I have a WFCO-8955 (55 amp) that absolutely will not go into bulk mode even though it’s a 3 stage converter. Not sure if it’s inadequate wiring or an inadequate converter. It’s always 13.6-13.8 no matter the state of charge of the batteries. What I’d like to know is how many amps is it putting out in this mode. And don’t tell me 55 because we all know that ain’t possible! ??
I've measured close to a dozen WFCO's with an output voltage of 13.6V or so, and it's like most any charger hooked to a battery >50% charged that has an output voltage of 13.6V or so.
15A or so is all it's putting out. May be as low as 10A, might be as high as 20A.
Doesn't seem to matter if it is one 12V, a pair of 12V, a pair of GC2's or four GC2's. clip on DC hall device current probe is in the 15A or so range.
