Don't Throw it away! Salvaging 18650 Lithium Cells from a Dead Battery Pack.

In this video, I carefully disassemble the pack, remove the spot-welded nickel strips, and test each recovered cell for internal resistance and overall health using a battery analyzer. You might be surprised how many cells are still perfectly usable even when the BMS fails. ⚠️ Safety Notice: Lithium-ion (Li-ion) and LiPo cells store high energy and can catch fire or explode if shorted, punctured, overcharged, or improperly handled. This video is for educational purposes only. Attempt battery disassembly at your own risk and only with proper knowledge and safety precautions. Stay tuned for the next project using these recovered cells.
