I know very little about 18650 but what I do know about are Lipo's

The most basic version a Turnigy 6s 5000mAh 20c Lipo will discharge at 100a constant with bursts at 150a

You can combine these in series/parallel to meet your capacity/power needs

(If you have written this off due to other reasons I apologize for my response)

I just know that these batteries are monsters and when you treat them right, they offer excellent performance

Thanks

God Bless

From the links you provided, go with the Sony US18650VTC4. 16S8P will be 59.2V nominal and 16.8Ah. At a continuous discharge of 130A (which is the max that you want), you should still get very close to 16Ah out of the pack, judging from the graphs of the cell's spec sheet. 55A continuous in an 8P configuration will be a piece of cake for these cells.

I would buy cells pre welded in parelle strips from vendor.
