grab a hydrometer and measure SG. If they are good, all the cells should have similar SG in the 1.26-1.28 range. Don't know what the inital SG is on crowns,
If ALL the cells are low but similar, it ain't charged yet. hook up the charger and monitor SG and see if it keeps climbing.
The WFCO isn't known for going into bulk mode charging and 13.6 never really gets the batteries to full charge, they need a period of time in the 14.5V range.
And since it often doesn't get into bulk mode, it will take a LONG time to bring a set of 4 GC to near full charge at 13.6, maybe 4-5 days. your only charging at 15A or so and you have 500-600AH of fully discharged batteries.
If one or more cells is more than about 0.1 lower than the others you may have a bad cell. keep charging and see if it comes up
