LG INR18650-M26 (10A) cell, overlooked?

[Barkuti]

Datasheet: http://www.datasheetspdf.com/datasheet/download.php?id=1165169
A super-affordable cell aimed at the light electric vehicle market. No serious reviews of it yet. Piqued my interest because of its very affordable pricing and comparatively nice official figures (a Samsung ICR18650-26F/J won't do 10A).

Just curious.

Cheers

A 2500 mAh 10A cell? I guess they're cheap because that was state-of-the-art 5 or more years ago.. Personally, I'd rather pay a bit more for 3000 mAh 20A cells.

However, there's one thing on the spec sheet that's mildly intriguing:

4.5.2 External Short Circuiting Test
Cells are charged per 4.1.1, and the positive and negative terminal is connected by a 100mΩ-wire for 1 hour (Per UL1642).
No explode, No fire

 

[Barkuti]

Rossum, no offence but your quick guess was every bit as cheap as well (LoL!).
Battery manufacturers put a lot of effort in all of their products nowadays, and while I can understand you may prefer to spend a little extra money in a better cell, remember this is aimed at multiple cell pack assembly. So while this cell may not make much sense for your mod given the total price difference, it surely does for a battery pack application where several dozens of extra cells provide extra meat at the same price point.

Cheers

With very good 20A and/or 3000mah cells being available for about 4$, I just don't
see the point in getting the M26.
Aside from the fact, that it's not even on sale at the sites of my *trusted* battery suppliers.

Vapers don't do batterypack assembly. In the worst case they fire little tubebombs right in front of their faces. So imo every sacrifice of safety is just plain stupid.

Absolutely. It probably does make sense for some battery pack assemblies. When your pack might consist of hundreds or even thousands of cells, a dollar or two of savings per cell adds up. But a dollar or two less per cell for a vaper is pretty insignificant.

You do realise this is a vaping forum

100mOhm isn't much of a drain on a battery is it?

 

[mimöschen]

Although it didn't catch fire or exploded right away, doesn't mean that it didn't spew hot venting gas all over the place either.

 

[Barkuti]

mimöschen, the M26 is widely available:

• IMRbatteries - LG M26 18650 2600mAh 10A Battery
• LIION Wholesale - LG M26 18650 10A FLAT TOP 2600MAH BATTERY
• LG M26 18650 2600mah 10A @ liitokala Official Store (#217753) Look at this fellows! Less than $2 a pop to USA shipping included!

Yes sonicbomb, this is a vaping forum, section Batteries and Chargers.

The 100mΩ wire thing is a safety test, it is meant to abuse the cell in a typical way. I once had a short in a battery pack assembly, happened because of a rip in a cell wrap against a sharp copper sheet piece (rookie's mistakes). This kind of short circuit condition isn't as harsh as intentionally doing it with a straight thick piece of wire.

100mOhm isn't much of a drain on a battery is it?

0.1 ohms directly across the battery, continuously, from fully charged to completely dead strikes me as a pretty good torture test for a 10A cell.

Although it didn't catch fire or exploded right away, doesn't mean that it didn't spew hot venting gas all over the place either.

Good point.

 

[mimöschen]

@Barkuti
If someone told me, manure is cheaper than approved cells, I wouldn't stuff that into my mod either.

And no, the M26 is not readily available in Europe. At least not from approved retailers.

But I digress. Imr and Liion have the cell for 4$. Not for under 2$ and I can get compareable batteries with a higher amp rating like the Samsung INR18650-25R or Sanyo UR18650NSX for the same price and the LG HE2 for even less.

This is the Battery and Chargers subforum of a *vaping*site. Noone here cares for batterypacks or flashlights.

 

[Barkuti]

mimöschen, your previous post sounds disrespectful and sort of an untrue generalization.
As I previously said, this forum is dedicated to batteries and chargers. The M26 is a battery in a standard format, so it qualifies. The fact that it does not meet your requirements or it is not easily available to you is of no business here, and don't get me wrong.
My approved retailers are my own wisdom and intuition; what this means is I do not need any external authority to decide for me.
And yes, you know there's people who may be interested in flashlights and battery packs. In fact, the whole industry behind these cells gears to battery pack assemblies: electric tools, laptop packs, vehicles, etc.

