    Where does it mention a "Panasonic"?????????????????????

    3400mAh it is a very high capacity. I doubted it is 3400mAh.

      Battery is listed as brand panasonic in advert. But the protection is not panasonic. They are good batteries.

    • alexwang110 on 01/03/2016 - 15:02

      thats panasonic 18650 battery if they took pic from the other side it has there name in front…

        These usually arent for the average person, so there isnt any need for them to write "Panasonic". Besides as dyl mentioned later in the thread "NCR" is usually their identifier.
        Now that said, anyone can shrink wrap "NCR18650B" around a 18650 sized cell so whether they are legit is your own risk. (There have even been similar shrink wraps seen on alibaba!)

        However I have baught this same set from Banggood before and they have tested to be ~3400mAh on my hobby chargers(give or take a few mAh if you decide to charge/discharge at faster rates).

        Also as Gofast mentioned, the protection board (the little black part at the bottom of the cell) is not by Panasonic. It is later added to the cell just for consumer use. You may easily remove it if you wish, just be aware that the tab to the positive terminal may short with the battery's negative casing.

        Edit:Forgot to mention the addition of the protection board adds ~2-3mm to the length of your normal 18650. This may prevent it in fitting into some devices.

      • frondono on 01/03/2016 - 15:12

        These are legit batteries, the same that tesla use to power their cars.

        I think they might use the 2900mah models though.

        NCR18650Bs are well-known cells. 3400 mAh is their nominal capacity.

        Whether these are legit NCR18650Bs, on the other hand, is debatable. But IIRC Banggood is usually fairly trustworthy for this kind of thing.

    There is some risk these will never arrive, since most postal carriers will not accept such lithium cells.

      Bollocks, I've ordered two sets of four from GearBest already this year and both have arrived and the dozens I have ordered over the last few years have all arrived.

      Not every postal service is as screwed up as Australia Post and they carry thousands of lithium batteries every day without problems.

      However people who are experienced with these things will already know that.

        What has Australia Post have to do with the price of fish? Hong Kong post, Royal Mail, UPS, FedEx, DHL, and a multitude of international carriers have strict regulations or will not accept Lithium batteries either.

        Generally, if lithium batteries are detected during routine scanning, they will be confiscated and destroyed. However, from my experience this is fairly rare.

        || However people who are experienced with these things will already know that.

        Surely my comment is simple enough to understand? People like yourself who are experienced with importing lithium batteries know that there SOME risk that they may never arrive.

        People like yourself who are experienced with importing lithium batteries also know that the majority of orders arrive just fine. Therefore, we accept the risk because the far lower cost from overseas makes it more than viable.

          Because Australia Post are a joke, they made a knee jerk reaction to stop the sending of any lithium products (including button and calculator batteries) whilst still distributing them from incoming mail using the same network in much larger volumes. They essentially shut down many small businesses for no reason all because of a report from the ITU regarding the sending of large commercial quantities (think hundreds of 18650 batteries in a single box).

          You said most postal carriers will not accept Lithium batteries but this is not correct.

          Generally, if lithium batteries are detected during routine scanning, they will be confiscated and destroyed. However, from my experience this is fairly rare.

          But they don't be because it's legal to send them from outside Australia. I've sent hundreds over the last few years and never had one detected so this scanning they do is pretty useless! I've also received dozens from inside Australia.

          Surely my comment is simple enough to understand? People like yourself who are experienced with importing lithium batteries know that there SOME risk that they may never arrive.

          The risk is minimal and more to do with postal theft than detection of Lithium.

          People like yourself who are experienced with importing lithium batteries also know that the majority of orders arrive just fine. Therefore, we accept the risk because the far lower cost from overseas makes it more than viable.

          Actually getting them from overseas is the most legal way to do it given the ban on Lithium by Australia Joke.

          Like many other postal carriers who do not have the ability to comply with the International Agreements and policies on air cargo. Lithium batteries are classified as "dangerous goods" and are required to be declared and transported safely. It's the exact same policies that prevent you from legally posting aerosol cans, or bottles of petrol either - yet both of these are perfectly safe in normal use.

          More info: http://www.iata.org/whatwedo/cargo/dgr/Documents/lithium-bat…

          You said most postal carriers will not accept Lithium batteries but this is not correct.

          Please show me a couple of examples of postal carrier services / countries that accept loose (not within devices) Lithium Cells in general airmail without special inspections and handling.

