    Product Description

    This portable 12V battery spot welder PCB kit is a compact energy-storage welding solution designed for DIY lithium battery pack assembly and repair. When connected to a suitable 12V power source, the board functions as a high-current spot welding machine capable of welding nickel strips onto lithium battery cells.

    The design features reinforced MOSFET paths, low-resistance capacitors, and flexible external connection pads, providing stable output and strong welding performance for hobbyists, technicians, and battery builders.

    Key Features

    • Designed for DIY battery spot welding

    • Compatible with 18650, 26650, and 32650 lithium cells

    • Operates on 12V–14.6V DC power

    • High-current output suitable for nickel strip welding

    • Reinforced upper and lower MOSFET design to reduce internal resistance

    • External pads for LED indicators and control buttons

    • Rear drive-section window allows adding copper or tin to enhance current flow

    • Uses 25V low-resistance, high-frequency capacitors for stable power delivery

    • Self-triggering welding operation

    Technical Specifications

    • Material: PCB

    • System Voltage: 12V – 14.6V

    • Working Current: 90A – 150A

    • Weldable Nickel Thickness: Approx. 0.1mm – 0.15mm

    • Supported Battery Types:

      • 18650 / 26650 / 32650 lithium cells

    • Recommended Power Sources (Not Included):

      • 20–45Ah lead-acid battery with low internal resistance

      • 3.5–5.5Ah 45C 3S lithium model battery

      • 30–35Ah 18650 battery pack

    • Package Dimensions: 190 × 110 × 30 mm

    • Package Weight: 110 g

    Usage Notes

    If the discharge capability of the power source is uncertain, it is recommended to extend the input cable by approximately 1 meter using 2.5 mm² or 4 mm² wire. This helps reduce overheating risk and protects the connector terminals.

    This device is intended for spot welding nickel or nickel-plated strips only and is not designed for traditional soldering.

    Applications

    • DIY lithium battery pack assembly

    • Repair of 18650, 26650, and 32650 battery packs

    • Spot welding nickel and nickel-chromium strips

    • Maker and electronics hobby projects

    • Battery prototyping and research

    Package Includes

    • 1 × Spot Welder Main Circuit Board

    • 2 × Input Power Wires

    • 2 × Output Welding Wires with Welding Pins

    • 1 × Welding Component Kit

    Why Choose This Spot Welder

    This 12V portable battery spot welder PCB kit offers a compact, powerful, and customizable solution for battery welding applications. With strong current output, stable power design, and compatibility with common lithium cell sizes, it is an excellent tool for DIY battery builders and technicians.
