Building a 2S2P 18650 Battery Pack Using Spot Welding 🔋⚡

Описание: In this video I build a DIY 2S2P 18650 lithium battery pack using spot welding.
The pack uses two cells in series and two in parallel to increase voltage and capacity. I show the process of preparing the cells, welding nickel strips, and assembling the final battery pack.
This type of battery configuration is commonly used in DIY electronics projects, portable devices, and power systems.
