As written in the title, I am preparing a 24S 5P LiFePO4 battery pack for my e-moped.
I bought 200pcs 32700 cylindrical cells to use 120 of them for this. I will not use 10 of them because of the capacity and IR. (The cells are very bad even though they are brand-new)
I measured the capacity(3,65>2,6@3A) of the batteries, Internal Resistance (AC 1Khz) and capacity loss in 1 month [full charge>1 month later, full charge=delta C](not SoH).
web based Repakr, which works online, uses a single variable (C).
Nemo@secondlifestorage prepared excel based RepakR. This document can deploy using both C and IR. (unfortunately I can't use C-lost here )
1-Is there a reason why the dev-from avg mAh is high at the first S?
2- Would it be of any practical use to use more powerful cells at the most negative in 24S?
3-Is there any problem in distribution?
4-Is there a better way to do it manually in excel?
Thanks for help. : )
