21700 Battery cell with High-Capacity

[Easy_Rider]

I would like to make some new experiments with 21700 batteries. I´d like to have at least 20Ah in 36V (10S).

Found the 50E at nkon.nl here: https://www.nkon.nl/samsung-inr21700-50e.html

Found a new battery from LG Chem at enerprof.de: https://enerprof.de/shop/batteries/li-ion-batterie-cells/samsung-sdi-inr21700-30t-21700-3000-mah-35a-copy-copy/

What do you think? Which one should I take?

Yours

It is hard to comment without knowing what you expect from the pack,..but both of those cells are only 8-10 amp max output, so you will need to work with that limitation.
I doubt there is much data or experience with either cell to make comparasons.
There are other 5Ah cells with higher output capability.

The cheaper and a higher C rating 50E is a no-brainer

I´d like to assemble a 10S4P with 21700. It saves me 2 parallels in comparison to 18650. I am aware, that the 21700 have lower C rate in this capacity, but on 250 Watt motor, I don´t see any problem.

I was just wondering if any one around here gained any experience on those types of batteries?!

Second I´d like to know, if any one knows enerprof.de as supplier of batteries? the LG 21700 you can get in Europe so far only from this shop in Germany. Nkon is well-known around here...
