4PCS 18650 Battery Spot Welding Fixture Jig Clamp Set – PLA

4PCS 18650 Lithium Battery Spot Welding Fixture Jig Clamp Set

Build cleaner, more reliable battery packs with this professional-grade 18650 spot welding fixture set. Crafted from reinforced hard PLA, this 4-piece jig clamp assembly bracket holds cylindrical 18650 lithium batteries firmly in place, eliminating cell movement during spot welding so every weld lands exactly where it should. Whether you're assembling a DIY power bank, modifying an e-bike battery, or building a custom lithium pack, this fixture delivers the precision and repeatability you need.

Made in Mainland China.

Key Features

• Excellent Electrical Insulation: High-quality reinforced PLA is naturally non-conductive, effectively preventing accidental short circuits during the spot welding process and keeping both the operator and the batteries safe.
• Precision Positioning Slots: High-precision molded slots are sized to fit standard 18650 cylindrical lithium batteries perfectly, eliminating cell displacement during welding for neat, accurate, and reliable results every time.
• Long-Lasting Durability: Thickened, hardened PLA delivers strong impact resistance and structural rigidity, resisting deformation after repeated long-term use — outlasting standard plastic welding jigs.
• Lightweight & Easy to Handle: Low-density PLA keeps the entire jig set significantly lighter than metal equivalents, making it easy to carry between work sites and reducing hand fatigue during extended welding sessions.
• Scratch-Free Battery Protection: One-piece molded construction creates smooth, burr-free contact surfaces on all edges, protecting battery casings from scratches during fixing and operation.
