Is this latest recommendation literally supposed to be 50mm in length up the mod, or circumference, or circle area?
BTW, does anyone know yet whether the latest AW 18650 "imr" is the same as the panasonic nickel limn?
Thanks Asdaq! Mailman stalking begins!
I do not Mailman stalk anymore - I setup an alert signal on the door - it alerts me when the mailbox is touched... Saved a lot of trips out to the road.
Well, I have thought about setting it up anyways...
Well, there you go then. However, I don't really understand why there's a disclaimer that says 4000mAh. A 26650 has almost exactly double the volume of an 18650 so the charge capacity should be double. It should be at least 5000mAh on the bench.
I saw that video before. Very interesting. I was surprised that neither cell caught on fire. They are safer than I thought. You can see the lower internal resistance of the AW IMR in the temperature readings. Also, the fact the AW cell caused the insulation on the wires to smoke and the Panasonic cell did not.
You think that the PTC might have something to do with that?
Or do the IMR cells even have a PTC?

Just like everything else in the world bigger is going to be better - right? Bigger bang also... Why don't ya'll wait for the 52105 series and get 10,000mah - it will probably be out in a few months... You can take out one side of the house with this one...
Good point actually, I didn't think about that before. If you look at the CGR18650CH data sheet, item #2 in the cross-section is the PTC device. That would account for the higher cell resistance (PTC devices have some resistance even when cold) and why the cell didn't get nearly as hot as the AW cell on the short test. The PTC probably kicked-in and dropped current quite a bit. I don't know if the AW cell has one or not, but I would guess it doesn't by how hot the wires got in the video. It takes quite a bit of current to get wires that thick that hot.
or a pair of 38120 LiFePO4 3.2 volt cell in series for 6.4 volts loaded with about ANY atty made
10,000mah. and a pretty good C rating.
I will not. You said that never met such a batteries, so I tried to help
If you read forums about 18650 Trustfire batteries, you will see, that mostly real capacity of them sufficiently lower than declared. For 26650 from trustfire 4000 ma-h should be OK, honest statement. Particularly for big currents.

Slimest,
"Well, there you go then" is an "acknowledgment".
Craig is not telling you to leave.
At least I don't think so
If anyone gets one of these 26650 protected cells, I would be interested in seeing the protection board. I use the "2 mosfet" DX boards. But haven't seen a 26mm board yet.
Wonder what the current trip point is? Might be great for 26650 IMR cell.

Now I see. Thanks, Rocket!
On the DX forum guys just assume that these boards should be powerful enough, otherwise to sense tu use them.
For IMR's - I don't think so... IMR batteries don't like to be discharged less than 3.3-3.5 volts. These boards, I guess, have approx 2.5 volts threshold, too low for IMR's... Yesterday I asked about using eGo boards as a protection and switch board, but seems that my idea is utopic... It's a pity, these boards have 3.3V threshold

One more thing. There are very cheap protection boards sold separately for 18 mm batteries. Guys say that these boards work with approx 4A current, then trip.. Enough for vaping even you a little boost voltage. They are really cheap, so worth a try...
Charge/Discharge Protective Circuit Board for Rechargeable Li-Ion Batteries (17.4mm*1.9mm) - Free Shipping - DealExtreme
One of these boards works in my light (approx 2A current) - no problem.
P.S. Oh, I deceived you. My light eats about 3A

Here are another LiCo (I think) 25500 (!!) batteries. Protected. Promising for compact mods.

Users say about 4A current with no trip.

Definitely shows a PTC, and then in the notes below says "this battery is not equipped with a PTC."
. Is this also supposed to be the 2000 mAh AW IMR18650? I keep seeing this battery at vaping sites, so the specs., if any, are all copy/ paste and not very helpful, but apparently they both have a 10A max. continuous discharge.Craig is not telling you to leave.

Oh, sorry for the mis-understanding there slimest. I really try not to be a troll, at least not intentionally
CraigHB, no need to excuse. It's OK, I always enjoy reading your information. This is just my poor English, Rocket has more experience talking to me I just thought that you asked me to buy these batteries, nothing more
Just for info: try this: http://www.e-cigarette-forum.com/fo...ego-battery-board-just-electronic-button.html
Very useful schematic. Thanks to jhonutz

Good catch, I would have never noticed that. They go on and on in about their safety technologies that include 3 different acronyms (look at their press releases) and then they put that note in there. Is Panasonic pulling a bait and switch here?
One other thought about the video showing the short test, I dont' know about the Panasonic cell, but I bet the AW cell would have burst into flames using a metal bar instead of a couple wires soldered to the cell contacts. I looked at the video again and noticed the comment about the wires being completey burnt after the test. So, circuit resistance went up greatly as the wires heated up. Shorting with a metal bar would maintain maximum current flow causing the cell itelf to dissipate all the heat. I'm sure the cell would have got flaming hot. A short like that is possible with an all mechanical metal mod.
Yeah, it looks like the new AW "IMR" is the panasonic cell, so I'd expect similar results if/when that is ever done, but dumping 16 Amps from the true IMR vs. the 10 Amps from the "PSS" cell was actually pretty cool to see.
