You can, but foam is for jarring and bouncing, it’s not good at protecting against abrasion like fishpaper, so definitely have fishpaper and shrinkwrap under that, don’t use that on the cells alone
Every battery is custom so I can’t tell you how to build yours but mine frequently look like
p-pack of cells: juice comes from here
fishpaper: abrasion/vibration resistance
shrinkwrap: mostly ingress protection and appearance
foam: protects against physical shock

Sorry, how could I forget to show you the battery. Acido has built it for me! It’s already… Done with blue heatshrink and stuff. Why is it always blue though???
Will it be fine just reusing the foam stuff from the enclosure to give it a comortable, safe zone?
1: would directfets offer better performance than the stock FETs? Yes.
2: Would they fit? No. Unfortunately the outline/footprint/connections/everything of d2pak fets are totally different than directfets, so you’d need to redesign the board to fit the new fets.
And if you’re going to go to that much trouble, you might as well implement some other improvements… etc etc until you land on the vesc6 designs.
It’s vaguely possible that you could make some kind of “adapter PCB” that would have directFET pads on one side and d2pak pads on the other, and some nice high-current vias/traces in between to make that magic happen… But I don’t think they exist yet and I ain’t gonna design them unless there’s $ involved. Too many projects already.
Stretching helps. Get a scissor or something under the heat shrink and stretch it. The fact that i don’t see any heat shrink i assume you removed it all together
I think we’ve all had that moment of “Holy shit I’m a genius! Just do X to Y, it’s so simple!” … time goes by, thinking happens … “Wow, that was a dumb idea. Of course X doesn’t fit into Y.”
