DIY Reliable 18650 Battery Spot Welder, Simple and Low Cost (only two main parts,Wifi - RustyOx - 06-06-2021
The video introduces a simple and reliable 18650 battery spot welding machine. The spot welding machine consists of only two main components of the ESP8266 control board and high-current relay, with WIFI interface， parameters can be adjusted through the web page. It is very suitable for DIY. I made this spot welder after trying the midi DIY MOSFET spot welder I bought and the super capacitor spot welder I made, and successfully used it to rebuild my electric bicycle battery.
