While updating one of my new JK Inverter-BMSes to the latest firmware, the flashing progress stopped at 4% and never finished. It was unresponsive, didn't show any sign of life neither in the PC software nor the Bluetooth app. The BMS was bricked!
I tried to work things out with JK but never got behind the real process and workaround to recover the BMS.
Thanks to one of my viewers who had the same issue, we had success in recovering our both BMS by following the below procedure. It is very important, that during any firmware update, no second BMS is connected to the one you want to update. No master, no slave...
1. connect PC to RS485-1 port
2. Set DIP switches to 1000
3. turn on BMS with power button
4. start PC software
5. select 3 vertical dots in the top right
6. select Upload Firmware
7. select correct firmware file for your BMS
8. click Force Updating button on screen
9. contact JK-BMS through www.jkbms.net/contact-us to receive
update code
10. enter code within 60minutes after receiving it
11. the PC software is now waiting for BMS to update
12. push BMS power button again and don't release it until you see
message under 16.
13. push reset button on BMS communication board once
14. confirm that firmware update starts through PC software
15. keep power button pushed until firmware is successfully updated
16. confirm firmware update successful! message on screen. Release
BMS power button
17. be aware, that the BMS has now reset to factory default settings!
Thanks to Stephan for helping out and developing this procedure.

Hi Andy, I have a JK-PB2A16S15P V15. I have a minor issue with the app in that it shows only 1 column in lieu of 2 like it did originally (takes some getting used to). It's OK when I turn my phone to landscape (same with other phone). I thought I would let you know that I tried all your efforts to default the JK but with no luck, I even bricked it & brought it back. The JK came with V15.10, worked OK, immediatly upgraded to V15.11 (tks to you) & now have upgraded to V15.17 still shows 1 column. Cheers.

@mobracska 3 месяца назад

Just my 5 cents to this topic: I had a very hard day today ... tried an update, it failed, bricked the bms ... and after a few hours of unsuccessful trials to force update, i had an idea: what if some electric device is creating some electromagnetic noise which is ruining the RS485 communication? Turned off all devices (including my laptop's charger) ... and the force update was successfull.

As mine is exactly this model

@OffGridGarageAustralia 5 месяцев назад

I have heard from other that JK is sometimes using just red cables without any black one. I never heard about two black ones though. I would just connected them as usually, first one is bat-, next one is bat1+, next one is bat2+,... The BMS should also come with a manual and some diagrams on how to connect the BMS. Follow that recommendation.

Hello, I want to ask you a question I bought two 100A lithium batteries, two years ago one has just stopped working it charges up very quickly and then discharges very quickly so I have just taken it apart. it looks very good quality inside there is no BMS is this normal I’ve never seen this before I could send you a picture if this is not normal so I’m also wondering about the other one. Is it safe to use it. I’ve looked at battery tear down on RU-vid and everyone seems to have a BMS. Is it normal for a battery not to have one? Thank you to anybody that answers.

@OffGridGarageAustralia 5 месяцев назад

If you are talking about the normal 12V LiFePO4 batteries, they have to have a BMS. There are 4 cells inside the box and there MUST be a BMS as well. If not, you can be lucky that none of the cells has gassed yet. Most likely, one or more of the cells is now damaged and hence the voltage drops quickly.

@nuwanfernando339 21 день назад

I also had a "double bricked" PB2A16S15P (force update also failed). JK BMS support was not of much use. By trial and error, I got it working today. 1. Turn off the BMS - disconnect all power. 2. Connect the RS485 cable to computer and BMS and start the JK BMS software and do a force update with the BMS still off. 3. Connect power to the BMS (I used a power supply to B- and B+ without any batteries). 4. Press and HOLD the power switch. In my case, the BMS powered on and the force update completed - saving my BMS. I hope it works for you too.

I don't understand why the JK code would only work for an hour. The bricked BMS does not know what time it is and how much time has passed since the code was generated. It even doesnt know which time zone in the world it is in. I would imagine that if you disconnect the PC you are using for the update from the internet then the code could be used indefnitively.

@OffGridGarageAustralia 5 месяцев назад

The BMS does not know, no. But the software on the PC has got the time from the computer. And yes, you are right, some here have already done that and set the time back and it seemed to have worked.

You'd think the windows program would be able to generate the code for you, or at least retrieve it :)

Hi, hast du das am 14.12. gemacht? Ich mein ich könnte da eine Logik in Code erkennen. Möglicherweise red ich auch total Schwachsinn 😂 aber es wäre ja zumindest ein Versuch, die nervige halbe Stunde selbst zu berechnen und den Code selber zu erzeugen.

@OffGridGarageAustralia 6 месяцев назад

Do it!

What is "Bricked"?

@OffGridGarageAustralia 5 месяцев назад

Not responding any more. Happens when the update fails half way through.

Thanks man 👍!

Hallo nach Australien ! Ich bin Johannes- leben in Montenegro und würde mir gern eine DIY Batterie Box -280 ah-48V zusammen stellen. - wozu würdest du mir raten! LG Johannes (Rentner 64)

@OffGridGarageAustralia 5 месяцев назад

Die Seplos Mason oder EEL Batterien sind dafuer sehr gut. Hab viele Videos darueber gemacht. off-grid-garage.com/diy-kits/

It's stupid as hell that you need an unlock code and it is time limited. Why do they need to make it that hard?

@andreasw5925 6 месяцев назад

For all the customers that downloaded the wrong firmware, that want to force the update despite the warning it’s the wrong firmware and then blaming JK / asking for replacement or support.

Once the company goes tits up, those bricked cards are problem waste.

@OffGridGarageAustralia 5 месяцев назад

I guess, JK is here to stay. I can't see them failing and not selling BMS any more. Also, we now know how the code works...

@tomassliauteris884 6 месяцев назад

Maybe with this brick you can downgrade. Please try it. Thanks in advance.

@OffGridGarageAustralia 6 месяцев назад

You may need a code again...

@The-JMartian 6 месяцев назад

Don't know if worth the time . What about you test some cheap BMS for us that are living in a budget

@upnorthandpersonal 6 месяцев назад

Regular JK BMS is about as cheap as it gets. JBD is another option.

@OffGridGarageAustralia 5 месяцев назад

I would not recommend any BMS which does not have Bluetooth function and you can set the settings as per your needs. Yes, they are cheaper, but certainly not worth using. You never know what they are doing and what settings and safety functions apply.
