Ipv mini/ sub ohm/ battery

[Pikestr28]

So I recently purchased the ipv mini with the Atlantis tank. I then purchased a tugboat V2 clone because I subscribed to zamplebox and want to be able to drip to try out all the new flavors. Plus, I feel like that's the next step in my progression in this hobby that it has become. With that, this is my first sub ohm. So of course, I've been doing a ton of research so I don't blow off my hand or something else. I noticed the 18650 batteries I have aren't capable of sub ohms or high wattage for that matter. I'm pretty sure these batteries will do the trick, but was hoping someone could verify this for me. I won't be building under .5 ohms and won't be using a wattage over 30 watts. I understand these batteries don't get the full 35 amps they claim, only 20. From what I can tell though, I should be well within the safe confines of what my intentions are. Any feedback would be greatly appreciated!

Also, I'm taking all the precautions and bought an ohm reader and all the safety supplies needed for building.

Those batteries are sufficient for what you're doing. The LG HE2 and Samsung 25R are other solid choices. With the resistance/wattage you noted, you're drawing appx 7.75A which gives you plenty of breathing room. Always do the math before firing a new build.

What are you using to calculate exactly what amps are being pulled? I've used the ohm calculator and other devices to try and figure this out. Do you have a specific thing on how you are figuring out how much wattage and resistance is being pulled to figure out which type of battery you need? Hope that questions makes sense.

Plug in all the variables, the APV efficiency for the IPV Mini is 92%, you have the rest.

Thank you very much for this!

I'm thinking you haven't been doing this very long.

No you will not be building below .5ohm and NO you will not be going over 30 watts. The IPV Mini will not allow either.
This is a Regulated mod and is in no way anything like using a Mechanical Mod.

You can use any decent battery in a properly Regulated Mod.
I purchased Samsung 18650 R25's for mine, but my Panasonic CGR18650CH work every bit as well. The Mod does all the boost and control.
The Mod also has several Safety features built in.

I understand the ipv mini won't allow that, and I stated this will be the first time I've done this. I'm just trying to do my homework. I don't want anything blowing up on me. This is merely something that I find fascinating and I love learning about it. In the process of reading about ohms law and doing my research I've began to understand batteries more. This was merely a question to make sure I'm on the right track.

I've been using regulated mods for two years, but have never sub-ohmed.

Also, part of the reason I asked was incase I ever do decide to get into mech mods.

Apples and Oranges.

Pick one subject and stick with it to the final outcome. Avoid getting any information crossed up.

Like I said - Panasonic's work fine in the IPV mini You would NOT want to attempt that on a .2ohm Mechanical Mod.

While the Panasonics will work fine in the IPV Mini, I prefer a cell rated for 20A continuous for more cushion. No such thing as too much when it comes to safety.

Not sure where you are going with that thought. SX130 chip max output is 13.0A and typical input is only 4.5A. Even the Blue Mystery batteries could work, though I advise never using them in an any mod.
But yes, like I said earlier, I purchased (2) 25R's - (Then I kept the second IPV) and I need to pick up (2) more 25R's. Until they arrive, I have all confidence in the Panasonic's. Have been using them in Sub-ohm applications for about a Year now.

My bad, I know I have a bad tendency to jump all over the place. My question was answered in the first post though, and then I just had follow up questions. Anyhow, I guess it seems like everyone is recommending the 25R's now that Sony VTC's are almost impossible to get a hold of.

Not going anywhere with it, just stating my thoughts regarding the cells I use in my mods.

Yes, them or the LG 18650 HE
Both are 20amp continuous 2500Mah

I appreciate the responses and help!

I have 4 of those;
I don't subohm though.

To figure out the amp draw on a regulated mod, use
watts = volts x amps
(actually watts less than volts x amps because of efficiency - assume 80+% efficiency)

Use the low voltage cutoff of the regulated mod; I will assume 3 volts.
Assuming 30 watts
30 = 3 x amps
so amps = 10

Wouldn't this equation almost say that with a 20 amp battery you can't go over 60 watts?

That is correct:
60 = 3 x 20.

If you put on a fresh battery 4 volts, delivering 20amps you can get 80 watts
but on a regulated mod, if you set the mod to 80 watts, once the battery drops below 4 volts, it would have to deliver more than 20 amps to deliver the 80 watts.
When it's down to 3 volts, it would have to deliver 80/3 = 27 amps
