Precision 18650 Spot Welding Jig (3S to 10S) Series
“Free model certificate for commercial use, Just give a credit to FortuneAU”
Upgrade your battery building experience with this professional, low-profile welding jig. Designed to make DIY battery assembly faster, safer, and much more pleasant.
Why use this jig?
- Scalable Design: Supports single-row packs from 3S all the way to 10S.
- 8mm Nickel Ready: Specifically optimized for 8mm wide nickel strips to ensure perfectly centered, straight welds every time.
- Material Efficient: I've reduced the height to the absolute functional minimum. This saves filament and cuts down printing time while maintaining rock-solid cell stability.
- Professional Look: Keeps your cells perfectly aligned for a clean, factory-quality finish on every pack.
- Universal Use: Designed to work comfortably with any spot welder, whether it's a desktop unit or a handheld portable device.
- Safety First: Securely locks cells in place to prevent rolling, shifting, or accidental shorts during the welding process.
