What welding rods are used to connect the battery pack
With the kWeld, there is no type of battery that you cannot build. For those that don''t have the funds for a kWeld, the Arduino Battery Spot Welder provides a viable alternative. If you have the space for a large-format welder and don''t need to do any copper welding, then the SUNKKO 737G+ or Mophorn 709A spot welders will do just fine.
