6 FAQs about [How to disassemble a 20v lithium battery pack]

How do you disassemble a lithium-ion battery pack?

Can you take apart a lithium-ion battery pack?

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.

How do you remove a battery pack from a case?

There’s no real trick to removing the battery pack from the bottom part of the case. It just pulls out. However, it’s in there very tightly. Start with one end, pry (carefully - don’t short the pack out), and it comes out. The wire between the battery pack and the output terminals is quite substantial, and is secured with an awful lot of solder.

How do I fix a bad 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.

What happens if a battery pack dies?

Remember, battery packs are made of many cells that are grouped in a specific way. So, if one cell dies, it will bring down the cells that it is immediately attached to. This is bad news for the cells in that group but it's good news for the rest of the battery pack. It generally means that the other cell groups are just fine.

What does it mean if a lithium ion battery pack is split?

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.
