I think the settings are the ranges with the mvp and vv. It's been a while since I measured, so I'm not 100%. So there's a 5volt limit, but also an11 watt limit. For some reason, it will fire a 0.8ohm coil at 2.7ish volts..I don't get that. I think boost mods shouldn't allow you to fire a coil that can't have its voltage adjusted.
I was about to wait around for a dna30 board, but all these other options are coming around.. I think the dna30 is still my best option for standard resistance.
Edit- still has a 3.5amp limit. I do remember that I measured a 0.8ohm piece of wire around 2.78volts.
