The OP hasn't mentioned just how far down his batteries were discharged.
I put how far to the best of my knowledge, 75% amp hour wise although I know they were not fully charged, and resting voltage of 12.5. I think the 75% may actually be closer to 65% since the Trimetric only knows how to count up or down from charged.

Do you have the IQ4 module with your Iota? You need that for 3 stage charging.
I do not, for now I think I can do without the 3 stage operation since I want to only do bulk and absorption with the DLS-45 and finish the absorption and float with the PV and SS controller.
