🔋 DIY 12V Portable Soldering Iron Battery Pack from Recycled Vape Cells 🔧
In this video, I’ll show you how I built a compact 12V lithium battery pack for my portable soldering irons (TS100 & SH72) using salvaged vape batteries and a few other repurposed parts. This is a great project if you love recycling, working off-grid, or just want a compact and rechargeable solution for your tools.
💥 I harvested 15 used 400mAh cells from vape pens and configured them in a 3S5P setup, giving me around 2000mAh at 12V—plenty of power for field soldering jobs. I also added a volt-amp meter for real-time monitoring, all housed inside a modified AA battery case.
✅ What You’ll Learn in This Video:
How to build a lithium battery pack from vape cells
Why cell balancing is crucial before wiring in series
Using TP4056 modules for safe charging
Monitoring power usage with a volt-amp meter
Building a DIY soldering setup for mobile use
🧰 Parts & Tools Used:
15x 400mAh lithium cells from vape pens
3D printed voltmeter case (model from Printables)
TP4056 lithium charging modules
DIY spot welder / soldering iron
Volt-amp display module
Recycled AA battery pack housing
🧪 The final result: a portable, high-current, and compact 12V power source for soldering irons, with power monitoring and modular charging.
