Looking for suggestions, Through an apparently bad choice, on my first purchase of 8 Catl 310ah Cells, the cells arrived in bad shape, some with dents in the case, some bent posts, some of them bloated, one of them leaking and unusable.
These were supposed to be Grade A cells, as things turned out it will be impossible to return or get my money back.
I have tested all the usable cells to be 3.2 volts and top balanced them to 3.5 volts successfully.
I have ordered 9 more Catl 302ah cells from a hopefully better source, 8 cells to make up the 24 volts needed and one cell to maybe fill out the questionable original cells and build a 2P8S 24 volt battery.
I am using an Electrodacus SBMS0 so they need to be 2 parallel and then 8 pairs in series.
My Question what do you think would be the best pairing of the cells?
My initial thought is to pair the original cells, then pair the new cells, leaving the one pair of an original and new cell, these would be the individual cells from both sets that matched voltage wise the closest after top balancing.
I understand the Battery pack will only be as good as the weakest pair in the pack.
Just trying to make the best of a bad situation.
