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...

Has anybody tested whether lost settings bug has been fixed in 14.15 firmware?

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...

If the seller was honest you would probably buy from somebody else :)

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...

Could you please share details of your cell purchase from the warehouse in Poland? Which company sold you those poor performing cells? Please post photos of your cells. I am asking because I ordered test batch of cells from the warehouse in Poland. They are with the same sticker as on the photos...

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.

I am ordering now Seplos and Pace based batteries, and also will order new JK BMS to compare all of them side by side.

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.

How much is this box? Is JK bms communication ports layout compatible with EEL box front panel?

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.

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.

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...

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.

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...
