First time to 50% SOC

IOTA did not even get to make a full swing at these batteries before the BD went to work. I think it hit 14.6 at some point and when you saw 14.0 it may have dropped to 14.2 absorption. .2 could be the loss in the wire? Or maybe it was still on the way up in bulk. Or bulk timed out. Hard to pinpoint unless you record battery vs converter voltage every 10 minutes.

Like I mentioned before the IOTA was on the bank for a week. It was in float when I unplugged it and threw the BD on them. That's sort of what I do typically (I use the HF charger for finishing normally). I have left my old Paramode on the bank for a month before just to see if in time the SG would come up. It never got the SG up high enough. As a matter of fact, it came up very little. So little I thought I might have done permanent damage to my bank by letting them sit not fully charged for so long. Thank goodness they were fine but I'm betting they lost a little capacity with that experiment. The IOTA floats basically at the same voltage as the Paramode so I don't know what it would do that's any different than what the Paramode did. Sure, the IOTA has the stirring thing but 15 mins at 14.7V won't work for finish charging (EDIT). It DOES work for destratifying as that's how long I (used to) perform that maintenance item for. 15V for 2-3 hrs does work every time without fail. 3 years so far on these batts with a 1.285 SG. Exact same as new. I'm going to stick to my regimen for now. Look at the bright side, I don't have to do nearly as many equalizings as before but I think that's due to MEX's top charging advice.
