Although I just got Cartel Revenant I just ordered this puppy. I love the snake skin door!

I bought the same beautiful Therion DNA 166, but it is defective. It does not detect power in the batteries and displays the "check batteries" message. It will not fire. Oddly enough, I have EXACTLY the same problem with a recently purchased HCigar DNA 167. (Both mods use the DNA 250 chip, derated down to 167 watts because the mods use only two 18650 batteries.) I've requested return instructions for both.

On the other hand, I've had zero problems with a Therion DNA 75 that I've been using for a couple of months, and zero problems with a different Therion DNA 166 (purple ostrich battery door) that I just received today.

Have you checked in Escribe to make sure you have selected 2 battery vs 3?

    Well if anyone else ever has the same problem I posted about, I "fixed" it by doing what everyone says you should never do with these mods: I locked the resistance. My vape experience has been great for the past 9 days.
    By locking the resistance the mod does not 'refine' the resistance, and usually done when you have a jangy build or atomizer (that was attached at room temperature). So you end up with more consistency, but less accuracy.

    Love the way that mod looks, I don't have a DNA mod yet but I think maybe later this year I will be going to lost vape for one..

    Lost Vape makes nice stuff. If you are thinking about a 166 Therion later in the year, you might want to hold up and see if the DNA 250c (166 with 2 batteries) Therion drops. Not for the color screen but for the ability to do far more on the mod without running into eScribe all the time, and lots more customization and themes down to even which features you do or do not want to adjust without eScribe. The DNA 75c is out and LV is using it in 2 mods, a Therion version and a Paranormal version which has easy to replace side panels and the batteries inserted through a battery door on the bottom. Personally I'd stay with the Therion as I like the interchangeable leather/snake/exotic battery doors. I do get it's way easier to insert the batteries from the bottom without having to pry them out, but IMO it just isn't as aesthetically pleasing as the Therion.

    While it was working and plugged in, did you by any chance remove/replace the batteries?
    It's not something I'd worry about doing, so I took no note of whether or not I did that. However, the Therion was defective before I ever connected it, while the HCigar worked for a short while before it stopped working.

    I would certainly return them, but out of curiosity, what batteries are you using, and have you cycled them through other mods to see if they are both behaving properly?
    That's the first thing I did. The batteries are good. They're Samsung INR 18650 25R5 batteries.

    It's certainly possible with my sub-par building ability but I doubt every single coil I built was bad. All of my RTAs work fine on my eLeaf iPower 80 which provided ohm readings in line with my ohm meter.

    If FastTech ever ships the other Therion 166 I ordered a month ago and it works fine, then I'll know for sure if there's something wrong with my current Therion. In the meantime, I have no desire to try out different things in escribe. I'll take less accuracy for the great vape I've been getting.

    @Herrick Let me rephrase. When you initially fire up a TC coil and NOT lock the resistance, while the coil is cooling down, 'refinement' kicks in and will lower that value you saw to what it would be at 70F.

    No one can argue with this, but regarding accuracy, that means your 'Mod resistance' and 'Thermals' should have been set by the Manufacturer, and not just left at their default Evolv values.

    Having said all that, I do believe your new mod will exhibit the same behaviour of the resistance lowering when a TC coil cools

    Is this a common thing with Therion 166 mods? I got my current mod from a US seller and the other one has been ordered from FastTech. Other than locking the resistance is there a way to counteract the resistance change?

    This is the normal behaviour for all the current DNA boards if you do not lock the resistance while trying to use TC. If you vape a TC coil with straight watts, it will display the current live/actual ohms.

    There is a board temperature sensor. If your thermal characteristics (heating and cooling) and mod resistance is set, this refinement calculates the current ambient temperature, and will also calculate the cold ohm's at 70F. So as the ambient temp changes, the resistance will ever so slightly change for that 70F calculation, hence the accuracy of the temperature selected.

    Nothing wrong at all with consistency (locking the ohms). According to ecigstats in my over 200k puffs, and 52% in TC, I've only needed to lock my resistance on one atty with a shoddy (plating half gone) 510 pin. Up here in the Great white North, I'll also purposely lock in the winter going from indoors to outdoor activity

    Locking the resistance was never part of their original thinking, and only added after user requests.

    Is there a way to get the Therion to match the cold ohm readings of my ohm meter & my other mod?

    @Herrick Sure, just go into Atomizer Analyzer, and set/lock it there. No way I know how to do this automagically.

    So you trust both your ohm meter and other mod more than you trust this board?

    I do but only because of the subpar vape I get on the Therion without locking the resistance. I thought something was wrong with it because I get a much better vape on my Eleaf iPower 80. I mean, when every tank vapes poorly on the Therion but good on the Eleaf it seems more likely that there's something not quite right about the Therion. But then again I don't know much about DNA boards.

    If the Therion is producing the more accurate reading but producing a subpar vape experience, what do you suggest I do?
