18650 100amp discharge

Looking to build a 13s 18650 pack @ 13.5ah.

The only hitch is that it needs to have a max discharge rate of 100amps.

Coming from Lipo cells I am in new territory here, so any advice is appreciated.

It depends on your budget or course, but if you are going with a 7p pack, any 18650 over 15ah discharge should do it.

Something like a Sony Konion US18650VTC5A 2600mAh - 35A would surely do it at 6p.

Peak or constant discharge?

You'll likely be limited by how much voltage sag you can tolerate before the cells over heat.
