I have a few questions about my mods/batteries...

[Noahfence]

Hey all,

It's a bit of a long post... Maybe a good read for some?

I have been browsing for quite some time I decided to actually register so I can get involved in conversations instead of reading and not finding answers I may need.

I have a mvp 2.0 and I love it. Love the long battery life and the ability to use VW/VV.
I currently have a number of different tanks including kanger mini protank 3, iclear 16B/30B and my favourite the aerotank v2.

I also have a panzer clone with a plume veil RDA and I use 18650 2100mAh batteries.
I have this at 0.25 ohms.

Along side this there are some smaller stick batteries (standard ones you get with starter kits etc) which I use when the mvp isn't always practical.

My questions are:

When I bought the batteries and the panzer set up from my local store, I was told the batteries were safe to go as low as 0.1 ohms but how can I tell? I see everyone say I should get Sony batteries which are something like 30A? Mine is unbranded and is green with a white sticker on saying 3.7V 2100mAh 18650.

Should I invest in some branded ones?
Dont want to go to 0.1ohm on the panzer and blow my teeth out.

In terms of the mvp, at first 11watts seemed quite a lot but I have seen the dna30 which I have my eye on which will go to 30watts.
If I were to purchase this, I don't want to use it to chase clouds, but could i fit this with a RBA and have abit more than the mvp kicks out flavour/vape wise, but still less than the panzer?
Is the DNA even a good purchase? Is there a better alternative?

Also I have learnt that my mech mod requires me to know when to stop using the battery in it otherwise if i discharge it too much it can be dangerous. Is that correct?
Normally I would tell by the quality of vape but how can one be certain?

For this reason, would a dna30 be a better option as it will tell me when I need to stop using the battery or it will just shut off when it gets too low. Is that correct also?

Thank you for reading, it's my first post so in my head I have a hundred questions but wanted to get these ones out first.

not knowing what the rated continious discharge rate for your batteries and going so low on the restiance on your plume veil, is playing russian roulette. Stop it.. stop it NOW.

Do you understand Ohm's Law? Do you understand how the restitance of your coil and the amp limit of your battery are interconnected? If you dont... stop using that mech mod till you do.

You will not be able to find any real VT5 Sony Battery's, they are all gone... Sony does not plan to make any more. You might be able to find some VTC 4 or 3's which have the same 30A continuious discharge rating. Dont buy them cheap, buy them from a real business... WAY too many fakes on the market these days.

This battery is also recommended by others, as being a true 30A

You should definitely not be using those batteries on a build that low if you don't know A) what brand and model they are, which will tell you B) what their Amp rating is.

With a mech, you do need to know when to stop using the batteries, draining them too low won't usually cause a catastrophic failure, but it can make it so they will no longer hold a charge. If you're going to be using a mech and/or RBA you should have a digital multimeter so you can check the voltage on your batteries and the resistance of your RBA builds, as well as being able to diagnose possible shorts in your mech.

Hi Noah. First of all, read this blog entry about batteries You may find other entries in Bad's blog instructional, too:

Safety first.

If you're thinking about DNA, research the newest DNA entry, the DNA 40 with temperature control, before you decide what you want.

We also have an APV subforum here where you can find all the information you may be interested about advanced APV (batteries and RBAs)and how to use them.

Good luck!

Thank you. I shall be buying some branded batteries which I know the rating of.
I have a cheapy ohm meter so I can check the resistance to make sure it goes no lower than 0.2
I guess you could say I'm starting out in the world of sub ohm.
I have ohms law calculators which im constantly using to get my head round things.
Thanks again for the advice!

Instead of using a mech should I look into a DNA30 device which would be 'safer' than mechs.
Don't get me wrong, I love it, but I use it only around the house and I only want to use it if I know everything is safe

This is a nifty one I use:

Online Conversion - Ohm's Law Calculator

Be safe first. Try higher ohm builds first. You can get plenty of power and vapor without sub-ohming, too.

The battery you described sounds like it might be a Sony VTC4. The white sticker is just something the shop puts on there. I have those stickers on all my LG batteries that say what they are. This is a sony VTC4

Here is a picture of the battery.

good questions.
First off: if you are ever unsure about batteries dont use them.
As for .1 ohm if you dont have a good understanding of ohms law, etc. dont try it ease into it, if you want to sub ohm start at .8 and work down.
As for the DNA30 you can get comparable devices that will perform equally (some better cheaper) but it is a great choice, now as far as less "power" than the panzar that depends on your build and how you set it. I could put a .5 ohm build on my mech mod with a fresh battery (4.1 volts) and it would be putting out around watts and around 8A. If I put the same build on the DNA30 you could bump it up to 30 watts and get close to the same wattage, or you could step it down to say 20 watts if thats more to your liking.

Also with a mechanical mod the voltage applied isn't steady, it starts off at 4.1 if its a freshly charged battery and you can use it down to 3.4ish volts before youd risk over discharging the battery. with a regulated device it keeps the voltage applied constant throughout the use of the battery.

As for being able to tell when the battery is getting low isnt too difficult, performance drops noticeably as the voltage of the battery drops, for me personally performance drops enough for me to change batteries when there is still roughly 3.5 volts left depending on what setup Im using. At first be paranoid lol check the voltage often and eventually youll learn at which point it has dropped too low.

Hope this helps, happy vaping, and feel free to ask any more questions you might have

No other markings other than a smaller qr code marking which I can't read as my phone won't focus that close

 

[loganfl22]

Something I forgot to mention,
with the DNA30 there is no reverse battery protection like on most regulated devices so if you go that route beware which way you put the battery in.

Thank you for all the advice !!

Does the numb top or flat top make a difference other than fit?

 

[Lessifer]

Does the numb top or flat top make a difference other than fit?

That depends on the mod, some are made specifically for button top, some made for flat top, and some can take either.

To the OP, those "look" like Sony vtc4's. Unfortunately there are counterfeit sonys out there so I can't say for certain what you have, and chances are the shop owner couldn't guarantee them being genuine either, unless they purchased from a reputable supplier, and not from wherever they could find the cheapest deal on batteries in bulk.