Mooch also tests lower drain batteries, not everyone vapes at 500W with a 3S2P pack (neither I do but, who wants some?). I came here to request info for a yet untested cell with a fair price. I do not doubt it will meet its specifications, but some data is always better than no data.
These cells would do good for one of my closest friends, for example; I recommended him a nice powerful regulated mod nearly 4 years ago, together with a pair of the once new HG2 cells. He later told me he mainly vaped at 8W (LoL!)…
Μay all beings be happy.

Cheers fellows

 

[mimöschen]

Honestly I don't care whether you use the M26 or not, nor do I care about from which obscure site you get your cells. But please stop advertising this cell as the best, latest, hottest and most of all cheapest sh*t. It just isn't. Ok, hottest may be true, because LGs are known to run at higher temperatures than compareable cells from other manufacturers with the same CDR.
The 10amp cdr is set for a reason, no matter if it explodes right away at an 40 amp discharge or not. And by the way other IMR or INR cells behave the same. So that's absolutely no proof, that this cell is safer than any other.
But even if you're vaping at lower wattages, there are better cells for the same price available.

 

[Topwater Elvis]

Jeez people,
Barkuti never mentioned best, newest, hottest, good for vaping, safer or advertised the cell.

He said the cell " Piqued my interest because of its very affordable pricing and comparatively nice official figures "

While a 10a 2500mah cell doesn't sound like much to talk about to some folks, there are others that would be thrilled to find this option. Many vapers never exceed 2a - 8a or 24w per cell.

There are several places in the world batteries aren't readily available and or some to all the typical name brands & models we usually use are difficult to impossible to find. And some that laws severely limit & control importation and restrict the sale of such things. Some where the cells may cost $3 usd but shipping costs & import duty can be as much as $12 usd per cell.

These same folks just might be able to find this cell from a non vaping type source readily available.

If a 2500mah 10a cell doesn't interest you, why interject negitivity or put words in the OP's mouth trying to discredit his intentions.

 

[mimöschen]

But he mentioned, that the cell doesn't catch fire or explode when shorted.
This is not a sign of quality. This is to be expected from any IMR/INR cell. At least if we're talking about cells from the big 4.

Concerning availability in other countries, I've seen better cells for the same price on Ali. But what matters is the question, whether they sell authentics or rip-offs.
And Ali, like eBay and Amazon, is known to be flooded with fake cells.
So comparing that site and their prices with that of trusted retailers is at least questionable. And comparing prices of that cell on various well reputed sites, doesn't even underline that the M26 is that much cheaper.

 

[Topwater Elvis]

He mentioned a normal / routine test performed by the manufacturer included in the spec sheet only after it was brought up by another member.
Same or very similar test all decent manufacturers use.

This cell is manufactured by LG Chem, one of the ' big 4' as you call them, even though there is only 3 left after the Panasonic / Sanyo merger (2009) & Murata taking over Sony's battery division (SED).

He linked to 2 trusted reputable US based cell sources.
To me $2.99 is inexpensive for an LG cell, it may not have the spec's I need or want but is there any harm in member passing along something he found interesting.

All the cells we use are intended for multiple cell pack assembly, not one is approved or recommended by the manufacturer for end consumer use / retail.

Seems you just want to argue, Im not that guy.

 

[Barkuti]

Only three Topwater Elvis? Samsung, LG, Panasonic/Sanyo and Murata/Sony, I count 4… did I missed something?

Cheers

 

[Topwater Elvis]

No you didn't miss anything, dang it, I did, sometimes there is a disconnect between my brain & fingers.

No excuse, My apologies to all.

 

[Rossum]

To me $2.99 is inexpensive for an LG cell, it may not have the spec's I need or want but is there any harm in member passing along something he found interesting.

No, there's no harm in it. But I still contend that these cells don't have much appeal to the vaping community, which is probably why they've been "overlooked" here.
