[Elecraft] K3/100 - Battery - A&A Engineering 5 Amp Smart Charger

[Paul at N4LCD.com]

If I connect a K3/100, a 2 meter rig, a 140 Amp Hour deep discharge 
battery, and the A&A Engineering 5 Amp Smart Charger, all in 
parallel, my understanding is that it would work fine.

The key here is that the A&A Engineering Smart Charger is already 
protected against becoming a load if it's off, other than the 175 
microAmps they mention on their site.

Is all this correct?
