12 cells of GC220 50% discharged and not accepting 100-amperes?

Maybe if the setpoint voltage was 13.4 but even at that low voltage I would call it impossible.
I just got back from looking at a system a few miles out of town. The guy has four LTH 208 amp hour GC's and a 12-horsepower Honda engine driving at 4875 JB Leece-Neville alternator. The negative battery stud had loosened (bad rebuilding craftsmanship), and after I had cinced up it and the positive carriage bolts, he fired it off. ONE HUNDRED TWENTY THREE AMPERES, on his e-meter, and verified with my clamp-on ammeter.
I had to wait forty minutes until the regulator reached absorbsion limit then set the voltage up to 14.6. He has a pair of 150 watt panels.
To claim 6 cells of GC batteries cannot take 50-amps is absurd. I'm beginning to wonder...
