Replaced Bad Cell but Still Get Triangle of Death

First of all thanks in advance to everyone who leaves useful, productive responses. You all have saved me thousands of dollars before, despite the responses of some people who say that it was hopeless, so thanks.

Ok, so I replaced a bad cell after getting a P3022 code 'Block 12 becomes weak'. What happened was the car was driving fine, then all of a sudden would lose acceleration power. This is before replacement. So then I looked ubder the battery cover and noticed burnout (as seen in the photo) coming out. I also noticed the bus bar was blackened. I ordered two new cells to replace block 12. The voltage without load of the bad cell read 6.2 v. Bad indeed. I would be able to drive it for a mile or two, but then something would trip, then acceleration power became weak, and the triangle of death would activate.

After installing the two reconditioned cells it still happens pretty much like above. Now thanks to the PC forum, last march I was told how to replace a reverse polarity problem and burnout of a few pins in the male Wire Frame #2 terminal. This time there is no reverse polarity or burnout in the male piece. The burnout is in the wire frame #2.

Silly question: Is there a good likelihood that Wire Frame #2 (part #8216547040) needs to be replaced even after the cell? Perhaps there a crack in the wire plate or something that I can't see? Is there any possibility (if the problem were indeed with the HV Battery) that something else could be the problem? The code tripped after replacement was the very same thing as mentioned above (P3022 - Block 12 becomes weak).

many many thanks to you all

Just FYI, I did clean off the bus bars and nuts as much as possible.

No I ordered it and the seller reconditioned them, or at least they said they did. I honestly don't see an issue with the cell itself. I haven't checked the Techstream yet for it, but I will and if I see something then I'll know. But I did order a wireframe. There's probably a micro-abrasion or fracture that's causing something to go haywire.

 

Thanks everyone for the response. So I tried balancing the modules by placing them in voltage-ascending order. That made it a little better but now the batter gets weak in other areas. I'm considering just buying a used battery on eBay, one with a return policy if it's defective or doesn't work in my car. I am also considering just buying a decent sized RC charger and reconditioning it myself. The problem is I damaged the temperature sensor wire "A" while doing the balancing and have to replace it. I will also need to replace that wire harness, so either way $500-$1000 for sure.

I'm a little cautious on the reconditioning of it myself because if it fails, then I'm out $300-$400 and still have to spend another $1000 to get a used battery.

Any suggestions? Just go with the used battery? I can't do $2500 for a new battery. That's too much for me right now.
