An adapter cable to power the Spot Welder with a Lipo battery that has a XT90 connector. You can use for example this Lipo: Turnigy nano-tech 5000mah 3S 65~130C
- about 10cm long 8AWG cable
- XT90 male connector (black)
- 2x cable shoes for M6 screws
Mounting Options:
You can use the adapter with or without the cases on the Spot Welder. When using without the cases make sure you insulate the connection on the positive welding cable with some electrical tape.

Been using it to build 2 batteries now. Paired with a good lithium battery like the turnigy 130c recommended, welds are very good.
Arduino fried spontaneously once. Not sure what happened. However, the source code is available and I was able to upload the code to a replacement Arduino nano. Back in action.
Overall, a very good battery powered spot welder. Thank god for open sourced code and open sourced arduino. So there is some degree of repairability.
