Yes, 2 got somewhat pregnant.
Bloated.
Not extreme so probably work just fine.
LiFePO4 isn't lithium polymer, bloating is NOT dangerous.
It will reduce capacity more quickly, and with it less suitable.
The original pictures show bloated cell with the shunt on the negative terminal, and no BMS wires.
New picture show totally different setup.
I'm not sure if it's your personal lab, or professional battery doctors.
The first picture seems the real setup as it doesn't make sense to just remove the BMS lugs and re-tighten the nuts.
Sorry for your 2 cell loss.
Several forum members are happy to receive them if you are planning as landfill.
For initial charge, rules are clear, and discussed many times.
Preferably per cell top charge to 3.65.
If that's inconvenient, use BMS during the charge, and stop when difference between cell voltage appear. (More then 0.1v)
This means... Monitoring, not let alone over night.
And... Lower amperage when the SOC increase.
At supposed 80% full, reduce to 10A max.
It's your first charge, always be careful.
Not boost 70A and expect all to go well.
After that, top charge per cell to 3.65.
Preferably mount then after this In parallel and keep 3.65 from CC/CV charger to get full saturation.
After this, you are ready to go.
Many people have thought this is too much work and tried it their way, with often bloating as result.
I'm one of them
Welcome to the pillow club!
While it's hard to accept you didn't follow the guidelines and that it might be your own fault, especially when you are agitated about QR codes...
This should be seen as user failure....
For now it's totally safe to use the 2 boated cells.
If it's a 12v setup, I would parallel those 2.
You can slowly find replacement from the same or different seller.
If you feel uncomfortable with using bloated cells, no one can help you with that.
They are as safe as they where before bloating, just less capacity or losing capacity more fast.
Sorry, no 5000 cycles on those 2.
I think you need to settle for 1000-1500 before you need to replace them.
That's still 3-5 years on daily usage.
That's why many other forum members do like to get them, preferably for free / postage cost.
Their environment for using the cells is probably more prepared for possible future and won't have harm if it does occur.
