Bateries for Vandy Vape Pulse X

[Lucky Patrick]

I see it works with 3 different types of bateries: 18650, 20700 and 21700

Why?

Whats the difference here?

I know i need to learn more about these things to know if/how they perform differently. So any help to direct me where i could learn more about the topic would be great.

Thanks

Why? Allowing the consumer a choice can be beneficial

Difference? The larger 21700 battery can utilize higher capacity (mAh) for a similar or even higher CDR (Constant Discharge Rate)

What is better? Subjective – would depend on what suits the individual the most. Someone running high wattage would want to look into a high CDR battery so that they are not over stressing the cell. Someone running low wattage may want a high capacity battery to prolong run time. 18650 cells are a very popular size with much to choose from. 20700 and 21700 are not as common, although starting to gain in popularity, so selection is smaller than their smaller 18650 counterparts.

Perfect!

Damn you guys are the best. I was expecting to get roasted for this noob question

 

[Punk In Drublic]

Was a legit question.

Many if not all devices that allow 2x700 cells can usually accept an 18650 with an adaptor. This allows a consumer to utilize a more common sized cell that they may already own. Some devices even allow a much wider range of sized cells – the Geekvape Aegis 100 can accept 18650, 26650, 20700 and 21700 (the later 2 requires a different battery cap that can be purchased separately or is included in some kits)

 

[Baditude]

I agree with Punk above.

18650 size cells are the more common and popular size. The larger size cells have more electrolye inside so they often have a higher amp rating or a higher capacity rating, but downside is larger cells often require a larger/heavier battery device.

Know your battery specification terms:

Capacity (mAh) gives an indication of how long a battery will last per charge during use.

Amp rating (continuous discharge rating) indicates, in layman terms, the power output of the cell. We generally choose the battery we use by the cells amp rating depending upon the wattage setting we plan to use.

Those 20x battery slots usually require some sort of adapter or sleeve to fit an 18650. Should come with the mod. Good thing to not lose, as you may hit a period with no charged 20x batteries around but a bunch of charged
18650s. So handy to have around. I think the 21700 is becoming the standard over 20700 these days based on availability. Here's a recent but our if date by a week list of Mooch's recommended batteries. And he is out battery guru who we all pay attention to as he extensively tests these batteries to assure they perform as expected. There's a list of trusted vendors on the bottom. eBay and Amazon are both to be avoided due to counterfeits and misrated rewraps sold.

My preference is the 40T for the best balance of power and capacity. If I were vaping high wattage (over 50-60W) I'd use the 30T. Both from Samsung. For 18650s the 20S offers 30A and 2,000 mAh and the Sony VTC5A 25A and 2500 mAh. As a midrange vaper the 40T and the 25R from Samsung are my standard stock, along with some VTC5A for 25A in my mech squonks.

In addition -

18650 - 18mm wide 65mm in length
20700 - 20mm wide 70mm in length
21700 - 21mm wide 70 mm in length

A larger battery using the right chemistry can have a higher capacity (mAh) and a higher amp limit (CDR) than a smaller one.
So good 20700 and 21700 batteries offer vapers more capacity at the cost of a larger cell.

In case that leaves you wondering what the final 0 is for, it was originally an O (letter, not number) and it refers to the shape of the battery: round, or, more accurately, cylindrical.

Damn! Amazing, you guys killed it.

So for someone who likes to vape in the 40 to 60 range i should not be using something like the samsung 18650 30Q, right?

Instead I should be going for something like the samsung 18650 - 25R?

What would happen if i vaped at 60w with the 30Q? I imagine that would be unsafe?

 

[Lucky Patrick]

What about the "Efest IMR 21700 4000mAh 30A" for a 21700 option?

Would that be ok?

Given the number of good brand name 21700s I'd avoid a rewrap like Efest. About the only one that seems reliable in that rewrap crowd seems to be Golisi. Also the Efest you're referring to is a 20700 not a 21700 (if you got it off Mooch's chart). For your wattage range the 40T is nice, 25A so good there and 4000 mAh capacity. I've been very happy with them.

You seem to understand the concept.

Well, you'd be pushing that battery to perform a task it was not designed to do. That is known as misuse or abuse of the battery. Actually "pushing" is a misnomer phrase that we all use incorrectly, as batteries don't push current but the current is "drawn" from the battery.

In your example, all the electrical current will be drawn from the battery. It doesn't have the current demanded of it, but it gives all that it can give. The battery drains faster than it should (over discharge), which produces heat. Heat is the enemy of batteries. If the internal temperature of the battery is excessive, it can result in "battery venting" (bad) or even "thermal runaway" (real bad). Read their definitions below:

[stols001]

I am just going to say that when it comes to battery adaptors, some are better than others, and may eventually die if you have to keep removing them.

If I can put the largest size battery in a mod, I am going to mainly because I see it as easier, I can get better run time with the largest size (usually) but mainly because I don't mind a bit of heft, and I don't at ALL mind a bit more run time (keep in mind, I vape puny wattages) but I really see no reason not to use the BIGGEST (unless a smaller battery would be more practical but to be honest I am not the biggest fan of battery sleeves.

I think someone was musing about whether they could charge their battery with the sleeve still ON and I think it might have been the Vandy Vape x I can't remember... I think the consensus was YES, provided you kept an eye on it (sleeve could case more overheating potentially, etc.

I've never been a fan of the Efest brand. They have a LONG and notorious history of exaggerating the amp ratings and capacity ratings of their batteries, which is false advertising but since they are made in China they get away with it. On principle alone I'll never buy an Efest battery.

For your device and wattage range, like others have already said, I would suggest the Samsung 40T. Great battery for your situation. Here is a link to a reputable dealer in the US (not sure what continent your located in, so I'm just going with what I know and use).

I mentioned that efest 21700 one because i have an order ready to be placed at an online store and this is what they have.

Keep in mind i dont live in the US, so i dont have easy access to a .... ton of brands and options. I might be able to find in other stores, i dont know, but then its another shipping fee and the mail service here isnt cheap, so it would be beneficial if i could just order everything from one place. Otherwise id be paying more than 50% of the battery price just for the shipping of a single battery lol
Of course its better to pay a little extra and not having the thing blow up in my hands and becoming jamie f-ing lanister, lol, so what do you think?

I literally copy pasted the item name from the store into my post, so im not sure what you mean by being a 20700 and not a 21700. Are you saying they are advertising the product incorrectly? Here is the link: Bateria IMR 21700 4000mAh 30A - Efest

They have the 25A though, so i guess its fine if i go for this, even if its not the absolute best option, right?

Chances are likely that is a Samsung 40T rewrap (not 30A like they claim, but 25A), but with rewrapers you take a chance of it not being that cell under the wrap.

Sometimes they tend to put a good battery out for a while, then put another cell in the wrap (typically worse, like first put out a good true 25A battery then swap the cell under the wrap with a 15A battery after a while and not change the wrap to indicate the lower amp rating). The good thing is that there are a lot less 21700 batteries for them to choose from, and it is more likely to be the cell they claim, but it's never a guarantee with rewraps.

 

[Eskie]

Sorry, didn't see a link on the first post and didn't know your location. I have zero idea what's under that wrap. As @Zaryk pointed out it is likely a 40T, which if it is will be a fine battery. It's that uncertainty we all try to avoid. My only advice is don't try to draw the max on it, and check it once in a while to see if it gets warm with normal use. If it's getting toasty I'd stop using it.

Sorry, best advice I can offer.
