Home Depot has some nice lugs to chose from but you'd need a large crimper. There not really automotive lugs but they'll work. I bend them, drill a larger hole in them, brazed wire to them an shrink wrap them.
Well I bent my own lug, the straight part of the angle isn't long enough. Anyone know of a good variety source?
I bent my own, but 3/8 copper pipe might work. Smash one end closed, drill a hole large enough to fit over the stud and solder the battery cable into the open end.
