12V DIY Portable Spot Welding Machine Cell Storage PCB

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

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: 19 * 10 * 3cm / 7.5 * 3.9 * 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 2.5 sup2; or 4 sup2; wire, then it will reduce the risk of power tube burnt.
