on a slightly whimsical, side note.....is there provision for bottom of the range scalars of sub zero temperatures.....you know just in case someone wants to vape accurately in the frozen tundra ?
Last winter, weren't there some people complaining that their DNA40s didn't work correctly if they were exposed to really low temperatures for a while?

Absolute max is 16v.
Perfect, thank you!John said:The easiest way around that is set up a three resistor divider to generate "cell" voltages for the balancer to see. You can also disable battery monitoring entirely, which is for fixed installations only, but is useful if you're building the board into a research smoking machine, or something like that.
Yep, I'd plan to turn battery monitoring off. -
Spec says 12.6V maximum input voltage. That's a 3S Lithium Ion. Specs also imply you can run the DNA200 from a 12V power supply or a lead-acid battery. Depending on their exact chemistry, fully charged lead-acid batteries can exceed 12.6V by a bit, and you're certainly going to exceed that while charging them. So I'd like to ask:
What's the Absolute Maximum Input Voltage, and what will happen if it's exceeded?
The places I spend the most time are at one of my desks and in my car. So I'm toying with the idea of making a pass-through mod (a squonker, of course!) that dispenses with the whole 3S battery thing and runs directly from a "12V" power supply, but many of them actually output more like 13.8V (to emulate a car that's running) and of course in an actual car, we might see something as high as 14-15V.
Am I gonna blow up my boards if I attempt this? -
Excellent of Evolv to do this.
DNA50/60/70?

Yep, please make a smaller board that runs from a single cell, but includes most the software features of the 200.
50 watts will satisfy 90+ percent of vapers for a long time to come, and more than a few of us would like to build a reasonably sized squonk mod, something that the current DNA200 form factor doesn't lend itself to very readily.
