Coils

[Topwater Elvis]

The nautilus bvc replaceable atomizer head has a vertical coil surrounded by wicking material, there is no wicking material inside of a nautilus coil.
The wicking material surrounds the outside of the coil and fills the void between the coil and the body of the head.

Aspire prints the recommended voltage range right on the side of each replacement atomizer head.
1.8Ω = 4.2v ~ 5v = 9.8w ~ 13.8w
1.6Ω = 3.3v ~ 4.2v = 6.8w ~ 11w
Using them below the recommended low does reduce head life due to coil gunking & can cause all sorts of problems regardless of what liquid is used.
vaping colored, heavily flavored, dark and especially sweet liquids will further reduce head life.
I'd recommend trying the 1.6Ω heads if you like to vape below 9.5ish watts.

Many folks exceed the recommended power range using all varieties of replaceable atomizer head type delivery devices without issues.

Mine/yours must be old or you/I have clones mine I'd say 1.6Ohm 3-4.2v 1.8Ohm 3-5v. No mention of watts on them but 7w would be well above 3v. I have never hit the high end of a recommended watt/volt before myself... usually low/middle is my sweet spot. 3.4v or 6-6.5w on 1.8ohm for me, above 4v and it gets nasty to me.

Welcome and glad you joined.

@Completely Average Man, i couldn't agree with you more. Tons of hyperbole and misinformation in this thread. Although I use the BVC 1.8 coils, and have the wattage set at 13. I DIY my own 70VG/30PG juice with no sweetener. Coils easily last 3 weeks.

@LamaMania Ensure your coils are authentic.

 

[Gramdogg]

Yeah, sorry TC would be different. 50/50 isn't to thick though, just thought it was kind of mean to criticise his watts and suggest an extremely high voltage and amount of juice to run through them. Average user and me personally 7-10 days with high VG at the same wattage he uses is normal for most coils. SS, Ti, Ni, Claptons maybe 1 month or more. Nothing "wrong" with it as suggested. Everyone is different. Before rebuilding I'd use the same wire longer then that but I'd still rewick around the same time... sometimes wick is clean and sometimes its black inside where the kanthal coil touches. Depends on the flavour juice I'm running not on how I vape.

 

[Gramdogg]

Upon further reseach as I suspected they did change them, they have larger wick holes to support higher Voltage. Was over a year ago. Mine are old coil heads I just rebuilt so assuming the ones he purchases are old stock as well. I'll have to look for a pack myself lol. These ones over 4v with my 70VG I get dry hits sometimes. Guess you will know by what volt they recommend if its old or "new".

 

[Topwater Elvis]

The OP asked about nautilus replacement heads.
This thread isn't about rebuildable's or your confusion with rebuildables vs a nautilus replacement head.

The nautilus heads are very difficult to rebuild with even so so results.
Cleaning nautilus heads isn't recommend and rarely does any good at all.
Without being able to remove & replace the wicking material there is no way to dry burn to remove coil gunk. Soaking in PGA usually removes very little & usually causes the loosened gunk to clog the wicking material very rapidly.

You seem determined to hijack the OP's thread & turn it into all about you & anything but what the OP asked about.

4.2v / 9.8w is the manufacturers suggested low for the 1.8Ω heads.
Sure you can use lower power to suit individual preference but that comes with side effects, like reduced head life.
If a person likes to vape below 9.5 ish watts I'd suggest trying the 1.6Ω nautilus heads.

Obviously you’ve been using knockoff/counterfeit heads or the old style small wicking hole nautilus replacement heads.
I added the watt range it is not printed on the head, because you seem confused with the V/W thing.

Or maybe you are using a power device that has poor power regulation / inaccurate output regulation or doesn’t down regulate output at all.
7 watts is not well above 3v.
3.34v / 1.6Ω = 7w
3.54v / 1.8Ω = 7w

 

[Gramdogg]

yikes its 6.66w sorry I ment to say the 10w other guy uses as thats who I was repling to not OP. It is nautilus coils... not hard to rebuild and people use there coils for months with PGA cleanings. Put it in a closed bottle and shake it every few hours. The gunk will break down, shake, repeat... they come out looking like a brand new coil. Water once a week, PGA once a month and they should last for months. You don't dry burn cotton so you have to blow excess out by plugging one end.

 

[Gramdogg]

3.54v is well above 3v IMO but yeah it's just old stock where 4.2v is the max recommended on them. See where confusion came from now . Don't know if new ones are built better but old ones usually read 2-2.2Ohm so they could be ran higher volts then suggested without any problems. Depends if OP has old or new stock I guess more then anything.

 

[Gramdogg]

Sorry again for the confusion I haven't got new coil heads in ages. After 3 packs at $20 each of the old ones that lasted 7-10days I said I gotta learn to rebuild these things lol. I started cleaning first but got into just rebuilding everything later. Never used PGA so I can only confirm vodka.

