Description
⚡ *Never struggle with custom battery packs again!* In this video, I'll show you how to build a DIY battery spot welder, perfect for assembling your own custom battery packs. Learn the process from circuit design to testing, covering essential techniques like spot welding. This resistance welder is ideal for working with 18650 cells and other lithium batteries.
*What You Will Learn in This Video:*
1️⃣ High-current MOSFET parallel configuration.
2️⃣ NE555 pulse timing circuit design.
3️⃣ The process of ordering professional PCBs from JLCPCB.
4️⃣ Battery pack assembly with spot welding.
5️⃣ Safety systems for power electronics.
