My local B&M demonstrated the Istick to me today and the reason it has no step down function is the fact that you can set it to as low as 2 volts
I just want to clarify this for anyone finding the thread. In this case, as is often the case with B&M's: they are wrong and don't fully understand what they are selling.
The istick will click down under 4V on the screen, but it doesn't actually output under ~4.1V. The electronics have to be able to lower the voltage it gets from the battery. If it can't, it'll just output the ~4V until the battery is so low that what it's getting is 3.7V or such.
Again, it may say 3.3V, or 3.7V -- but it'll always be 4.1V or higher -- and does even weirder things at other voltages. Which is OK if your ohms are higher or your tank needs the extra oomph, but causes problems if you need lower voltages or accuracy at lower voltages.
For reference, you can see it here, at just after 23:20 when he shows the voltage charts (here's where it should be, here's where it is, etc.):

And there's a post by another member here, along with a chart showing the voltages where it's regulated and where it isn't:

With that, I return you to what Caprilli's one-person rendition of
