E-longboard battery pack from laptop 18650 batteries

[Day1]

Hi all,
This is my first post so please be understanding ,
Some time ago I started to salvage 18650 batteries from dead/used laptop battery packs,

I have ended up with:
ICR18650 26C - 33pcs
ICR18650 26F - 12pcs
UR18650FM - 44pcs
ICR18650 22F - 14pcs
LGABC21865 - 16pcs
SE US18650GR - 24pcs
Capacities are ranging from 2000-2500 mAh all of them are tested(internal resistance, voltage drop over time and heat output while charging/discharging).
I know that batteries mentioned above are ''ICR" chemistry (LiCoO2) and they are not designed to withstand high current draw but would it be possible to run SK3 6473 192KV /VESC with them (76-80mm wheels with 16/36 ratio )?
I am thinking to make 12S4P pack to lower A draw by giving higher voltage but that means that most likely I will have to mix batteries....
Is it ok or I am begging for trouble?
Thanks!

Do you know how many amps you will draw at 12s? I think 4p would be to small, but with a longboard you dont have very much space of course... I did not find info on your motor, only the 149KV one, and that was max 2250 W. If you are gonna feed your motor 2 kW, you need more than 12s4p laptop cells!

No, and that's the problem,if this setup would not take more than 20A with 12s (740W) than I should be good as max amp draw from single cell is 5,0-5,2A (20A in total for 4p pack)
You think that I will ever put out more than 1000W? I think those 2750W (sk3 6374 192kv) is only max value that motor can withstand.
It would be interesting to know what's the avg. and peak Amp draw for similar set up.

5A from a used laptop cell is probably too much. And I see the motor does not want more than 44V? Your 12s pack would be 50,4V when fully charged.
I have no experience with these motors so I dont know what the power output will be, but I guess that is up to your ESC?

Ok, than laptop 18650 cells are no go,

What about RC lipos? 3x4s lipo packs (to get 12s)?

Is there any advantage in using 18650 high amp discharge calls?
