[Elecraft] Powering a K3s from a battery?

[Marc Veeneman]

My K3/P3/VGA monitor are happy with power from http://bioennodepot.com/lithium-iron-phosphate-lifepo4-batteries/bioenno-power-12v-40ah-lfp-battery-pvc-blf-1240w.html

It's small enough to lie flat on a shelf with 3.5" clearance with a footprint smaller than my iPad.

My KX3/PX3/KXPA100 run on another identical battery.  These have plenty of capacity to power 100 watts CW for longer than I can stay active.  They start out at 13.2 volts and stay there for hours.  I do use #10 AWG wire, though, to minimize resistive loss.
