How to separate these LiFePO4 pouch cells?

[tmho]

I got a 6s2p LiFePO4 battery pack from a friend. I have no experience in this kind of pouch cells. I want to separate them so that I can rearrange them for other purposes. What is the easiest and safe way to do so?

In my experience, large format pouch cells like that are often joined with adhesive, and there’s no way to separate them without damaging them.

You can cut the cell tabs apart and use wire jumpers to put them in an electrically different arrangement.
