Frequently Asked Questions
Q: What type of welder do I need to use these 18650 nickel spot welding tabs?
A: These nickel plated steel strips are designed for use with a standard handheld spot welder or pulse spot welding machine. A spot welder with adjustable power settings is recommended to achieve clean, strong welds on 18650 lithium cells without damaging them.
Q: Are these nickel strips compatible with battery types other than 18650 cells?
A: Yes! While optimized for 18650 configurations, these T-shaped nickel foil tabs are also widely used with nickel-metal hydride (NiMH) batteries, polymer lithium batteries, and general power battery packs used in power tools, instrumentation, and specialty electronics.
Q: What are the dimensions of each nickel strip in this 50-piece pack?
A: Each individual strip measures 2.5 × 1 cm, providing a consistent, repeatable size for professional-quality battery pack assembly. The T-shaped design ensures proper alignment across standard 18650 cell terminals.
Q: How many strips are included, and is this sufficient for a full battery pack build?
A: Each batch includes 50 nickel plated steel strips. The number of strips needed depends on your battery pack design — for example, a 10-cell series pack typically requires at least 10–20 connection tabs. Having 50 on hand gives you plenty for a mid-sized build plus spares for practice welds.
