🔋 DIY 3.7V Lithium Battery Charging Circuit Using Light Bulb 💡
In this video, learn how to safely charge a 3.7V lithium-ion battery (18650) using a 5V 1A mobile phone charger. Instead of using a traditional charging module, we cleverly use a small incandescent bulb as a current limiter to protect the battery and avoid overcurrent.

This trick is simple, effective, and ideal for beginners who want to learn battery charging basics without complex circuitry!

⚙️ What You'll Need:
✔ 5V 1A Mobile Charger (USB type or adapter)
✔ 3.7V 18650 Lithium Battery (MaxPower or similar)
✔ Small Incandescent Bulb (used as current limiter)
✔ Basic connecting wires

🧠 What You’ll Learn:
✔ How to charge 3.7V lithium-ion battery using a 5V charger
✔ Using a bulb as a current-limiting resistor
✔ Simple battery protection without BMS
✔ DIY charging circuit without special components
✔ Safe trick for slow charging lithium cells
