DIY 12V Spot Welding Machine Battery Storage PCB Circuit Board Spot Welding Machine Welder Equipment Accessory For 18650/26650

TYPE 1

This product is very useful in daily life, with an battery, it will become an energy storage spot welding machine for welding nickel pieces such as lithium batteries and nickel-chromium batteries practical, easy to operate and use, wide application range, has a long service life. Come on and try it. ​ ​Features: ​There is a window on the back of the drive part, you can add copper or tin by yourself. ​The external pads for the LED and the on-board buttons are added to facilitate the connection of the LEDs and buttons on the board to other places. ​The upper and lower MOS design is bold and tinned to make the internal resistance smaller and the current stronger. ​Using 25V low internal resistance and high frequency capacitors makes the power supplies more stable. ​This circuit with a 12-V battery will become an energy storage spot welding machine for welding nickel pieces such as lithium batteries and nickel-chromium batteries. According to different configurations, the thickness can be about 0.1mm-0.15mm ​ ​Specifications: ​Material: PCB ​Suitable for: 18650/26650/32650 lipo battery ​System voltage: 12-V-14.6V ​Working current: 90-150A ​Suggested battery: (not included) ​20-45ah Lead-acid battery with fine performance and small internal resistance ​3.5-5.5ah 45C 3S aeromodel lithium battery pack ​30-35ah capacity 18650 battery pack ​Package size: 190 * 110 * 30mm / 7.5 * 4.3 * 1.2in ​Package weight: 110g / 3.9ounce ​ ​Note: ​If the battery is pretty  and the internal resistance is very low, and then there may be large current overload. ​If you are not sure about your battery, it's better to extend the wire by around 1 meter with 2.5² or 4² wire, then it will reduce the risk of power tube burnt. ​ ​Packing list: ​1 * Main Circuit Board ​2 * Input Wire ​2 * Output Wire(with Welding Pen) ​1 * Welding-Components Kit
