Is there a US vendor that sells this large shrink wrap, not for cells, but big for the whole pack? Similar to these guys below.

I am having to tear down an ebay lifep04 48V pack b/c it seems they put the wrong BMS in it, it's cutting off at 45V not ~38V and I'm only getting about 1/2 the stated pack capacity. So I'm planning to tear into it, confirm that is the issue, replace the BMS if needed, and re-wrap it.

Thanks!
