Need a quick answer from the battery guru's

If you have a RV manufactured within the last 10 yrs you most likely will have a more modern converter which uses a switching power supply. These converters can supply the FULL rated amperage into the battery.

Unless it's a WFCO converter, then odds are it will never go into boost mode.

Actually there has been some folk that simply upgraded the wire size and or shortened the distance between the WFCO converter and battery and were successful at attaining boost mode. But with stock wire and or distance you are most likely correct.

I myself have a PD9160 with charge wizard and have no issues with all three modes.

yes, a few have been successful with the WFCO's, but most have not. Way to many TT manufacturers have a long enough distance between the converter and batteries that getting a WFCO to work is an excercise im futility regardless of what wire you may try, myself included.

BTW, in the last month I've run across 3 campers who were scratching there heads because after running a charger ALL day long, the cheap battery indicator showed 1 light less than full charge. Guess what, ALL 3 had the WFCO, and digging out my handy dandy clamp on ammeter and fluke voltmeter the reason was obvious. Battery voltage 13.4-13.6V (not in bulk mode) and charging current 10A or so. Only marginally better than the typical 6A auto store charger. Trying to get a pair of GC or big 12V charged like that ain't gonna happen anytime soon.

After our first weekend out, I tossed the WFCO and replaced it with a PD drop in and a PD 60A in the pass through. that way if needed I can parallel them and my honda 2000's and stuff 100+A into my bank of 4 GC batteries.

My advice is that unless you like to tinker, toss the WFCO and go with a PD, Iota, or Powermax Boondocker. Or, if your cash strapped, get one of the B&D 40A vectors, I have one to "loan" to those in trouble and equalize/top off my batteries. A very good charger.
