3400mAh Panasonic NCR18650B

[pabcor]

I dont understand why my previous post disappeared, well, on the website of orbitronic, 3400 protected batteries are available including price

PS: ok, I see that Spain does not stop sending them, I sent mail.

PS2: They told me that it is not possible international shipping temporarily

[ma_sha1]

Phew, that's OK then. I was more than just a little concerned when I had originally thought that you could read it. As long as it's invisible I am absolutely fine with that. Thanks for the heads up!

I couldn't see what you wrote initially, so I sprayed some vinegar on my screen, all of a sudden, it showed up! OMFG, you better delete the post before the mods get out their spray bottle!

These are $27 each on orb...

I would really like to try some but not at that price.

These cells were 'liberated' from a Lenovo battery pack vendor and will be the only supply until production ramps up. Prices will normalize later this year.

But at least that means they're grade A cells, right?

It appears my second post here was lost as well, probably just due to the site going down again.

Basically there is good news and bad news:

Good = the website selling them at such a great price 'bestvaping.net' quoted me good shipping prices too: under $10 for 4x 18650 cells.

Bad = They also told me they have now sold out of the 3400mah Panasonics completely.

Any word on a source for these battery packs?

Not exactly correct information. There are some bare cells floating around in the market, but most are sample quantities of just a few dozen cells. Even most of the suppliers advertising the 3400's don't even have them in stock. I have a couple sample 3400's, and they came at the normal Panasonic ship voltage of around 3.6v and do not have any trace of spot welds on them.

"Even most of the suppliers advertising the 3400's don't even have them in stock."

Yeah, tell me about it! The ones I "bought" from cnqualitygoods never arrived after about 5-6 weeks. When asked, they said there was a server error that had my order listed as unpaid even though I did in fact pay with Paypal. They then said they were no longer in stock (looking at about another month) and I cancelled my order....still waiting on my Paypal to be credited (since July 6th.) I will never purchase from them again.

I bought one of these batteries in cnqualitygoods on June 4. It has arrived without any problem.

[Colonel Sanders]

Lucky you. And I'm still awaiting my refund. Any company that screws my order up this bad and is so slow to refund doesn't deserve my business. They've had my money since June 11th and I have exactly nothing to show for it. I went through the same crap when trying to receive the discount on my Magic Scorpion. I did eventually get it but it took some prodding.

>In the consumer sector, Panasonic’s NCR18650 2.9Ah and 3.1Ah models have used an HRL on the anode and hybrid-type separator with an alumina layer, but the 3.4Ah NCR18650B will not have an HRL on the anode.

In the 2013 catalogue there is an interesting piece of information - currently I'm not sure if this is just a clarification or if the 2013's NCR18650B really have changed:

http://www.panasonic-industrial.com/...nteractive.pdf

- HRL
- capacity 3.350 mAh

Is it sure that NCR18650B released before 2013 missed the HRL? There were some rumors telling so, but I did not find a valuable source for that.

These are my 'unscientific' lux range runtime results for the RediLast 3100mAh 18650 (Panasonic cell) vs Panasonic unprotected 3400mAh NCR18650B

Light tested was a quad Nichia LED dropin 5.6A. Around the 4-5 min mark the outputs pops a little higher for each test because
that's when I removed the light from a flask of ice water for cooling and continue taking its measurement.

So the 3400s both provide higher lux readings all the way through and outperform the theoretical 10% difference in runtime? That's pretty damn good if true. I wonder if a protected cell would have the same kind of performance before protection cutoff. Also, are the Redilasts in the same wear condition as the Panasonics? Since Li-ions degrade inevitably with time, that could tamper with the results.

[tobrien]

so it doesn't make as much sense to get 2600s anymore eh?

[ledmitter_nli]

hehe. yeah maybe?

The RediLasts according to selfbuilts charts are top performers in the 3100 range. I really did the test to see how legit these cells where, and they proved themselves.

@moozooh the cell had about 5 charge cycles. I have 6 ordered in Nov. 2012, so they rotate often and never did deep draw during normal use until this test.

However one caveat:

Fresh off the charger. Not all is as cut-and-dry as it seems.



Imported them from Germany. Unprotected on the left. Protected on the right. Will probably sell the protected since they're unopened.

Do these fit in the Nitecore TM26?

You must use protected, with top button.

Flat top, and unprotected are not compatible with Nitecore TM series.
