    they look great!

    Another flash manufacturer copying from the Godox Ving V860II, great move to the battery pack, next YN introduce your version of the Godox AD200, competition in the market is getting hot.

    • Ryan Lindsey 4 years ago

      As someone who recently moved from Yongnuo to Good because of these batteries, good on them!

      I may not switch back (Nikon shooter here), but I much prefer the Yongnuo transmitter controls to the Godox ones.

      Yongnuo has easier power adjustment, a bigger screen, and can change the mode of the slaves from the transmitter.

      I think they’ll copy the AD600 first, since they already have the YN-300W.

      • sceptical1 4 years ago

        Hi Ryan,
        I was using the Yongnuo 622TX transceiver with my Nikon and Metz flashes. I also had two Yongnuo 685’s. I felt their controller was better then the very expensive Pocket Wizards for a fraction of the price. They just proved to be soo reliable. Also, I had great luck with the 685 flashes. Like you, I decided last December to replace everything – strobes and flashes – with Godox (Flashpoint rebrand). I wanted strobes and speedlights to work reliably off the same controller, I wanted Lithium batteries for everything, and I wanted everything to have a built-in radio.
        It was a great decision in general. The Godox gear is well built (I have dropped one on the cement from a lightstand and it still works fine) and very reliable. That said, the X1 controller just isn’t as good as the Yongnuo. The X1 controller is less straightforward, the display is dimmer, smaller, and harder to read (especially in bright light). This is actually a fairly big deal. If Yongnuo had had a comparable system to compete, I would have stayed with Yongnuo just because of the better controller.

    Make a speedlight that can be tricked bt the air remote from Profoto, please..=)

    • sceptical1 4 years ago

      Why I didn’t go with Profoto. I want everything to work with everything and I am willing to sacrifice a small amount of light consistency to get that. It also doesn’t hurt that the alternatives are also cheaper (not a deciding factor, but who is against saving a few bucks?).

    Ok who is going to try these batteries first ? 🙂
    Good move by yongnuo it will sell like crazy

  5. Kris 4 years ago

    Pity it does not have the External HV Battery Port.

    • Alfonso A. Tobar 4 years ago

      Please, reread… “600 hundreds full power pops…” What do you need an external power supply for? The key word is T.H.I.N.K.!

      • garethq 4 years ago

        For quicker recycle; stop being condescending.

    • Mark 4 years ago

      With a Li-Ion you don’t need an external pack. Recycle times and number of pops will be way better.

      • Author
        Flash Havoc 4 years ago

        Actually a lot of people have been asking for an external battery port in the V860II. The Lithium-ion battery is great, but there are times people still want faster recycle, and using a PB960 etc with a conventional speedlite the recycle times can be less than half that of the V860II.

        The big restriction then is still heat protection though, and Canon and Nikon are a way ahead of Godox and YongNuo etc there, though hopefully the coming Nissin flash may be something special (at a price).

        It all depends on how much speed and power you need though.

        • adam 4 years ago

          Sometimes I will use the 685s with the HV pack but most of the time I will just settle on the 860s or move up to the ad200/360. I would def buy a 860 with a lithium HV jack. Especially if they made a small pack like the pixel one coming soon.

    Is this the same battery as the Godox?

      Hi Ed,

      No its definitely not the same as the Godox battery.

      • ed 4 years ago

        Thanks !!!!I I would have bet it was the same *LOL*You would think. It looks like they went with a slimmer battery which would make sense.

  7. jim 4 years ago

    Make a flash that doesn’t overheat and has a powerful AF assist beam that can focus in pitch black.

    • Roman 4 years ago

      You definitely right! when they start to work on AF assist beam??? It’s much more important i think.

  8. Anthony 4 years ago

    I just hope they don’t constantly overhead like the Godox flashes

  9. jim 4 years ago

    The first YN600 overheated and stopped working. I threw mine out one time after it let me down in the middle of a gig. Never again!!

    Is 1 2000MAH lithium better than 4x 2500 mah Eneloop batteries ?

    • Author
      Flash Havoc 4 years ago

      Hi Kevin,

      YongNuo haven’t stated the voltage of their battery yet so I couldn’t quote that either, though you need to take the voltage into consideration as well as the Amps.

      If they are 11.1V like the Godox batteries then they will have the capacity of around twelve 1.2V 2000mAh AA batteries. (600+ shots).

