The battery builders club

Working on a project I thought up.
I wanted a way to travel on an airplane with my board.
I also wanted a 12s4p from molicel p42a.
I came up with this…
4p glued together using 21700 nese hardware.
Direct solder balance wires and series connections to tabs. Use 10awg to connect series allowing flexibility between P groups.
Planning on using black RTV to secure the nese hardware to the enclosure.
I am planning on using a friction fit for the cells to stay in place. Then closed cell foam on top of cells to take up the rest of the space in the enclosure so they have no where to go… roast away…
