Please review my buy list for lithium build

[somfas]

I just purchased 10 Leaf modules for a 72v conversion. I have been in touch with Ian to purchase a Zeva BMS. I plan to purchase:

1) EVM53 which should work (2x12 cell)??
2) Optionally some kind of CAN current sensor (no clue, but would like it to be done right)
3) 72V-12V step down converter (will take out my 12v accessory battery)
4) Optional EVMS Monitor
5) TC Charger (HK-H-H99-25 recommended but sold out from Aliexpress)

Assuming I can figure a way to assemble to batteries and for a collective batter pack, is there any other items I would need in addition to whats mentioned above? Thoughts on using plywood or metal for end plates to sandwich the plates together? How tight should I squeeze them?

Thanks!
