Actually, since the converter can do 15.5ish, you only need the DROK for higher voltages than that. EG, for equalizing certain batteries that need over 15.5v or when 15.5 is ok but it is lower than 80F ambient so the equivalent voltage to 15.5 at 80F is higher when you are doing it.
I wish the PowerMax went to a higher voltage, then you wouldn't need the DROK. I don't know why they put the limit there. The lower limit of the knob on the adjustable goes way below anything that would be useful on a 12v battery (11v or whatever yours does) So you'd think the same amount of knob turn could be better placed in a higher range.
That's true, but the other thing I like about the DROK is that it lets me charge at a selected amperage. I found that if I want to charge at a certain rate, like 10-13% of C, without the DROK, I was constantly having to adjust the PowerMax.
