ON a NEW WFCO 8955, at what voltage should

My WhiffCo makes an excellent 55-amp 13.6 volt FIXED power supply. For floating I rigged up a pair of $2.95 power bricks (paralleled) and two eBay voltage buckers @ $6.00 ea. Takes me a whole ten seconds to re-adjust voltage for temps twice a year.

I like journeyman's answer. Separates the wheat from the chaff.
