jinx'd Posted July 21, 2019 Report Share Posted July 21, 2019 DNA75c. can this chip be used at 75W ? and I thought I remembered reading something about it have a boost to 100w, what's up with this ? thanx Link to comment Share on other sites More sharing options...
VapingBad Posted July 21, 2019 Report Share Posted July 21, 2019 Yes and yes, the boost is in the latest international firmware and only for the initial art of the puff. Link to comment Share on other sites More sharing options...
jinx'd Posted July 22, 2019 Author Report Share Posted July 22, 2019 ok, that's what I thought on both counts. the reason I ask. I have a Visious Ant Primo Titanium 26650. when using it at 50w, the battery cap gets momentarily hot, enough to startle. VA says this normal ! I'm like, NO, ITS NOT! but it seems to be for this mod. as the cap was poorly designed. VA and the guy I got it from tell me to run it at 40w and high resistance coil = bull chit. I am thinking of a fix. otherwise it is what it is. Link to comment Share on other sites More sharing options...
jinx'd Posted July 22, 2019 Author Report Share Posted July 22, 2019 oh. if it says "watt boost" in the settings, then it has the firmware for it ? Link to comment Share on other sites More sharing options...
dwcraig1 Posted July 22, 2019 Report Share Posted July 22, 2019 I have a VA 21700 DNA75C Spade, the battery cap and it's threads in the mod get oxidized quite easily. I was cleaning them with alcohol and they would oxidize rather quickly again. A couple of days ago when I cleaned the I applied a tiny amount of Noalox to the mods threads. It's too soon to know if this is going to work out but I suspect it will. Take note as to if for sure it's the battery cap and not the battery that's getting hot. A 26650 just isn't powerful enough for 100 watts, a 30 amp continuous 18560 or 2xxxx would be required. For sure it sounds like high resistance at the battery cap.

jinx'd Posted July 22, 2019 Author Report Share Posted July 22, 2019 this can is not threaded, it is push and turn. the battery does not get hot at all. I took a good hit, cap was hot. I took out the battery in like 1 second, and it was room temp right on the contact. I am not a battery pro at all. but this battery is 40+ amp =seems plenty. but what do I know. and I don't need to vape at 75w, mostly 55-60. other than the heat the mod works just fine.

jinx'd Posted July 22, 2019 Author Report Share Posted July 22, 2019 ok, I just cleaned where the cap touchs the bottom, it was dirty. it better now, but not good. perhaps good enough, I will have to use it more to see. one thing I have noticed. the batt neg is convex, the cap contact is flat = very little contact.

dwcraig1 Posted July 22, 2019 Report Share Posted July 22, 2019 clean the ramps on the side of the cap and the corresponding areas of the mod. Did this problem start as soon as you received the mod or was it over time? 1 Link to comment Share on other sites More sharing options...

Actually Mooch currently does not even have any 26650 recommendations at all. And IMHO in your case I'd choose higher amperage over mAh, from a trusted store. 12 hours ago, jinx'd said: oh. if it says "watt boost" in the settings, then it has the firmware for it ? Not necessarily, but probably. Check your theme or 'Device Monitor' for the Firmware info. You're looking for 'INT' Link to comment Share on other sites More sharing options...

I know I am the 2nd owner, I know the 1st owner well, online at least. and I may be the 3rd, or more, who really knows. I wonder if VA would tell me who they sold it to, hmmm.

Check your theme or 'Device Monitor' for the Firmware info. You're looking for 'INT' the battery is convex, so only a very small contact is made, I can see it. I have a lathe, so I made the contact on the cap concave.. also, I don't "know" how the copper contact is attached to the cap. if they didn't do it right = high resistance = high heat. I am thinking to silver solder around the outside. Mooch, yeah, I know = fakes. …. ok, so, I can run this mod with a known good 18650 ? I can make a sleeve very easy. ok, I will check soon. thanx Link to comment Share on other sites More sharing options...

jinx'd Posted July 23, 2019 Author Report Share Posted July 23, 2019 ok, I just tried it. still gets hot. but, I loosed the cap just as little, and it didn't get hot. but I still have to test it some more. Link to comment Share on other sites More sharing options...
dwcraig1 Posted July 23, 2019 Report Share Posted July 23, 2019 Is there enough pressure against the battery to make a good connection? You might try adding a thin piece of copper between the cap and cell negative as a shim just to see if that makes any difference. Link to comment Share on other sites More sharing options...

I think there may be a bure or something in there. Link to comment Share on other sites More sharing options...

dwcraig1 Posted July 23, 2019 Report Share Posted July 23, 2019 If you have nothing copper to use a small disc cut from a disposable aluminum pie pan would be good enough to experiment with. Link to comment Share on other sites More sharing options...
jinx'd Posted October 22, 2019 Author Report Share Posted October 22, 2019 update. i now also have a Primo Titanium 21650. it does the same thing. i heard that Titanium is a poor conductor. that may be it. Link to comment Share on other sites More sharing options...
