Luyuan battery case

Sorry for bringing my issue here. I started a thread with it but I didn't get the response.
People that are using jk inverter bms (Jk-PB2A16S20P) should help me on how to charge my 1PS16 lifepo4 battery configuration to 3.4v (balance start voltage) and 3.35v float voltage.
I'm using the bms with the Growatt inverter and both of them communicate via CAN protocol. When the battery voltage get to 3.31v the inverter records 99% and stops charging while the bms records 100%.
Is there any other settings to be done?
See the attachment for my bms settings

@ prosier.
You're using Jk-PB2A16S20P and you were able to charge your battery to 3.40v.
Can you show me your settings?
Does your bms comm with your inverter?
If yes, what type of inverter are you using?

If you are using the Inverter Edition BMS and attempting to interact directly with your AIO and what you are describing is discussed in the thread below:

Thread 'JKBMS Inverter Edition Problems/Issues | No Support / Help to fix major issues. - DO NOT BUY ! Warning (as of Oct.12.2024)'

EDIT October 12.
As of Today I changed the title to DO NOT BUY. The ongoing games, misinformation (by JK) and total lack of interaction makes this point.

Interactions with AIO's is NOT FINISHED and terribly lacking and causing issues just like you described and more. Firmware patches have been given but problems continue and now apparently they have come out with a new Hardware Version which supposedly fixes some issues. They now have V14, V15 and now V16 Hardware with these...

Sure, well below my settings. But, first time I had each of my 3 packs live, I had my Deye set to Vbatt, and charged with 70A to 3.45v or so. Then with 20A I set the maximum voltage in my Deye to 56 and I think at the end 57, so each cell is near 3.5v. This way there is no soc-100%-stopcharging issue.

After I did this with each pack, I connected the packs together with the utp cables, set address 0, 1 and 2 on the dips, and connected the utp from master to deye. Then I set Deye to Lithium-00.

Till now, this gets good results, I didnt have (yet) to use the soc-fixer-ghost...

Nice work.
I didn't set the dip....
Is my issue of not able to get my JK PB2A16S20P to charge my battery to 3.40v bulk and 3.35v float related to dip settings as well?
We only set the CAN PROTOCOL 003 and it communicated with my Growatt

So FedEx shows up and is missing one of the boxes with cells in it... Says it is "out for delivery" even though all the other ones were delivered.

It may show up tomorrow. Happened to me once with a multi-parcel package. No explanation. Just showed up.
 
Anybody done/thought about building a unistrut shelving unit to put multiple of these batteries on? I don't like having them stacked one on top of the other and would like enough room above each one to open the case without having to to move it. The unistrut seems like it can be made sturdy enough and also built to use least amount of space. I'd have at least 3 of those 48V Luyuan boxes I want on there.

I have 3 on top. Its moveble/movable.
I have a 2mm wood panel in between so its easy to remove each front panel. Only use side screws for each front panel.

Of course you cant reach the cells but i estimated that is not an issue. If I should, with 2 persons you can remove each complete box if I would need to open up one of the top covers. I dont expect I need to.

Also placed kalium ion fire units in each box. Via Solarassistant and HA I receive mobile phone notifocations as soon as one on the cells goes out of volt spec or out of temp spec.

Please ignore the messy work space. I decided to place high strength aluminum tubes between mine. Basically overkill but they do allow great air flow. These are on rollers and can be rolled out of the project area fairly easily.

Those are some great ideas guys.
I have mine sitting on top of each other.
I really don't think I will ever take these apart.
I had mine operating on shelves without a cases for years.
If I do have to take them apart it isn't that big of a deal

@j_lu, the problem most likely isn’t the settings, it’s the JK PB2A16S20P itself. If you read that thread Steve_S directed you too above you will quickly see it’s a hardware/software issue in the BMS which the manufacturer will not fix. Many of us have the same problem with 100% charging.

Those look nice. Here's a test with a small li-on battery.

 
I know this is safe battery technology . However considering that this type of suppression is being offered in UL approved units it is worth considering. At least in my book. There are those who have been operating for years without any issues. I may pick up a few before Will reviews them and they sell out LOL.
