i’m also interested in trustfire IMR-batteries

Sanyo 18650GA 3500 mAh

edit: NKON has it in stock.

If possible I think HKJ would appreciate a link to the requested product, if possible to somewhere that has cheaper shipping to Europe.

Thanks HKJ. I look forward to ALL your test results.

With respect to you, This will be the only comment on any of these until your done testing!

I will say this about one of them N’Core 16340 NL166. From my own experience[piece of junk!] and a German company that tested it, I will be shocked if you get good results! Rated at 650mAh they got 18mAh actual capacity!

^^^^ Sorry,,I should have noticed this!

I was wondering why they did not use 2 cells like you. At the end they said,,,,,,

Despite the fact that the PCB didn’t trigger, this cell cannot handle the 2A currents we vapers need. Perhaps this test needs to be redone with fresh samples.

Request suggestions:

IKEA LADDA AAA NiMH

Edit: Sorry didnt noticed the other thread Off topic, but IKEA now also have a 3 port USB charger Max 3400mAh total and max 2400mAh on single port, named KOPPLA. Maybe something for future testing? The price is 79 SEK or about 9 USD (actually it´s 9.99 on the US site)

Thanks for all your work!

Kind regards

I can’t wait until you have reviewed these, because i have so far not bought a battery you haven’t checked out yet

LG INR18650 MJ1 3500mAh

Samsung INR18650-35E

LG INR18650MH1 3200mAh

Sanyo NCR18650GA 3.6V 3500 mAh

And because the Windyfire 14500 10A batteries was great, i am really curious about these……..

WindyFire IMR 18350 700mah 3.7v 10.5A

Windyfire IMR 18650 2500mah 3.6v 35A

I for one am more than willing to buy some cells and ship them to HKJ.

For example..

• Tenergy 4/3 AF Size (18650) 3800mAh NiMH Rechargeable Battery

• Titanium Innovations 4/3AF (18650) NiMH battery 4500mAh Flat Top

• Tenergy 10511-0 NiMh Sub C Flat Top Batteries

We all know at least something about the name brand Li-Ion cells but know nothing about the NiMH in sizes normally found in Li-Ion cells.

The question I have is how many cells are needed for proper testing - 2?

I will not ask anything , I just want to thank you for your assistance and your trouble my friend.

Always be well ΗΚJ

I have tested them, with my REAKTOR and they are very very good, if you wish I could publish some graphs

Hi HKJ, do you have anything you could review to help shed light on this thread regarding Protection IC added to stock 18650 manufacturer's cells.

http://budgetlightforum.com/node/40248

I've quoted my original OP below; I think many of us would be interested in a teardown of the quality and effectiveness of the retro-fitted protection circuits, as much as the cell efficiencies.

There is a lovely thread I found here by RMM of Mtn Electronics, for the protection circuits used by Keeppower (widely considered the gold-standard of Protected 18650 cells), http://budgetlightforum.com/node/26090

This is a teardown with pictures of the Panasonic NCR18650B cell as wrapped by Keeppower and EVVA; with the inclusion of their Seiko protection circuits and button-tops.

It would be great to see something similar with these 'stock' unbranded re-wraps, as obviously not all protections are made equal...

Hi fellow BLF'ers,

Like many cautious of the risks inherent with Li-Ion cells, I am a supporter of Protected cells, especially when introducing our favourite high powered flashlights to beginners. We do recognise there is a time and place for unprotected cells, such as when dealing with high-current requirements, IMR, or some newer hybrid chemistries INR, NCR, etc.

(I think the rule is a little like sex :- always practice safe and use protection unless you want to produce some specific results!)

 

My personal preference is for protected batteries purchased from reputable resellers such as NiteCore, KeepPower, AW, XTAR, EagleTac, AWT, EnerPower+, and EFEST, amongst others.

 

These suppliers may add protection circuits, either of proprietary design (such as AW does), or provided by reputable suppliers (SEIKO is used by NiteCore). They might also modify the ends to provide a button-top or metal base plate under the protection PCB. The actual cell manufacturers (Panasonic/Sanyo, LG, Samsung, Sony, etc) do not afaik make protected cells themselves. Most don't even produce button-tops. 

 

However, we frequently see coloured cells sold by the usual Chinese stores (GB,FT,BG,etc) listed only by the original cell manufacturer, but with protection included. I believe it is likely that the protection IC was added by a third-party and minimally re-wrapped to remain as similar in appearance to the original manufacturers colour wrapper as possible.

 

This opinion is based on the information provided by HKJ who states here http://budgetlightforum.com/node/17862 regarding the ’Panasonic NCR18650B Protected’:

“This battery is not made by Panasonic. The cell inside the battery is from Panasonic, the protection cirucit and the assembly work is done by somebody else.”

The sellers do not mention this fact and sometimes even use terms like "Authentic"; language which would further give the false-impression that the entire protected battery was made by the stated manufacturer. (My own opinion is that this is intentionally misleading).

These appear on nearly every seller’s site as a stock 18650 cell with the manufacturer’s original coloured wrapping, text and markings. Except they now have the addition of Button top (optional), Black 2-3mm plastic base (containing the IC), visible metal strip running down the side, with orange insulation tape over the metal strip. This style protection is identical regardless of the original cell manufacturer, lending further evidence to it being added by a common third-party.

 

There are some questions that seem to remain unknown:

• Who is adding the protection circuits to these cells?
• Do we know where the IC is made (Japan, China, Korea, etc), and by whom?
• Is there any evidence of the effectiveness or longevity of these protection boards?
• Are they always protecting against the critical three: overcharge, over discharge and short-circuiting?

 

Without knowing this information I would rather have quality and trusted protection IC added by the likes of NiteCore, Keeppower or EFEST, (preferably made in Japan), than an unknown IC added as an aftermarket mod to something that just appears to be from the manufacturer.

Hope this provides a useful discussion point and can possibly resolve some questions in which others may be interested.

 

Keep shining,

Hirsh

philips lithium primaries

any better than energizer lithiums?
hope you can test these out

I have tested the Windyfire and will publish them when I am finished with Shockli

The rest goes onto the todo list.

Thanks

+1 on the Soshine 26650 5500mAh, they seem really good from n10sivern’s test of them. If you could i would be very interested in the performance both with the protection & with the protection removed.
And @ DX you can find them much cheaper than that https://www.msitc-shop.com, that was just ridiculous expensive for a single 26650 battery………

And +1 on the green Efest 26650 4200mha battery, Mitko’s testhas indicated that it is possible the strongest in single 18650/26650 batteries 5-7A flashlight applications of any high drain battery with a DD driver & full round of low resistance mods and even stronger than the Efest purple 26650 4200mha & Efest purple 26650 3800mha.

I don’t want to miss out on any of your future tests, so wonder if you maybe could have a mailing list or something similar, so we can get a heads up when you have published new tests.

Soshine is already in queue, I bought them from fasttech.

I can’t find them @ fasttech?
Can you give me a link to them.

Would you mind taking a look at a protected version of the Sanyo 18650GA battery as well?
Like keeppower bought from Nkon?
Thanks

You are correct, I just saw the white label on the envelope, but it was not a fasttech label.

I got them from ebay.

I can’t find them on ebay either……the only 5500mha 26650 battery i find on ebay is TangsFire
