This may not be the same model of cell you're looking, as there are 3 different 100 Ah cells listed, but this gives a good example of what the peak current specs are, and how they derate the lifecycle claims for higher current use.

Amazon actually sells parallel compatible versions of the JK BMS, if you are wanting to do combo series/parallel battery packs
