Did you update to the latest firmware for that battery, is it the V1 [discontinued] or the V2? If V1, I have the same batteries, a firmware was released some time ago, I updated as I use them in a Schneider system. I keep my modules balanced by keeping float enabled, but changing voltage about...
I'm a little late to this thread, sorry about that. I will post all the information I have gathered so far.
I want to make my HA config much more modular, however I am having a difficult time, as I have 3 MODBUS connections; I have a thread here...
Ordered these connectors from china. States 400a, I shouldn’t see these numbers, this requires very little work now.

Congratulations on the modules. I have four of these now that I am working on.
Check out my post I have in these forums, on doing exactly what you plan to do.

Thanks! Feel free to...
I got tired of all the crap inverters out there. GroWatt 12k was beast, but had hardware issues, I tried EG4 6500's as well. The EG4's literaly blew up, so I went with Schneider XW Pro 4868 - Never had an issue since. I'm completely off grid, so therefore dependability is a must.
Quick Update:
Tinned the bus bars/connections. I tried both the Vinegar bath or hydrochloric acid at 10:1 ratio.
The Vinegar gave the best result for me.

Yes, these are supposed to be new never used CATL cells. From what I have seen, I do believe so as well. I was in the same boat, I’m glad I pulled the trigger to buy 4 of these.
Fingers crossed that I do not run into no issues.
Updated Photo's. I am waiting for parts to come in. When that happens the next photo's should contain heat shrink'd bus bars, tinned connections with installed DALY BMS [Temporary]
Or, I wont get that far, time will tell!
I will use a DALY 150 [US stock is avialable] for the time being, as I am torn between the Seplos BMS and the updated PC200: Pace BMS P16S200A

I will tin plate them, I think Tin should be enough? Do you? I will only Tin plate the areas of contact as the remaning area's will have heat shrink on them.
