I recently completed my 560AH 12V battery (2P4S) using 8x Eve 280AH cells (purchased through Alex at Basen) and 300A Chargery BMS8T and 300A DCC. You can see it installed in my electrical compartment of my 2020 Ford Transit van conversion. After top balancing to 3.64V, and then leaving sitting in parallel for 2 days all 8 cells measured 3.616 V.
Box is built out of 5/8" baltic birch plywood, 5x 3/8" thread rod (cut to same lengths and all tightened/compressed evenly), and ~3/8" plexiglass. I replaced the cell factory screws with studs, lockwashers, and nuts - and did not use loctite when installing.
Thanks to everyone who has posted ideas around this topic and answered questions in the past. I've calibrated the BMS and look forward to running more tests. Let me know if you have any questions or feedback.
