Following a video update from automotive engineers Munro & Associates showing that opening the 4680 battery cell on the Tesla Model Y was “harder than they thought,” and a few other videos depicting attempts to open the cells, the team has finally won.

After two other attempted videos on the subject, Munro & Associates have finally gotten beneath the pink foam included in the Tesla Model Y unit with 4680 batteries in the most recent video shared.

“What we have found out so far is that taking this apart is a miserable deal,” says Munro of the long-anticipated process. “I cannot begin to tell you how many hours we’ve sunk in on this thing trying to get things to pieces.”

The team had to rent a dry ice blaster to remove the pink foam on one edge of the structural pack, revealing a multi-layered metal atop the cells themselves, with aluminum on the bottom and steel on the top.

Steuben notes that there is a plastic ABS base beneath the actual 4680 cells, as well as a thin layer of mica for the purpose of external venting.
