Yes the trick is the maximum voltage is 6v. So as long as you are not running at higher than that or 28a, whatever your coil resistance is shouldn't matter much.
I don't really understand your explanation here. I do understand the technical of battery draw and the math is no issue. What I don't get is why you'd say 6v is the "trick" and then state 28 amps is the limit. And how does the coil not matter? You mean functionally it doesn't ? Cuz who is really pulling 28a?
Not picking - genuinely curious about the train if bought leading to that statement. Maybe I'm missing something obvious. From what you're saying if you drop a .05 temp control build in there with a 28a limit you're not putting much power to it. So a lot of battery flashing is going to happen. I'm too lazy to do the math right now (haven't slept) but is really Low power. So the coil matters a lot if you like high power and temp control. Or does he dna75 die something in Reno control mode regarding power limits and such. Like allow split second bursting of much higher draws. Etc?
My anemic vape issue did variation number 2 last night. Cold
tank mounted and read at .83. Needed 575F to get a defer vape.
tank slept and came back still at .83. But needed only 440F for the same vape second go round.
So the temp variation issue ain't always accompanied by resistance changes. No the resistance isn't locked.
The sdna looks really nice with the c1 imo.
