Has anybody found a fix for this yet as my second Therion BF has just started draining batteries. It has killed one battery altogether by draining it from 50% to dead overnight, Im sure there should be something in place to stop it doing that. I cant believe how flaky the 75c board is when compared to the older versions. I have found the 75c to be nothing but problems. out of the 4 75c devices I have bought none of them are in regular use because they are unreliable and now with the battery draining issue they are potentially dangerous.

My Therion BF 75c has just started draining batteries too. Has anybody got a fix for it yet?

I don't doubt that is true, However I can only speak from experience. I own quite a few DNA devices and have never had a problem with any of them until the 75C. My first one was reading the resistance too low, it still does and when I try and use that mod I am just guessing at temperature because it reads a different resistance to the dozen or so older type DNA mods I have. If I do decide to use it I then have it nag me throughout the day, constantly asking if I have changed the coil. I have run the case analyser countless times before you tell me I need to do that. That was never a problem with the older DNA boards. I bought 2 of the Therion BF 75C's and they now read the resistance too high, so once again I am left to guess at what the temperature might be. I have lost confidence in what was widely regarded as being the most accurate device on the market and wont be buying any more. Whether its reading too high or too low it is no longer accurate, Vaping on a 75C has become a chore. I cant rely on being able to pick up my mod and enjoy a vape. So as a result the 75C devices I have bought wont get used.

Its not worth the hassle. Im not getting on with the 75c board and even if I did get one to actually work half as well as the older style DNA boards I wouldn't use it because I have no confidence in it.

Having the exact same problem with my 75c BF. putting a blob of solder on the 510 as shown above didn't change anything (other than invalidating any warranty I may have had). I have come to the conclusion the 75c board just isn't worth the trouble I am having with them. Of the 3 mods using the 75c board I own, not one of them can be relied upon to give an accurate reading. I wont be buying another that's for sure.

Yes if I manually adjust the resistance it feels more like what I would expect it to be like. The device monitor graphs look good and the vape is smooth. The problem with that is as soon as the coil cools a little I get the "new coil" message, which gets annoying after a while.

Using my Therions Therion 75 . Raw 0.499/5 Room temp 73.2F .0028 mod resistance Therion 133. Raw 0.501/2 Room temp 75.36F .006 mod resistance Therion 75BF. Raw 0.498/9 room temp 73.5F .006 mod resistance Therion 75C. Raw 0.464/5 room temp 27.25C .003 mod resistance

Yes I am using sp23. Im using ss316 and on all my other devices the coils read at 0.5 ohms but on the 75c its reading at 0.46 ohms. Not a massive difference maybe, but its enough to take any sort of accuracy out of temp control. I usually vape somewhere between 200 and 220 degrees C but to get anywhere near the same experience on the 75C I have to run at 240 and upwards, which means Im just guessing at the temperature.

The new firmware bundled with the latest escribe version doesn't make any difference to it reading the resistance too low. The release notes say its fixed but it hasn't changed anything. Still reading too low for accurate temp control.

Sorry but when I bought my Mod I expected to use it, Not have it sitting on a shelf for 6 weeks because it cant do the job it was bought to do. Call me old fashioned but I still believe Beta firmware and beta testing should be carried out before the product goes on sale. When did it become the customers job to beta test products they have bought?

No the thermal settings don't make any real difference to it reading the resistance, Its a shame really because I really wanted to use the mod but instead its become a very expensive paperweight. Hopefully Evolve will fix the issue soon.

I have tried the ,csv from Daniel (DJLSB) and it does seem to increase the temperature of the vape a little but now I have no Idea what the actual temperature is, The numbers on the device are no longer an accurate representation. The ohms reading is still way off where it should be according to all my other devices and Im just guessing what temp Im running at. No doubt I will run into similar problems with other wire types too. As it stands I really don't want to use the 75c. I just don't like having to guess and bodge it to get anywhere near a decent vape.

I will try the .csv from Daniel (DJLSB) when I get chance. Hopefully it will make the device a little more useable - even if I have to start using 316L rather than regular 316. Seems silly to spend money on the most accurate device on the market and then have to guess what temp you are running at. Hopefully we will find out whats going on very soon.

Yes I take a cold atty and get different readings on the 75C than all my other devices and my USA ohms meter.

I have had no joy with the case analyser. I ran it again and got the error, so I changed the values myself but its made no difference to it reading the correct cold resistance. Im still having to change the resistance manually to get anything near a decent vape.
