Dry Hits On My Parallel 18650 But Not 18650 Tube Mod

An online vape shop here at Greece at the description for dotBox Dual Mech mod says"

"Switch to Parallel Mode for longer Vaping time and exceptional power from two 18650 batteries".

The dotbox dual mech has the option to select series or parallel connection via a switch.
I send them a email that this doesn't apply (for the same power output always),for example 0.1 ohm coil in parallel connection and 0.4 ohm coil in series connection.

Two batteries in series provide the same amount of watt hours a parallel connection does.

The vapeshop replied and told me that the description is copy and paste from Dotmod.com

Indeed.
QUOTE from dotBox Dual Mech - dotmodretail
"Last Longer. Switch to Parallel Mode for longer Vaping time and exceptional power from two 18650 batteries".

The vape shop also said that the voltage sag at parallel connection is spread out over the two batteries in Parallel.Thus more vaping time than using a series connection.

Okey I made the calculations for voltage sag using for example two Sony VTC5A 18650 batteries with a DC Internal Resistance = 18.6mOhms (0.018 ohm).

I got the same voltage sag 0.378 V in both configurations (0.1 build in parallel-0.4 build in series).

Am i correct or am I missing something?(i'll send to the vape shop the link for this thread so they can read your opinions because i think they believe i'm talking bulls..t!  

Any recommendations for upgrading? I have a awesome custom 18650 parallel box, infinite stingray and atomo. My friend has a paragon midnight v2 and flawless tug combo. Any of them a keeper? I'm wanting to get a harder hitting device and don't mind going authentic. Any advice would be greatly appreciated?  

Hello All,

Does anyone know which 18650 battery would last the longest when vaping at 13 watts? I have listed some below but any not listed recommendations are welcome as well.
(PS please don't respond with battery safety information or suggestions for me to look at mooch ratings)
Also, does anyone know if the vendors in the last 3 below links are reliable?

Thanks!

So i was thinking of starting a thread which might list every mod past and present which would be compiled by you from one day to the next. At first i thought it wouldn't be practical because no one would know if a mod had been added unless they read through the entire thread.

Then i thought if a list from A though Z were compiled systematically by members by copying and pasting the most recent list in this thread, and then contributing to it, ensuring your entries are inserted alphabetically (Even if it's only one or two mods), then eventually this thread could contain pretty much every mod that exists, and would be updated regularly, by you !. No pictures please !. Only brief descriptions such as "company name / name of mod / type of mod".

What better place for such a list than ECF, "The world's largest e-cigarette website.

Here's my contribution to start it off :

________________________________________


it's a list of all the mods i own at this present time.

If you're going to add to the list then you can add any mods you can think off as long as you place those mods into the existing alphabetical order ( description should start with the company name). Batteries such as, say, vision twist aren't mods so lets not get into those. Tube mods and box mods (Includes internal/built in battery mods) only please (Squonkers included)

And lets not forget Mechanicals.

If you think a previous desciption is incorrect then correct it.

Ensuring company names come first in your description will enable a logical, consistant "alphabetical" understanding of the list by anyone who views it.

If you don't know the name of the company who made the mod just insert the name of the mod etc.  

So I just bought a kit, it doesn't come with batteries -- which I wasn't told (was led to believe it was charged through the USB port according to vape store employee). So I ordered x4 Nitecore-NL1834 18650 3400mAh 3.7 Protected Lithium Ion (Li-ion) batteries and now the door won't close. I read an old article saying that Protected 18650 can be bigger. If there's a possibility of buying batteries that cost $18 a pop shouldn't they let you know there's a chance that it won't be the right size?
Is there a trick to getting the battery lid to close or do I need to now buy unprotected 18650 batteries and hopefully get my money back on the protected batteries I bought?  

Hey Guys,

I have been wanting to use a mech mod for quite some time now. But I didn’t want to rush into things, given that they can be dangerous if not used properly.

To prepare I have studied ohm’s law and have a pretty decent grasp on it. And have a calculator app on my phone.

I have checked out Mooch’s battery recommendations and have a good idea of what batteries to use and which to avoid.

I still do have a few questions I was hoping an experienced Mech user could help me answer:

- What would be the “sweet spot” as far as resistance and safety go for a dual coil set up? Obviously I want to go as low as possible and have a hard hitting vape. But I also want to be safe. I plan to use a dual 18650 Parallel mod (The Clutch X18). I would be most likely be using Sony Murata batteries as I cant find any Samsungs where i live. I’m thinking somewhere around 0.17-0.2? Or would it be safe to go lower than that? I will of course test my build on an ohm reader and regulated mod before throwing it on the mech to be safe.

- Are there any other general safety tips? Ive heard that you want to screw the Atty down all the way first, before inserting the batteries. And then insert the batteries. And when removing the batteries i heard you want to slightly unscrew the atty first, and then carefully remove the batteries? Can anyone please confirm if this is correct.

- Is its safe to chain vape on a dual 18650 parallel mod? When I say chain vape I mean like maybe taking 5-6 big hits back to back. Then waiting 3-5 minutes, dripping some juice and then doing another 5-6 hits.

- Is there anything I should be monitoring while I’m vaping? Like the heat of the batteries? From what I’ve read, the batteries drain quite fast on a mech. And after some experience you will just kind of know when they need charging because the vape experience changes. Is there anything I’m missing? Or something i should be looking out for?

- I can only vape in my kitchen. And sometimes there might be a little bit of water on the counter from someone’s drink sweating, or drops after someone washed their hands etc. Is this a risk? I will of course do my best to keep all surfaces dry. I’m not talking about large amounts of water or submerging or getting the mod really wet. But just what one might find on a kitchen counter.

- Any other tips you could throw my way would be great!

Thanks in advance!  

I have several mods, but the kicked 69 with an Aerotank has always been a favorite.

I have used it with a Chi You extension, but was wondering if someone has found an alternative that allows the mod to telescope with a kick+18650 installed - like a tube section that fits directly below the button section, etc.

The Chi You section is kinda awkward, so I have to use it with 18500 batteries and live with their shorter battery life.  

I just bought 2 18650 Batteries today. I realized that on one of them, there is a small scratch. Is it still safe to use?  

Just bought a brand new pair IMR 18650 2500mah batteries, when they start getting low and you're getting late fee from batteries did you take them out and charge them or let them drain completely, the mod shows a little juice left in them but I'm getting a very light vape.  

I am interested in getting the VooPoo Drag X 18650 , but prefer RTA's. The tank that comes with it is a magnetic PNP tank. Does anyone know if there is a good replacement RTA tank that works with this magnetic pnp system? Preferably 4ml +...Thanks