 

[Topwater Elvis]

The old style small wicking hole authentic aspire nautilus bvc heads were marked 3.3v ~ 5v on the 1.6Ω & 3.3v - 6v on the 1.8Ω.
They both worked extremely well at higher power levels if you used a liquid thin enough to wick well.
The wicking material was a controversial and concerning to many bioceramic fiber / cloth and were discontinued early to mid 2015 due to public pressure surrounding the safety of the mystery wicking material. They do / did not contain any cotton wicking material only the bioceramic fiber/cloth.
If your small wicking hole BVC heads are marked with any other voltage range they are counterfeit. no telling what type of wicking material is used inside them.

Authentic newer style large wicking hole cotton wicking material nautilus heads are all marked the same as I posted before. All nautilus BVC heads also have BVC marked on the side of the head,

I think you’re confusing nautilus BDC (bottom dual coil) heads with nautilus BVC (bottom vertical coil).
BDC’s were poor performers had small wicking holes and do not work well at high power levels They are much easier to rebuild successfully.
Authentic nautilus BDC heads were marked 3v - 4.2v 1.6Ω and 3v - 5v 1.8Ω

There is a night & day difference in all around vape quality & power handling between the BDC and BVC, the BVC heads are far better.

 

[Gramdogg]

I just go by what Aspire support told me, 8-11w and life depends on PG/VG and how much you vape. 8-11w is 3.6-4.8v

 

[Gramdogg]

I have been vaping for 2 summers now, and have totally stopped smoking cigs. So thankful for E-Cigs.
Heres my dilemna. I use an MVP 20 with a Pro-Mini Nautilus tank. I use the BVC 1.8 coils, and have wattage set at 7. I have been using the juice from same retailer for 2 years. My issue is that the local retailer I get coils from, seems as if I get 1 coil from pack to last me 7-10 days. All others from same pack 3-4 days before they start changing. This is getting costly, 5 coils in pack for 22.00. I need to know who to get coils from to last me 7-10 days from EACH coil within the pack.
Thanks

We need more info, If you use high VG go with what me and Aspire support recommends. If you use high PG go by what the coil says or 4.8-7.5v he recommends. Some like hot vape and some like cool vape, find your sweet spot and ignore peoples/company recommendations. Start at 3v and keep going up till it taste off to you then lower it about .4v. Assuming if you been vaping 2 yrs you already know 7w is your sweet spot and you use high VG like me.

 

[Topwater Elvis]

Actually 8w - 11w = using the 1.8Ω head 3.79v ~ 4.44v - using the 1.6Ω head 3.57v ~ 4.19v.
The high of 4.8v you mention is;
4.8v/ 1.8Ω = 12.8w
4.8v/1.6Ω = 14.4w
You seem very confused on this whole V/W ohms law thing.

Your silly assertion that anyone said anything about using 7.5v (which is 7.5v / 1.8Ω = 31.25 watts) with an authentic aspire nautilus BVC head further demonstrates your utter confusion about what is being said & talked about in this thread.

In one of your previous posts you said your heads are marked 3v - 4.2v on the 1.6Ω and 3 - 5v on the 1.8Ω
The only authentic aspire nautilus heads marked this way were/are the BDC heads, this thread is about the BVC heads.
There is a night and day difference, one is not in anyway comparable to the other.
If by some very slim chance yours are BVC heads and marked the way you say they are, they are counterfeit.
Your experience with counterfeit BVC heads or even authentic BDC heads would have no bearing or useful information pertaining to authentic aspire nautilus BVC heads.

Almost everything you’ve posted in this thread is completely inaccurate & irrelevant, this thread isn’t about you, your rebuildables or nautilus BDC heads.

The only explanations for your experiences with nautilus BVC heads is you are confusing BVC (bottom vertical coil) with BDC (bottom dual coil), or, using counterfeit heads , or, you are using a power device that either inaccurately or does not down regulate output.

If you actually contact aspire support about power ranges for use with the authentic large wicking hole newer style nautilus BVC heads they will tell you the optimum range is what is printed on the head, but, you can use them at a power level that suits your individual preference.
4.2v - 5v for the 1.8Ω which is 9.8w - 13.8w
3.3v - 4.2v for the 1.6Ω which is 6.8w - 11w

If your nautilus heads are marked with any other voltage range they are either BDC heads, old style small wicking hole BVC heads or counterfeit.

Nothing Ive said in this thread pertains to the nautilus heads made with different wire types & coil configurations manufactured by a few companies (not aspire).

 

[Gramdogg]

Sorry thought you said they say 6v and many use well above recommended. Since you didn't think 3.54v was well above 3v isn't well above I assumed you ment closer to 7.5v. I said mine I'd say 3v-5v but can't go over 4.2v myself with high VG. You use 50/50 unsweetened so almost everything you’ve posted in this thread is completely inaccurate & irrelevant, this thread isn’t about you. Support is not always good support 8w-11w is what Aspire told me even though I asked for volts. 3.8 to 4.4 or lower or higher is fine depends on your juice, 4 people here use less then recommended 2 use more then recommended.

