It can handle more than one JK BMS???Dbus-Serial driver IS closed loop! - It does what the 'Peter Boards' do, just use your own RS485/TTL adaptor.. (Only difference being the dbus driver only works for Victron Venus OS)

Yeah.It can handle more than one JK BMS???
Okay.. thanks for the explanation. I remember now that was what was a bit scary having to use couple different software packages to get it to work with multiple JK BMSs. That just seems to add a lot of moving parts.
Have you tested how reliable it is? i.e. if the OS you are running this on freezes, stops communication, or any other error scenarios?
Someone tried the new firmware.V14.20.
JK PB Series BMS Update FirmwareManual
1. connect PC to RS485-1 port
2. Set DIP 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 BMS
8. click Start Updating or Force Updating button on screen
9. contact JK-BMS through http://www.jkbms.net/contact-us toreceiveupdate code
10. enter code within 15minutes after receiving it
11. PC software is now waiting for BMS to update
12. push BMS power button again and don't release it until youseemessage 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. ReleaseBMS power button
17. be aware, that the BMS has now reset to factor default settings
If you requirement is closed loop, this is already possible with the SOK :So I've been following this new BMS. It looks promising to possibly replace my SOK batteries with it and build new battery packs that will do closed loop to the Sol-Ark. I do want closed loop and that would be the only reason by I would look at replacing the SOK batteries.
There still seems to be some serious firmware bugs at the moment. Hopefully it will be sorted out soon.
If you requirement is closed loop, this is already possible with the SOK :

well, you could simply add to your existing stuff, just make sure you use a PACEBMS and an luyan enclosure as an example.I currently have five SOK batteries and I like the way closed loop works and the information I get using Solar Assistant. I'm wanting to get to 100kWh and I think the best way would be my own battery packs and possibly using this new BMS.

i'm pretty sure you can order them with Amy, and it would prevent capital investment waste
may need to bring them to the same firmware level, but yes , SOK is using the PaceBMSSo the PACE BMS is the SOK BMS? They'll communicate with each other?
Didn't they do a new hardware version recently? Are the early hardware revisions just beta units? Actual prod launch once they are pretty confident the hardware platform is solid?I believe there are issues between Versions of PACE BMS similar to the Seplos ones, where some versions won't interoperate nicely with other versions. I think Andy's Garage & Another had something on YT about that.
On the JK... Being Flash Updatable was a HUGE thing that was demanded by many, because most BMS' out there are NOT updatable with new firmware. JK is indeed being very proactive with their software and have fixed the key parts and are now enhancing & adding support and more "fine details". They really do have to get on the ball with Changelogs, it is clear that NONE of them ever did programming in large software shop where such things are done by wrote without thought, (or else). We even had a rule of code containing at least 10% comment blocks.
But then again, as a retired EMCSE, ECNE, CBE sho started with board level design (control data corp) to core software development & then core networking tech including being a protocols standard specialist for the military, I don't know crap.
I'm entering into the Finalization of my system... years spent getting here... I do not do credit, so it's all cash transactions = patience & prudence all in. The end product will be 44kWh storage with 6 Packs in new, identical Steel Cases and JK Inverter editions. This is being done to simplify by going to a common platform & configuration, for a better "more pro" presentation overall. Being totally off grid, things are to my advantage...I don't mind going with a more flexible BMS. I can probably sell the SOK batteries if needed, but I do very much like them and they "just work". But getting to 100kWh is not going to be cheap and since I DYI everything, I can DIY my batteries too. Though, I won't be building code compliant anymore and that is one worry if I ever go to sell the house.
