TomEV - thank you for the information. I am running a pair of SLA alarm batteries currently. (Which is why I can kill them with lights & blower in 20 minutes on a cold night). So, yes, I need to reduce the output voltage or suffer the consequences!
SW - it's apparently rated 0 to 6.66A continuous. And a diode was recommended if I am to leave it connected to the 12v battery (see Lee Hart's advice, link below), as well as using the trim features to further reduce output voltage.
Ben - thanks for posting that info! (And congrats on beating me on a parts purchase
)
I also got a couple of detailed replies to this query which I also posted on the EVDL. If anyone wants to read them...

It's not quite as simple as I was hoping. (IE not just hooking up 4 wires and a switch.) Apparently for longevity of the device, I've got to also connect in a "transient voltage suppressor", a Filter capacitor, fuses and misc other stuff. See Lee Hart's reply in particular, if you're interested.
Lee is one of the Yodas of the EVDL, so I will be following that advice so as not to let $20 worth of smoke out of the little box.
