I Found $200 in Batteries Using These 5 Gadgets
I cracked open an AI gimbal, a rechargeable work light, a portable car wash gun, and old laptop packs to pull the 18650 cells inside. I show how I test them, what voltage to look for, and which ones are worth keeping.
⚠️ Safety note: lithium cells can vent or catch fire if punctured or injected. Do this only with proper tools and protection.
