[Elecraft] K2 on 160m with battery power?

Thanks for the reply Pierre

My K2 draws around 2 Amps for 10 Watts into a 50 Ohm dummy load on 160 m,
provided the supply is more than 13 volts. When on battery power the
situation is pretty hopeless as far as portable operation on 160 m is
concerned. My Hi Cur setting is 2.5 Amps and should be sufficient for most
purposes, especially when running from the internal battery.
