Yes! When a battery pack 'goes bad' it's usually because the BMS has decided to shut it off for one of many reasons. This is why it’s a good idea to disassemble lithium-ion battery packs for its cells. In most other cases, just a single cell has failed. Remember, battery packs are made of many cells that are grouped in a specific.

In the battery you are trying to disassemble, notice the continuous sheets of nickel - as you probably know, these connect the negative of one cell to the positive of the next. What I would do, is put the tip of the pliers under the spot welds and push down on the pliers so the tips are pushing the nickel strip away from the cell, much like

It's important to be slow and methodical when removing the nickel strip from the cells. It's helpful to grab a small bit of the nickel with a pair of pliers and then pull the nickel off with a twisting motion. Be very careful!
Taking apart a lithium-ion battery pack may appear challenging at first, but with a solid approach and some patience, anyone can do it. It’s super important to understand the connections between battery cells and to recognize the potential risks, like shoulder shorts.
The nickel strip on the battery packs I have is approx 0.3mm thick and is nickel-coated steel strip. It is welded 4 times per cell per side (2 weld operations, 4 indents from the spot welding pins). The diameter of the indents is approximately 1mm or perhaps 0.8mm. My current approach: The pliers look like these:
It generally means that the other cell groups are just fine. Lithium-ion battery packs are spot welded together. So it's no small feat to separate the cells. In fact, breaking down a lithium-ion battery pack is a rather involved process that takes care and patience. You have to be extremely careful when breaking down a lithium-ion battery pack.
First, you need to figure out what's wrong with the pack—either bad cells or a wonky Battery Management System (BMS). If it's the BMS, just swap it out with a new one. The BMS keeps an eye on the battery pack's performance and makes sure everything's working within safe limits. Replace the bad BMS, and your battery pack should be good to go.
