It seems all sizes of Iota are 3.6 inches or below in height.
I am a little confused about the pendants and whether they included IQ4 or charge wizards are required for 14.4+ or just a bell and whistle and light for remote viewing of what stage it is in. I don;t really need a pendant to force boost modes. A button on the controller itself would suffice, and viewing which stage the converter is in, would be easiest by viewing my battery monitor, rather than having a remote pendant somewhere else to get in the way continuously in my Small camperVan.
