@tipsbattery: lithium-polymer (Li-Po) battery being cut open with a utility knife. I don't recommend opening or cutting this type of battery. If punctured, it can: Catch fire or smoke. Release harmful chemicals. Become very hot and cause burns. If your goal is to make a YouTube or TikTok video, you can safely show the battery without cutting it open and explain its parts instead: Outer pouch Positive (+) wire Negative (−) wire Protection circuit (if present)
