generally you will seldom see max current at max voltage, certainly not on initial connection on a reasonably large AH (100+) reasonably discharged battery. On a reasonably discharged battery the converter starts charging as a constant current device with a current limit, 40, 50 60 or more amps and the voltage at the battery will rise to whatever is needed to support that level of current. Often this initial voltage is in the 13V range. as the battery charges up most of the converters can't hold max current as the approach the max voltage and current drops as the voltage rises to near the constant voltage threshold and they go into a constant voltage mode, 14.x V which is what the battery wants to finish charge.
As an example, I have a bank of 4 T-125's. with them near 50 percent discharged I can hit them with my PD45A unit in the panel and my 60A unit in thge pass through. Initial current will often be in the 110A range, but the voltage will still be in the low 13V range initially. It takes another hour or so before voltage starts to rise much. I would guess current would exceed 200A to get initial voltage anywhere near 14V initially.
That said the OP is one of the very very few that I've know that was able to get the WFCO into the constant current mode. most I've seen almost immediately drop into the 13.6 constant voltage mode. PD, Iota etc. behave much better.
Iota seems to be one of the best that is able to hold the constant current mode to near the 14.X constant voltage mode.
