2.5" x 1.5" x 1.15" plastic box. Email me directly if you want more information. 73, Guy/N7UN -- View this message in context: http://elecraft.365791.n2.nabble.com/Supply-Voltage-Range-Elecraft-K2-transceiver-tp7179694p7181639.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
