Thanks Jim. I'll take a look at that one. I wasn't thinking about mobile operating but the KX2 would run directly off the car battery. Rather, I was thinking of what my possibilities were when I spend days away from an AC outlet..The Samlex inverter you show in your presentation clearly needs a L

For further clarification: The Lithium Ion battery packs supplied by Elecraft are 11.1v, 2.6Ah. I think the Tenergy charger supplied by Elecraft charges at 2000mA 73, Yngvi TF3Y On Sun, Apr 15, 2018 at 2:51 PM, Mike Furrey wrote: > I am not sure what kind (size, shape) of Li batteries are in th

I am not sure what kind (size, shape) of Li batteries are in the KX2 but as a caver I use 18650 Li batteries in my lights. I have found the Nitecore D4 intelligent charger that works on both 120 VAC and 13 VDC that does a good job of charging a variety of Li and Ni-cad batteries either at home o

You can purchase a small Inverter ( probably least expensive) or Tenergy makes 12VDc powered chargers. -- Sent from: http://elecraft.365791.n2.nabble.com/ __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft H
