I know, don't worry
I just thought I could share an other method which would work in both situations, could be useful to other people than the OP reading this thread
Anyway sorry if this was off topic.
I know aerogel, it is indeed some fine piece of insulating material. But the one you're pointing me at wouldn't work at all, reason being it is way too brittle. Aerogel is nice for static loads, it can support hundreds if not thousands of times its own weight, but it would be crushed in no time with a 10-20 kilos battery moving around with all the vibrations of a moving vehicle, it doesn't hold very well if the load is dynamic.LockH wrote: ↑Jan 25 2019 4:05amRe Aerogel... supplier:

Yeah, maybe "pricey"... but one nice thing about "small EVs"... the parts/components are also small.
But since you insisted on this matter, I made a bit more research and it turns out that they are now making some aerogel sheets, very similar with the fiberglass whool you can find in home insulation.
This stuff is not as expensive as I would have expected, at least here in China, about 25 bucks for 1 square meter:

It should work better than the polyurethane I expected to use so I might give it a try, thanks for the idea!
