I have this 270 cell battery I’m making (again) and am worried the crazy glue and welds aren’t strong enough and maybe if I drop the motorcycle cells could come detach or short. I’d like to add an expanding foam that was light and had decent rebound so it doesn’t collapse.
Polyurethane comes in all types of hardness but I fear it will not bend and rebound with physical stress and instead break or collapse.
Silicone expanding foam I can only find in 25a duro or maybe 40a if I want to spend a lot. I think neither is hard enough but it’s flexible and won’t break.
There’s fish paper between cell groups as well as vinyl wrap with plastic o-rings and I’ll add another paper o-ring before I weld it.
What you recommend? I don’t want to glue it to the box so can get it out if need to.
