Hello guys,
After reading some posts here, i couldn't find a definite answer on my question.
I'm planning on building a stealth bomber clone e-bike with QS205 4T V3 motor and Mobipus 72200 controller, and i need help finding adequate cells for the job. My biggest concern is cycle life, i'm willing to give up some performance but have a battery pack that will be reliable even after 750+ cycles.
For now my favourite is the Samsung INR18650-25R, with which i'm planing on building a 20s13p configuration with 150A cont. and 300A peak.

They seem to be good, but their cycle life is poor, at least to me: (72% of the original capacity for high drain application, thats 673Wh just gone)

I even looked at LiFePo4 cells, because of their long cycle life, but i'm not so sure how good they are for e-bike application.
https://bit.ly/2KLCDLb - The best i could find, but as everything from China i can't really trust them.
I've read mixed reviews, someone tested them at 15A cont and they got pretty toasty (75C), also their real capacity is ~5Ah.
A similar battery pack to the Li-ion one will be 8 killos more and much bigger, so i really don't think they are well fitted for this kind of application.
I'm open to any suggestions for good cells
