Frequently Asked Questions
Q: What type of welder is compatible with these 18650 nickel spot welding tabs?
A: These nickel plated steel tabs are designed for use with standard spot welders or pulse spot welders commonly used in battery pack assembly. They are compatible with most DIY and professional spot welding machines that support nickel strip welding on cylindrical 18650 cells.
Q: Are these tabs suitable for high-drain battery pack builds such as power tools or e-bikes?
A: Yes. The nickel plated steel construction provides the conductivity and mechanical strength needed for moderate to high-drain applications, including power tool battery packs, e-bike batteries, and portable power banks. For very high-current applications, ensure proper tab width and layering to meet your current requirements.
Q: What is the thickness and shape of each tab?
A: Each tab measures 2.5 × 1 cm and features a T-shaped profile optimized for 18650 cylindrical cell connections. The T-shape allows for a stable, well-aligned weld point during battery pack assembly.
