VapingDragon Posted August 18, 2016 Author Report Share Posted August 18, 2016 I have a Therion DNA75 and sporadically I get low battery with in a short times use. When this happens one battery will be fully charged or close like 4.18v and the other cell will be drained to around 3.4v. The mod will not power on with a single cell in it so I'm very confused as to what's going on. Anyone have an idea what the issue maybe? Link to comment Share on other sites More sharing options...
retird Posted August 18, 2016 Report Share Posted August 18, 2016 Sounds like the parallel battery sled is only giving power from one battery. When you tried to power the device with one battery did you try this one battery in each battery slots and see if it would fire?? Link to comment Share on other sites More sharing options...
VapingDragon Posted August 19, 2016 Author Report Share Posted August 19, 2016 Double checking i was wrong. The mod will power on with one cell. Still not sure why some times one cell wont drain. Link to comment Share on other sites More sharing options...
retird Posted August 19, 2016 Report Share Posted August 19, 2016 1. Poor installation of the batteries.2. Poor connection of the batteries.3. Poor wiring of the battery sled.4 Defective battery posts on the battery sled.5. Dirty contacts of the battery +/_.6. Dirty contacts on the battery sled +/_.Were the batteries a "married" set. Always used as a pair thus charged and discharged as a set? Link to comment Share on other sites More sharing options...
yoseff Posted August 19, 2016 Report Share Posted August 19, 2016 Therion have a mechanical reverse battery protection. May be that the reason. Take a look in the positive poles and you will see some plastic around them to prevent a negative pole making contact. Maybe that plastic is protruding too much in one of them.I am tempted to cut that off, as it damages the wrapping on the batteries. Link to comment Share on other sites More sharing options...
Swainesmatee Posted August 23, 2016 Report Share Posted August 23, 2016 I'm not trying to knock your device and this has nothing to do with your question but I just want to say I'm glad that I tried one of these devices out in person because it looks beautiful and so solid in the pictures and then when you feel it in your hand the buttons are mushy they don't line up well stick a little bit in some instances. Compared to the hcigar vt75 it feels so much less solid and that's not saying much considering its cigar doesn't put out the best devices in the world. All I know is that I put that money towards something else. The DNA 75 was not designed for two batteries otherwise it would have reverse polarity protection built-in. And when I saw the size of it it just made me wonder why would I have a device that size but I can get a hundred thirty-three or 200 Watts out of it.. It's a really good looking device in the pictures when you feel in person he really has a cheap plastic feel. I'm not surprised that DNA chip is not charging / discharging your cells evenly. And one brain fart you insert your batteries backwards and boom your device is dead. Good luck with everything I'm only writing this for anyone considering purchasing one that it definitely does not feel as good as it looks. You're great at taking fancy pictures Link to comment Share on other sites More sharing options...
ear3y3s Posted September 1, 2016 Report Share Posted September 1, 2016 if its sporadic draining on one particular battery bay... check the wiring solder point on the battery contacts for that sled. its probably a loose solder job? Link to comment Share on other sites More sharing options...
arsacane Posted September 2, 2016 Report Share Posted September 2, 2016 The Therion is a wonderful device but I don't like the battery tray; these mechanical reverse battery protection is a pain (same thing goes for wismec's Reuleaux DNA200). Some batteries do not seem to make good contact (I had problems with a re-wrapped battery; the shrink tube that I have seems to be a tiny fraction thicker than the original one) and since the cells are in parallel there is no way to tell.

You're great at taking fancy picturesSorry, but i disagree with your points. I own one therion, and the device is solid, not seeming "cheap" in any way. The only complain i have from it is the reverse battery protection that is not good, but i will correct it soon.In regard to size, with 2 18650 i suppose its hard to do it much smaller.Maybe you did put your hands on a clone or a not so good unit? Mine has been flawless. Link to comment Share on other sites More sharing options...

But i believe that we are just talking about a less good unit. One that escaped quality control. I have two Lost Vape devices (Efusion Duo and Therion) and they look well built and solid.

ed0x Posted November 26, 2016 Report Share Posted November 26, 2016 I have had my therion for about 4 months and this issue of only one battery in the sled discharging started. Real bummer can't handle the builds I had on there with the amperage cut in half. I sent an email to the wholesale asking information on the warranty just been waiting for some sort of response.

MadHatter77 Posted January 7, 2017 Report Share Posted January 7, 2017 Oddly enough, i'm having the same issue. I've used a multi-meter to test continuity from + to + contacts and - to- contacts. Continuity is good. So I would assume, that rules out a bad solder or loose wire. I did manage to take the MOD apart a little. The board wires are soldered to the inner most contacts and there's a small jumper the goes to the outer contacts of the battery sled. Link to comment Share on other sites More sharing options...
ed0x Posted January 7, 2017 Report Share Posted January 7, 2017 This site almost looked fake to me but ended up sending it to http://www.lostvaperepaircenter.com/ for the warrenty repair haven't heard anything back yet and its almost been a month.

Pajomota Posted January 16, 2017 Report Share Posted January 16, 2017 I have noticed this issue yesterday for the first time in 6 months. I'm trying now with a new set of batteries. Maybe the positive contact of batery has gone inside a little and because of the mech. protection it does not make contact. will it be possible to cut the "protection plastic?.. thanks.

Also many times i charge batteries inside it, so i didn't bother to do it.About safety... As long as you don't reverse any of the batteries, seems ok to me Link to comment Share on other sites More sharing options...

Canislupus Posted April 5, 2017 Report Share Posted April 5, 2017 I know this is an older thread, but I will share what I found on my Therion. It too was only discharging one battery. Upon investigating it (looking carefully) I found the inner upper battery contact was pushed in and not making contact with the battery. I tried to remove the sled etc, but had difficulty, so I very carefully applied a dollop of solder to the upper contact. This built it up enough that a connection was again possible. Needed to score the surface of contact first, then heat contact sufficiently for solder to Flow onto it nicely. If enough heat is not applied, you will get a chunk of solder that will chip off very easily. Hope that helps someone. Link to comment Share on other sites More sharing options...
ed0x Posted April 5, 2017 Report Share Posted April 5, 2017 In the end I sent mine in for service to the lost vapes repair center in Ohio. It was barely within the 6 month warrenty and was fixed for free just paid to have it sent out. On a side note repairs outside of warrenty are $35 so I was prepared to pay that cause I'm pretty sure by the time it got there 6 months had passed. It came back in a little over a month working great. From what I hear its one guy doing all the repairs so be patient and feel free to email him for an update past 30 days.

popoyj Posted April 6, 2017 Report Share Posted April 6, 2017 I have the same problem.....when you put 2 batteries it only use one slot (I think the inner slot)...but I can use it by putting 1 battery on either on of the slot...example I put 1 batt on slot one it will fire... I put it on slot two it will also fire.... but put them both.. only the inner slot will be used.... Link to comment Share on other sites More sharing options...
