Perfect usage of MNKE 26650 IMR 3500 mAh?

[treehead]

Hey everybody, I've really been diggin' 26650 everything lately; mods, rda's, higher amps, longer battery life etc. So I decided to try a different battery other than the Sony 60amp VT's. So as the title suggests, I ended up going with these 3500mAh MNKE IMR's.

From what I understand these guys are champs at battery life, they may not allow you to sub-sub-ohm, which I (safely) like to do honestly, but they have a 60amp burst limit, which is perfectly adequate to me.

So I was wondering if anyone's figured out the best application of these camel's, should I keep them around .2ohms and higher? Have you found they run out much quicker with lower ohms, negating the battery life? What I want to do is to basically build them fairly close the their burst amp limit, and see what the new battery life is like. I have a feeling I'll be pretty happy.

vape on! I have two battery's now! Yay! No more waiting half a day for my Sony to recharge!

Silly post now that I've used it I realize. It does last quite a bit longer, it just doesn't have that "punch" the Sony does. Honestly I like both equally in their own way, I think I'll be putting them both to good use for their own applications.

Sony VT: Super low ohm (0.08, possibly lower...safely), smaller quick hitting coils. I'm think these are better for my style, so I'm going to want two of these bad boys around for most of my builds.

MNKE: Low ohm to "normal" ohm lol 0.1+, for bigger, longer ramp up time coils, that I want to chill out and slow vape with all day.

Both are excellent, even near the limits (while always staying in safe range), neither of these show any sign whatsoever of even getting lukewarm. The metal on my mod's stay ice cold like my room temp.

I didn't think of those MNKE as suitable for going that high in amp draw treehead, but that was from reviews I've read, I don't have any myself.

So how do you know you're staying in the safe zone of the cell when going under 0.08 ohms with the VTs?

Specs on those batteries seem to vary depending on where / who you get the specs from.
I'm not saying anything 'for' or 'against' these batteries just wondering why the specs are reported differently.

Sorry I don't want to raise any eyebrows here , but believe me I do my math (and going "under" 0.08 ohms, isn't go much lower at all lol).

The Sony 26650 VT's have a concrete continuous Amp discharge rate of 60amps. So applying that to a 0.08 circuit at the (worst case scenario) full charge of 3.7volts, that'll put me at 46.25amps, which is no more dangerous than running a powerful flashlight. So given that these have a continuous rate of 50amps, and they are 2600mAh LiIon batteries, you can calculate that they are actually rated for a 5 second burst of 120 amps! (Of course I (nor ANYBODY), should ever go near that burst limit on these 26650's) But no human needs that many watts in their vape so, I'm well within the safe zone.

The LiIon 3500mAh MNKE's have a continuous discharge rate of 20Amps, and an (8 second, which is too long for me!) burst rate of 60amps, so if I use them at their max charge of 4.2 for 0.1ohms+, I'll only be taxing them at 42amps, which some may find scary, but I'm very aware of the battery chemistry, and what to look out for (heat, wavering current etc., these puppies haven't so much as gotten luke-warm on me yet, even under heavy chain vaping), and I haven't had any warning signs whatsoever. Plus even if I didn't know anything about battery chem., the 60amp discharge rate is what all vendors unanimously decide is safe for consumers to use, so even if there is a factor I'm unaware of, there's apparently been some empirical study on these by real engineers to determine the safe burst discharge rate. (Plus I'm using 18 less amps than it's capable of (for 5 second bursts), no explosions here .)

Sony SE 26650 VT's: 50amp continuous, theoretical 5 second burst discharge rate of 120amps (which I'll never come close to using, neither should anyone else) I'm using 46.25amps.

MNKE 26650'S: 20amp continuous, confirmed 5 second burst discharge rate of 60amps. I'm using 42amps.


Thanks for your concern brother, I like ECF because we have people watching our backs in case we do something silly. God knows we don't need to give the FDA an actual good reason right now.

Interesting, thanks for the research man.

10 seconds pulse? That's a kinda scary claim, talk about being lenient lol, who on earth needs to burst their 60 amp coils for 10 seconds anyway?!

The manufacturers site indeed says "instantaneous burst for 60 amps", which I would imagine doesn't mean 10 seconds . However a local vendor in town whom I really trust, does have actual battery graphing equipment, and when I bought these we jested about the ratings etc., and he found the 62 amp burst test to be safe for 5 seconds (which again, nobody should ever do anyway), granted that was only a 5 time firing test he did, probably not wise to do constantly, unless you want a hot battery, or degraded battery life at minimum.

I think it's ESSENTIAL TO SAFETY for anyone to stay a decent amount away from the burst amp limit anyway, I stay below at least 75% of it's max burst limit, which is what I posted just now (42 amps), and that's frankly an intense build for me (or anybody I can guarantee), my ADV's are almost always around 30amps anyway, I'm not constantly pushing my batteries to their limits, this was basically a "find out these battery's sweet spots" post.


Thanks again for the input Elvis , that's definitely a very uncertain situation regarding those vendors claims, my guess is they are bumping up the burst times for sales...

ATTENTION!

THE CONTINUOUS DISCHARGE RATE FOR SONY SE 26650 VT'S IS ACTUALLY 50AMPS!

Apparently my big gorilla fingers hit the "6" instead of "5" in the above original post. I just want to clear that up in case anybody get's the wrong idea, granted the Sony's are most likely more than capable of 60amps (pulse), however the continuous is actually 50, and don't want anyone trying because of my silly typo.

(Thanks Elvis, and Ryedan for bringing me back to the post, otherwise I would've missed that )

For whatever reason, I'm unable to edit the original post, so I thought I'd make the correction here.

for real bruh we all want the elusive sony. Can someone just call them and ask if they still make it.

Thinking I should order a box of them from sony.....

I'm really sorry to say the ENTIRE INTERNET is empty , it's amazing, I've never seen a product missing from the internet lol. The only two I've found after a quick search just now are

Here: (shhhhhhh, there's only 9 left...well 7 because I just bought two, now I have a family of four .)
Sony SE US26650VT IMR 2600mAh 50A Ultra High Drain Battery (Kuala Lumpur, end time 6/26/2015 12:15:00 AM MYT)

(I was lucky enough to live in Alaska, where there are maybe a handful of vendors, and I (thank GOD) bought two of them before Sony temporarily stopped making them, which was smart, because now when they make more, vapers will flock to vendors and buy 20 at a time lol. This website is a malaysian website though, with quite steep shipping just letting you know, the picture is absolutely identical to my sony's, and so is the specifications, so I don't think there's anything to be worried about!)

and Here: (which is a 10 battery bulk buy, I'm thinking of starting a thread about a group buy soon to get some people together to buy them. )
SE US26650VT 20C 50Amps 26650 rechargeable 3.7V original for SONY battery, View 26650 original for SONY battery, HHS Product Details from Shenzhen Honghaosheng Electronics Co., Ltd. on Alibaba.com

There's also a vendor or two on eBay Canada in which I've messaged to find out if they'll sell two to me before the malaysian ones ship, hopefully I'll hear back tonight!

Good luck brother, it's a hunt out there.

Ha, for true. I've always been able to find '1' of something, well, except for maybe the DNA30 boards and those freaking Fat Daddy connectors - one for which I got in on a co-op here, and the other I just stayed up until 4am the day he was restocking and quickly purchased a couple. Ah, the things we do for mod.

Looks like the only harder than finding that high-end battery, is finding a fit holder for it. I am currently going to mod a D cell holder.

Thanks folks!