          No, I don't mean couriers like DHL who have the systems in place and will carry them providing the correct paperwork is provided.

          But they don't be because it's legal to send them from outside Australia.

          Oh, you mean with a false customs declaration, and not declared as dangerous goods?

          I've sent hundreds over the last few years and never had one detected so this scanning they do is pretty useless!

          Yesp I agree. Yet they have the technology to detect and confiscate almost every laser pointer. The mind boggles, eh?

          I've also received dozens from inside Australia.

          Of course, because there is no restriction on sending them by ROAD.

          Australia Post made a knee jerk reaction to an IATA advisory regarding the sending of BULK shipments for commercial use in 2009 and were the first to ban lithium battery transport via AIR despite carrying them via AIR when they are sent to Australia. Many years later a few other postal services have done similar.

          Most of them.

          They don't need to be declared to most services.

          Not every laser pointer is detected, it's not hard to send them in so the can't be picked up.

          None of them were sent by road and this includes 5Ah 18V batteries for power tools.

    These are great batteries for low current applications.
    Something to note is that if they are in fact protected, they will be closer to 70mm, not the above indicated 65mm (65mm is for UNprotected batteries)

    • Russ on 01/03/2016 - 17:12

      Description above has different dimensions to the webpage, says "6.5 cm x 1.8 cm".

      The webpage says "Size:69.6mm x16 mm", and one of the photos on the webpage shows the difference in length that you mention.

      Another photo shows digital calipers, giving the diameter as 18.12mm, so the description on the webpage is wrong too.

      Which of these measurements are correct?

    • troyww on 01/03/2016 - 17:22

        For e-cigs you want IMR. Lower capacity, but safer than ICR (including these NCR18650s) and can sustain larger currents IIRC. But that's just what I've heard in passing - I'm a torch guy, not a vaper.

  • murkywater on 01/03/2016 - 20:25

    Very good price, just be aware that these are some of the biggest protected 18650s you can buy, and you might have issues with fitting small flashlights. That's why I spend more for Keeppowers and other alternatives that are <69mm length.

    • GreatWhiteHunter on 01/03/2016 - 20:51

      I actually have the opposite problem with smaller batteries - my flashlights wont work with the smaller batteries, in particular those that are not button-topped…

      • murkywater on 01/03/2016 - 21:03

        Yes that's another issue, some flashlights won't work with flat top batteries. You can usually fit a small magnet to get flat tops to work in those flashlights. However, nothing you can do if the flashlight won't fit these massive batteries.

        I personally haven't had any issues with my button-top keeppower 3500mah that are 68.9mm in length. Evva 3500mah and Blazar (from ebay) are also the same thing pretty much.

        • elusive on 04/03/2016 - 18:45

          If you use the magnet trick, make sure you put a dab of glue (hot melt, epoxy) on the side to hold it in place. If it ever slides and shorts against the side of the torch body… yea you don't want to have to deal with that.

  • GreatWhiteHunter on 01/03/2016 - 20:33

    Just be aware Banggood can be difficult to deal with at times.

    2 of my recent experiences:

    1) Ordered similar batteries on 6 February 2016 - they still haven't even got out of China yet according to the tracking

    2) Ordered a Klarus C8 charger (http://www.banggood.com/Klarus-C8-8-Slot-12V-Multifunction-L…) on 2 February 2016.
    It arrived about a week later, but without the necessary AC adaptor to run it (it should come with an external power adaptor). Emailed Banggood, no response. 2 weeks later having received no response from Banggood I raised a PayPal dispute, they contested it.

    I personally have lost a lot of trust in Banggood as a result…

    I would also say I bought some similar Samsung batteries recently from Fasttech.
    https://www.fasttech.com/p/2706600

    Having used them in my HC30 headset I know for sure they are fakes. After about 10 minutes use the brightness of the light drops to about 1/4 of it's initial brightness. It seems these "Samsung" batteries cannot sustain a reasonable voltage output for more than 10 minutes…

    I have similar NCR 18650B batteries to those listed here which are genuine and they are very good.
    if you shop around for coupons you can get them cheaper than the price listed here.
    The ones I bought were these https://www.fasttech.com/p/1345500

    I cannot list the coupon code I used because the poster on BLF forbids publishing the code on other sites, but you can easily find it yourself on the Budget Light forum web site.

          If you are careful not to short the battery when installing them it should be fine. If you're using them with a powerbank circuit the protection is (normally) on that board.

          Though its normally cheaper to buy unprotected cells in the first place.
