Dead laptop and power tool battery packs usually have at least some useable 18650 cells in them. A friend has built more than one battery pack for electric scooter out of harvested cells.
You do have to know what you're doing when working with unprotected cells though.
- lorenzhs 8y agoYes it's easy enough to get unprotected cells, but the hoverboard batteries usually have short circuit and undervoltage protection, both of which are very nice to have as a beginner. If you know what you are doing you can also get RC hobby batteries for not too much money.
