I do not know how the OP ever got to this reasoning. She has posted about BMSs over 125 times since July (i searched!). Its a shame She did not mention that She was using an iSDT battery monitor thinking it was a BMS; we could have helped Her had we known (first mention of iSDT in post #40 above).
Hopefully Hers cells are ok and She somehow gets a BMS for Her battery.
And she was warned at least 125 times what would happen if she failed to use a BMS. Also she stripped some of the screws but has tapped them.
Ok putting you on ignore for being a repetitive moron. bye
You can put me on ignore too if you like. How do you expect to get any help if you keep putting people on ignore, calling them morons and dicks and whatever? You never know...one of those people you put on ignore might be of great help to you. You claim you are a senior...I am too. I think we should be acting like adults...don't you?
I will throw in my two cents in an effort to help you. And you will not like everything I am about to say because it appears you are looking for someone to agree with you that you have defective cells. I will not be that one. Have you put me on ignore yet...lol. If not continue to read.
In light of the fact all the cells have been through, I would drain them down and the do another parallel top balance. If your cells are not bloated when you remove to top balance then there is a good chance they survived. Take your time and think positively. I know it can be difficult. I felt bad when I stripped a stud in one of my cells. I can't blame that one on the supplier.
Next I would rebuild the pack. I would make sure the terminals, busbars and everything is clean and that you have good connections.
You said the cells were working properly for awhile and then things started to go wrong. Was that before or after you stripped your screws? And are the same cells that shoot up the same ones you stripped the screws? I am wondering if you have bad connections. BTW, what is that red stuff on your cells terminals? Did you use whatever it is to mark your terminals positive?
I will say I am disappointed. In the beginning everyone was warning you about the need for a proper BMS. It's possible you were misled about the iSDT. But when you noticed the cell shooting up the first time, you should have stopped everything then and asked for help.
