Made my own lugs using soft copper tubing, much more robust than any premade lugs that I have looked at.
Select soft copper tubing size that just fits over the wire.
Then crimp the tubing (I made an adapter from a piece of steel pipe sized just large enough for the tubing to slide in then used a vice to hold the steel pipe in place).
Then solder (hint, heat the copper pipe, not the wire, then test to see if hot enough to melt the solder by touching the solder to the edge of the copper pipe).
Then flatten the lug end and drill hole(s).
Trim lug length and connect.
Cost me not even a penny to make the ends for ALL of my battery connections and much heavier than what you can by. Tried this on my 250A stick welder when I needed to extend the leads. When to buy welder cable and lugs and realized those lugs were so skimpy that I could make my own and make them better and cheaper.
