Here I found it.

Oh, "since my WFCO is 55 amps", turns out to mean nothing in real life. I hooked my WFCO 55 direct with 2' cables to my half-discharged batteries as a test. It did 43 amps for about 3 seconds, was in the 20's in under a minute, and upper teens within a handful of minutes. The WFCO can only supply 55A at volts in the low 13s. So it will supply it for 12v operation, but not for battery charging. The output falls drastically at battery charging voltages. There is an output curve graph in the owners manual.
