I hope I'm not taking too big of a leap here, I was gonna do a small boost pack on a hybrid, now I'm thinking 20+ kWh full EV conversion daily driver. I haven't even picked out a donor vehicle or electric drivetrain yet. In over my head a bit, I think.

There are several type of 18650. From the power type to the energy type.
For a boost pack you can chose energy one.
For a main pack power one are better, because amperage will be probably highter then temperature can be a problem, needing some ventilator at least, temp monitoring probably.
Just for help, two links:
Battery test-review 18650 comparator
AkkuDB
So you can compare with the one you are buying.
For comparaison, I bought more then 936 new LG cells 2.8Ah 2$ each+transport+taxes. Now they are at 2.2$.
