I need to acquire a good sized sealed lead-acid battery (12V car battery) in order to use the new KaeptnBalu Arduino based battery tab welder.
However, the battery leads that came with the welder have relatively small openings to attach them to the terminals on a normal car battery. In KaeptnBalu's video of how he builds the welder, I noticed that he had adapters on his battery terminals which allowed the use of the smaller openings of his welding tips. I did a quick look on Amazon and saw what I think are the exact same adapters!
They are extremely inexpensive and ship for free!