      • Chris 4 years ago

        It’s 11.1V just like Godox.

    • sceptical1 4 years ago


    • Walter 3 years ago

      11V x 2A=22W
      5V x 2.5A= 12.5W

  11. jim 4 years ago

    the only thing about these flashes is that you have to buy a second lithium battery as back up, I hope they are not too expensive.

  12. Benson 4 years ago

    Hi, I’m an Yn600ex-rt user and I underwent overheating problem a few days ago. I had to cover a ceremony outdoors. The sun was hot and I had to use the flash frequently againt the sun. The flash showed overheat signal and slowed the work. I’m looking for a solution. Would this Yn686ex-rt be an answer? Or any other suggestion such as godox flash, please?

    • Simon 4 years ago

      Do you mean yn600ex-rt or yn600ex-rt ii?

  13. jim 4 years ago

    Benson, the YN 568ii is quite reliable and doesn’t overheat as far as I know. I have 3 copies and its sturdy enough. Better than its successor, the yn600, that was a godawful piece of crap.

  14. Marco 4 years ago

    Definitely a good move of Yongnuo. As a owner of their YN-622C TX I’d consider replace my 568II. But I’ m even more interested in a Cordless YN 300-500W Li-ion powered portable studio unit. That would be a killer unit. I don’ t wanna sell all my YN triggers to switch to Godox XT1…

    • sceptical1 4 years ago

      I got tired of waiting for a complete system. Godox had it and I switched. Such a good decision, despite the X1 controller not being as good as the YN-622.

  15. jim 4 years ago

    still not released. 🙁

    I saw this Canon version on sale on ebay for AU$200. About when we would have Nikon version?

    • Author

      Hi James,

      I really don’t know. I would imagine YongNuo would take some time to see how the first version and batteries etc hold up.

      Then chances are they would likely do the YN622 version next, in which case that’s usually the Canon version first as well.

  17. Greg 4 years ago

    looks like it’s a new yongnuo flash.suit for Nikon D5500?

  18. jim 4 years ago

    Who is in charge or marketing and PR at Yongnuo? Seriously, its for sale on ebay and there’s no review videos on youtube or anything. FH should have gotten a copy to review as well, because a lot of us make buying decisions based on what we read here.

  19. jim 4 years ago

    any reviews?

  20. jim 4 years ago

    Is this compatible with the 6d?

    • Simon 4 years ago

      Absolutely , yn686c is compatible with 6d ,5D iii, 5D IV, 5DSR etc.

  21. jim 4 years ago

    Will Yongnup send the website a copy to review

  22. jim 4 years ago

    did anyone here get one?

  23. Paddy 4 years ago

    Hi there,
    Is this flash compatible with the 622c-tx


  24. Author
    Flash Havoc 4 years ago

    Hi Paddy,

    It should be, provided you attach a YN-622C II receiver to the flashes foot though.

    There is no YN-622 radio receiver mode built inside the flash.

      Hi David,

      I’m caught up with the larger strobes at the moment, so I’m not planning any in depth reviews at the moment. I might pick one up though and see how it goes.

      Like with the Godox strobes though I think we need to hear from a number of people to know how the batteries are holding up. And less comments can actually be good news there.

      • david 4 years ago

        ok thanks.

    ¿Alguien tiene conocimiento de si está disponible el manual de instrucciones en español?

  27. Mark Hillis 4 years ago

    Does this AF beam turn on/off when you press/depress the AF button….that’s not the case with the Godox V850II.
    With the Godox V850II speedlite you have to manually turn on the AF assist beam and then wait for it to turn off (appearing in any shots you take with slow shutter speed or high ISO). You can set it to turn off 10, 20 or 30 seconds after you take the shot (how weird!!!). Yes, you read that correctly!! This doesn’t work with event photography at all! Just bought the flash and couldn’t believe it. Does this flash turn on/off the AF assist beam when you press the AF button like flashes are supposed to do? That was a deal breaker for me for the Godox V850II.

    Not related, but for the mod to read and consider an article on here as to where we are with flashes? Not much news from canon or yongnuo lately as regards new flashes, so is there little or few advancements that can be made? For YN flashes, I’m hoping they really improve the AF beam points or selectionon flashes so they can near focus in near dark or even dark conditions, ie niteclubs etc..
