I also tried to get that coil higher in wattage, but at 45 watts it was dry hitting too much. Vandy Vape VVC-15 (SS316L) are rated for 35-60w. Hopefully I'll get a chance this weekend to do a build that will be able to handle 60 watts. Anyways I am not seeing any short battery life using a San DNA80C. It looks respectable to me. The battery level bar does drop too fast and it seems to show empty when you have about 40% capacity left. That might be by design, I dunno. And when the battery is really empty and the weak battery shows up on the screen, It keeps firing if you want. But you can tell the wattage is dropping. Yeah thats not my experience. At 35w on the san with a new sony vtc6. I dont have any voltage drop issues. I do max 300 puffs per day and I have to charge it after work which has to be about 150 puffs 1 Link to comment Share on other sites More sharing options...

You might consider completely removing that plate to see that there is no anodiztion interfering with it's connection to the chassis. 1 Link to comment Share on other sites More sharing options...

I wouldn't pop that window out on the Sans. I know what @dwcraig1 sees and Evolv's example probably the board does come out from the window side. But the San's window is smaller and is glued in (and juice proof) and it is framed unlike Evolv's. And there is no way the board can be removed through that opening even if the window was removed. I would not mess with that window on the San. It looks like everything comes out through the other side. On the bottom of the San, see that rectangle on the bottom (picture below)? It looks like there is a screw under it that connects the positive battery connection to the board through that lower wire (picture above). I would not mess with this and find out if you could exchange it at the place you got it. Telling them it has poor battery connections. If that fails, try Evolv by opening up a ticket. If you are stuck fixing it yourself. The ground screws looks like they are on the other side under the panel. If the ground screws doesn't solve it, then it is likely that positive battery connection under that rectangle on the bottom. I can't tell if it is a sticker or a plate. I think it is a plate and a hair dryer should soften the glue to lift it off (hopefully). EDIT: That is a Vaperz Cloud logo on the window.

Now with the .6 coil I'm running it seems weird cause I can easily make it through work vaping heavily at 28w and have battery left until almost end of day. Surely the 7w cant be that much. But i was also running boost at 1 and warmth at 5 before, switched to 0 boost and 3 warmth since then cause you dont need boost for stock coils rly. Will test again once I get my hands on some 35w coils. Edited July 28 by intel Link to comment Share on other sites More sharing options...

That's why I'm not using the San anymore while I'm here and only the blaze now since it seems to be more battery efficient. Does the battery drain without using the device? Because the San's positive battery post is really close to ground (see picture). They say e-liquid isn't conductive. But VG and PG absorbs moisture and then it becomes conductive. And if e-liquid was there, it would likely drain the battery. 1 Link to comment Share on other sites More sharing options...

So I opened the mod from the panel side and was able to access and tighten all the screws; seems to have helped a bit with getting more juice out of the battery, as the puff count is now around 150. but I'm still getting these weird spikes nd voltage drops when I vape on it, what do you think ?

Havnt noticed much battery drain when not using, also I have never had liquid down there so far, I keep an eye on it often as you need to change the batteries all the time :D Link to comment Share on other sites More sharing options...

dwcraig1 Posted July 30 Report Share Posted July 30 That's 3.72v on the voltage drop with full charged cell, you should expect yours to be about the same. Were the 3 screws on the top plate in need of tightening. Did any screws appear loose.? Link to comment Share on other sites More sharing options...

Still the ones i used was around 70% full. nothing was lose, i just snugged everything. Link to comment Share on other sites More sharing options...
dwcraig1 Posted July 30 Report Share Posted July 30 I don't understand those squiggly lines at the beginning of charging. As far as voltage drop if yours looks comparable to mine then you good to go for that. I plugged mine in without a cell installed, it looked wild but still not like yours.

The only time I've seen those weird spikes was vaping on PnP or GTX or an RBA using Nichrome coils in both straight watts or Replay. The watts looked like a jigsaw blade and I could not feel any difference in the puff. It was strictly on the display. Link to comment Share on other sites More sharing options...

Dieseljesus Posted August 1 Report Share Posted August 1 We have contacted Vaperz Cloud now to see what they say and if I understand @EagleRock correctly the support at Vaperz Cloud reported back that they got atleast one customer that had these problems. Now let's see how this evolves 1 Link to comment Share on other sites More sharing options...

Vaperz Cloud have been ghosting me and @EagleRock which is sad. Both me and him sent mails to the UK sales and support contact and they have been awesome before but now, just silent. To be honest, the San with Dna80 is a disappointment that feels more and more useless every day and I'd rather use something like my Pulse V2 with one battery per workday rather than the San with 3-6 batteries... It's just ridiculous 1 Link to comment Share on other sites More sharing options...

ZERBIsvapo Posted Saturday at 08:08 AM Report Share Posted Saturday at 08:08 AM Guys, I have a Stubby 18650 X-ray (NOT DNA), and I had the same problem. (at 50% battery the mod says "low battery", low voltage and wattage gap after 80%. I also have the DNA splatter edition and I heard that many people have the same issue even on this model. After I cleaned everything, tightened every screw, (spanned many and drilled to remove them ), I changed the board and nothing! I don't know were I found the strength to keep on trying but finally I understood the reason of the problem! The problem is that on some items after some months of vaping the roller upside the negative side of the battery need to be tightened more and more. I had thought about that but I was worried to ruin the mod (breaking the up plate). The reality is that the battery need to be very grasped in the slot (don't stop tightening until the roll is completely blocked! if you don't have the nails use something od plastic to spin more strong). My mod was terrible, it didn't fire after 70%! and the power was 20W when I was putting 40W ! I have also sanded al the contacts of the board and the plate, but the situation changed completely after I tightened more and more the battery's roll. Vape on!
