Yes; given the little data in the first post, the presumption was that since you didn't previously link to the video, that the cell company you linked was the source of the video and the cells you were discussing.
If not, you would need to ask the maker of the video where they got those cells and/or housings, if they didn't include that information in the video or somewhere else on the page the video is located. (I haven't watched the video as I don't generally have time to wait for someone to tell me things in a video, vs me simply scanning a page or searching a site for specific info, etc which usually takes a few seconds instead of who-knows-how-long (if they even ever get around to it :lol: ).
(and then in that case, the housings/etc have (presumably) nothing to do with the company you're asking the question about, which is confusing....)
I didn't cover any of the other points in the first post yet because the answers depend on the cells / housings / etc. that you want to use, among other things.
BTW, if the cells each have their own compression housings, the pack is going to be a LOT larger than it would if the compression was done for the pack as a whole. Up to at least several times larger, depending on the kind of compression the specific cells used require, and the size of the compression housings required for that.