 

[ShamrockPat]

@Topwater Elvis Amen brother. Some posters, eh. Reminds me of a great saying. "It is better to be thought a fool, than to speak and remove all doubt." Buth that's OK. The 'ignore user' feature works wonders.

Almost everything you’ve posted in this thread is completely inaccurate & irrelevant, this thread isn’t about you, your rebuildables or nautilus BDC heads.

 

[Topwater Elvis]

You seem to have a reading comprehension problem so I’ll list the voltage ranges for the various authentic nautilus heads one last time.

BDC heads only are marked = 1.6Ω 3v - 4.2v / 1.8Ω 3v - 5v.
Old style small wicking hole authentic nautilus BVC heads are marked - 1.6Ω 3.3v - 5v / 1.8Ω 3.3v - 6v.
Newer style authentic nautilus BVC heads are marked - 1.6Ω 3.3v - 4.2v / 1.8Ω 4.2v - 5v.

The reason yours are marked 3v - 5v is because they are BDC, not BVC replacement heads, or are an off brand counterfeit BVC.

This thread is not about BDC heads but obviously is what Gramdogg keeps talking about because the only authentic nautilus head with this voltage range marked on the side of the head are the BDC heads.
From the very beginning this thread was about BVC replacement atomizer heads not BDC. The two are very different.

If you don’t know or understand the difference between nautilus BDC and the BVC heads or are relaying your experience with counterfeit bvc heads all your input does is confuse new folks looking for help.

Example of more reading comprehension failure, I never mentioned or said unsweetened. VG is fairly sweet all by itself.
I use non sweet meaning no added sweeteners, the flavorings and VG have all the sweetness I care for. They actually are sweet tasting, not smack you in the face syrupy sweet.

My wife vapes 40 pg / 60 vg clear non sweet liquid at 12.2w ~ 12.8w all day every day using a 1.8Ω BVC head and gets at least the same usually better head life than I do.

 

[Gramdogg]

"I use clear non sweet 50/50", "You've obviously never run clear, unsweetened juice.", "The old style small wicking hole authentic aspire nautilus bvc heads were marked 3.3v ~ 5v on the 1.6Ω & 3.3v - 6v on the 1.8Ω." Told you mine are old style, OP never mentioned, so 7.5v is just "well above" for old style. 6.5v for new? Just assuming thats what you ment. 5.54v isn't well above based on your comments so what is? Seem to have a reading comprehension problem on both ends. Sorry. Mine as many do are reading above 1.8 Ohm so 8w-11w is 3.8-4.4v. Didn't say they were marked at all. Now it's reading 1.87 and says 3.87-4.54... what was recommended by Aspire support on Facebook. If you chain vape sweet high VG 7-10 days at lower watts is normal, higher and it won't wick fast enough and get dry hits. At least wait for the OP to tell us what ratio they use before you call me clueless lol. I wouldn't call 40/60 high VG either. My old evods could run 40/60 though 50/50 was recommended.

 

[Topwater Elvis]

You're simply not understanding you are not using authentic aspire nautilus BVC replacement atomizer heads if they are not clearly marked.
All authentic aspire nautilus BVC heads have BVC and the resistance & voltage range marked/printed/etched on the body of the head.

IF yours are not marked with the Ω & voltage range they are not authentic aspire nautilus product.
Anything you interject about counterfeit heads has absolutely no meaningful relation to or useful accurate information for someone using authentic heads.
Anything about BDC heads you interject into a conversation about BVC heads also has no meaningful relation to or useful accurate information for someone using BVC heads.
The two are completely different internally.

Here you gave the impression yours are marked.

Mine/yours must be old or you/I have clones mine I'd say 1.6Ohm 3-4.2v 1.8Ohm 3-5v. No mention of watts on them but 7w would be well above 3v. I have never hit the high end of a recommended watt/volt before myself... usually low/middle is my sweet spot. 3.4v or 6-6.5w on 1.8ohm for me, above 4v and it gets nasty to me.

Like Ive said the only authentic aspire nautilus head that is marked with the voltage range you mention are the BDC.
Again, the two ( BDC vs BVC) are not at all comparable.

The older style small wicking hole BVC heads are marked BVC 1.6Ω 3.3v - 5v and 1.8Ω 3.3v - 6v.

I clearly stated what power range I normally use them in, minimum 10.8w to 16.2w. That is my normal range / ADV range, there are times I exceed that for a few hits.

 

[Gramdogg]

Yeah, no. Sorry for the confusing bad wording, I seen another post about "DVC" did they start making them duel BVC as well? That would make a HUGE difference too.
