RV Voltages too high while charging
I have a problem and have been wrapping my head around this for a few days. I have four 100w Solar panels, and a Morningstar RJ-45 programmable charge controller wired to batteries. I have Four In...

Is that to be considered "recent"? Not sure. All I know is "multi-stage charging" has been around a lot longer than I've been RV'ing. I admit I am not at all familiar with linear type chargers, or single voltage chargers, but I can't imagine flooded lead acid battery technology has changed a whole lot.
Anyway, I doubt any of this has to do with establishing proper charging voltages. All I know is what I've seen first hand. I do not cycle my bank deeply, nor do I let it sit in a discharged state or any real length of time. But I am seeing the effects of regular over-charging. Self discharge has increased by leaps and bounds, and resting ocv's have dropped noticeably. I doubt anyone recommending I charge at 15.3v on a regular basis is going to reach deep into their pockets and cough up the near $700 to replace my bank.
