Replacing my Converter/Charger - Help
Hi Guys/Gals I have a 25' Weekend Warrior toy hauler and last week in Baja my my Iota DSL-30 converter/charger stopped working I bought a PowerMax PM4 100A converter/charger to replace it I was thi...

I got 14.4v from the charger and 14.2v at the battery.
Is that good enough voltage drop?
So a 0.2V drop...at what charge current?
That was bulk mode so 70 amps?
I don't know
It's now in regular mode 13.6 and I still have that.2v difference
Bulk mode (or any mode) would just max out at 70A or thereabout, in theory, before the converter's current limiting cuts the voltage down. In practice it's not quite that precise; often they're limited as much by power as by actively limiting the current.
If the batteries were nearly charged, the 14.4V or whatever your converter puts out could only put a few amperes of charge current through the battery. If they are discharged, it could be a whole lot more current. 0.2V drop at 5A isn't great, but at 40A it would be perfectly acceptable. (This is, of course, a practical application of Ohm's law.)
