  • Post in thread: Docan Power bad experience, beware.

    And my sad story with BMS order finally came to an end thanks to PayPal protection. They backed my refund request and I received my $1.5K back. One day before the PayPal decision Jenny Wu unexpectedly appeared on Whatsapp after three weeks of complete silence. She made a ridiculous offer that I...
  • Post in thread: Docan Power bad experience, beware.

    Finally I decided to look what's under the black cover of the cells. The outcome was predictable. QR code area looks sanded and I have no doubts the new QR code was printed on top of the old one to hide the "B" mark or to change the product code. It's up to you to decide whether it is a normal...

    And when you see another sweet story about how great Jenny Wu and Docan Power are, don't forget about their very generous affiliate program. You can find it on their website here. "DOCAN POWER affiliate program is free and enables members to earn revenue by placing a link or links on their web...
  • Post in thread: Anybody tried new JK BMS with inverter communication support?

    JK introduced completely new BMS model. You can find it in the Hankzor store here . Active balancing is still there. Support added for main inverter vendors (Growatt, Deye, Victron etc.). It is an interesting product but I am afraid it might have serious bugs in it's first generation.
  • Post in thread: Docan Power bad experience, beware.

    Hello! Having read here on this forum a lot of positive feedback about Docan Power decided to buy from them on Alibaba. Ordered 84pcs of Eve LF280K cells from Docan in January. Sales rep was Jenny Wu. Cells were sold as "brand new Grade A". I paid almost USD12K for them, USD141 per cell...
  • Post in thread: Docan Power bad experience, beware.

    Last month battery sellers from Alibaba were hyperactive desperately trying to sell. Prices are going down already and will continue doing so in the nearest future. Lithium price lost almost 70% since the beginning of the year. We should have more reasonable prices across the board soon. Fraud...

    Only Whatsapp and Alibaba app.
  • Post in thread: Docan 280 EVE cells - 2023 Quality check (update: Bad experience - scam beware)

    After reading this story I realised that I paid $12K to Docan for relasered cells. Too bad this information was not available in January when I placed my order. I could save about $1500 if I just ordered same B cells from Nkon.nl What a waste...
  • Post in thread: MY JK BMS is mis behaving.

    Some JK owners reported latest Android app stopped working. They had to revert to the previous version through apk installer and it solved the problem.
  • Post in thread: Anybody tried new JK BMS with inverter communication support?

    I am one of the guinea pigs))) Already purchased these new BMS. This problem wouldn't be as bad if BMS had LiFePo4 factory default settings. Why JK decided to have Li-ion 4.2V default settings is beyond my understanding. I am sure 90+% of battery implementations are LiFePo4. And LiFePo4 settings...

    No, I was referring to that guy from the video, Ray. In the comments on Youtube he was asked to show on video what is under the black cover but he preferred to leave that question unanswered. And he gave a very detailed explanation how great Jenny is that there are imposters on Alibaba...
  • Post in thread: Docan Power bad experience, beware.

    I can't say $141 per cell was a cheap price. Actually it was higher compared to other Chinese resellers at the moment. I agreed to pay more to Docan because of the positive reviews on this forum. Nkon.nl was selling same cells but with the original B-stamped QR code at $124 including shipping to...
  • Post in thread: Anybody tried new JK BMS with inverter communication support?

    I am ordering now Seplos and Pace based batteries, and also will order new JK BMS to compare all of them side by side.
  • Post in thread: Docan Power bad experience, beware.

    It's not always like this with China. I also had delivery delays with the other Chinese battery seller (Lithtech-Sinorise). Ordered $6500 worth battery packs from them but they couldn't deliver in time, blaming German customs for delay. It took some time but they made full refund even though I...
  • Post in thread: Docan Power bad experience, beware.

    On my pictures here there is a clearly visible oval shaped spot with a parallel scratches, like that area was scraped with abrasive. Rest of the cell surface is even and smooth. I didn't remove the glue, just ripped off the black cover. On Ray's video you can also see that under the glue area...
  • Post in thread: EVE 280K LiFePO4 Cells from QSO/Shenzhen Qishou Technology

    If the seller was honest you would probably buy from somebody else :)
  • Post in thread: Docan Power bad experience, beware.

    You don't need to remove the black cover completely. Just pull gently from one side to the center and then you can push it back and it will stick to where it was originally. No signs of removal should be visible.
  • Post in thread: Anybody tried new JK BMS with inverter communication support?

    How much is this box? Is JK bms communication ports layout compatible with EEL box front panel?
  • Post in thread: Docan Power bad experience, beware.

    Of course I used main Docan account on Alibaba. This one. It's 6+ years old with 749 reviews. There are only two "Docan" named company profiles on Alibaba. I am almost sure second account is also theirs. Often backup profile is created in case main account is blocked.
  • Post in thread: Anybody tried new JK BMS with inverter communication support?

    Dutch Caribbean? You made me cry... For JK I think it would be a smart move if they made layout compatible with Seplos layout. It could help new product adoption. Now there is a new BMS board but there is no compatible boxes available. Please share your experience how all this works.
  • Post in thread: Docan Power bad experience, beware.

    Do you really think Docan is such a big worldwide brand that other Chinese companies make their replicas? I always use Alibaba app or Whatsapp to communicate with suppliers, it's way faster and more convenient than emails.
  • Post in thread: Docan Power bad experience, beware.

    I still have one 4pcs unopened box of Docan cells. Don't want to remove the black cover though as I probably will not be able to sell them.

    Didn't expect forum engine to expand screenshot files to full width, sorry for bad formating.
  • Post in thread: Anybody tried new JK BMS with inverter communication support?

    Has anybody tested whether lost settings bug has been fixed in 14.15 firmware?
  • Post in thread: Docan Power bad experience, beware.

    He created new account. Old account and all posts have been deleted. But he is not active on this forum, only 11 messages, latest one dated Aug 22.
  • Post in thread: Anybody tried new JK BMS with inverter communication support?

    New JK is suitable for proper battery cases, it has communication ports board that you can attach to the front panel of the battery case. And it should be able to communicate to inverters directly, without using any third party solutions. Previous version can't talk to inverters even though it...
  • Post in thread: Docan Power bad experience, beware.

    I confirm that. They call it DDP but actually it is not. I asked Jenny Wu this question about VAT, she answered there was no way to use or refund their so called VAT. They can just print VAT amount on invoice and that's it, it is not properly paid and registered in the VAT database. Also I...
  • Post in thread: LiFePO4 Cells - Shenzhen Hongxinda New Energy Co. - Alibaba

    2.8cm maybe? Definitely there is no need to drill as deep as 4cm, 2 cm should be more than enough. So you damaged the first cell and then did the same to two remaining cells? Once I considered buying LF280K cells without welded terminals from NKON but I have access to laser welding, would prefer...
  • Post in thread: Docan Power bad experience, beware.

    Yeah, that's a problem that Alibaba protection in reality is nonexistent and remaining options are not great.. I already used majority of the cells I purchased from Docan. Assembled batteries were handed to my customer already. They are under very light load now, mostly in standby mode. We had...
  • Post in thread: Docan Power bad experience, beware.

    Yes you can see that color change but it's not easily noticeable. It's when you remove the black cover you can clearly see that sanded spot. Please share QR code pictures when you get your cells. Who knows, it's possible that US market is in a privileged position compared to European and you...
