Spot Welder for Battery Pack Assembly | Battery Spot Welding Machines & Equipment
A Spot Welder is an essential machine for assembling lithium battery packs by welding pure nickel strips or nickel-plated steel strips to cylindrical battery cells such as 18650, 21700, 26650, 32700, and 33140. Spot welding creates a strong electrical connection without applying excessive heat directly to the battery cell.
Lion Battery supplies battery spot welding machines, spot welding accessories, and battery pack assembly equipment for lithium battery manufacturers, EV companies, battery repair centers, educational institutes, research laboratories, and DIY battery builders.
What is a Battery Spot Welder?
A battery spot welder uses a high-current, short-duration electrical pulse to join a nickel strip to the battery terminal. This process minimizes heat transfer to the cell compared with conventional soldering and is the preferred method for most cylindrical lithium battery pack assembly.

Frequently Asked Questions (FAQ)
Why is spot welding preferred over soldering for lithium battery packs?
Spot welding joins the nickel strip to the battery terminal using a short, high-current pulse, reducing heat transfer to the battery cell compared with direct soldering. This helps protect the cell when performed correctly.
Can I weld pure nickel strips?
Yes. Most battery spot welders are designed to weld pure nickel strips within the thickness range specified by the machine manufacturer.
Which battery cells can be spot welded?
Spot welders are commonly used with 18650, 21700, 26650, 32700, and 33140 cylindrical lithium battery cells.
Do you supply spot welding machines for battery manufacturers?
Yes. Lion Battery supplies battery spot welding equipment and accessories for battery manufacturers, repair centers, training institutes, and industrial users.
Do you provide battery pack assembly training?
Yes. We also provide Battery Pack Assembly Training, including spot welding techniques, BMS installation, battery testing, and battery pack design.
