[Elecraft] K2/100 and battery

[Goran Hosinsky]

Hi,
I plan to use a 12V 17 Ah gel cel as power suply for my future k2/100.
Calculating with 30% transmission at 20 A, using CW with 50% duty
cycle this should theoretically be good for about 5 hours of on the
air time and with a small linear charger - no hash.

But will this work in practice? Can the K2-100 function on a battery,
the input voltage going down to 10.5 or 11 volt?

One posibillity would be to put 2 12 volts batteries in series and
then use a voltage stabilising circuit to get 13.8V  -  but that would
give me a lot of extra heat.
