Hi Cl,

These are links to components (or similar) which I suggested earlier. 
Sometimes a picture is worth 1000 words.

Note the ring terminals are long-barrel, brazed-seam, non-insulated.  By 
long barrel you have longer crimp region, stronger, lower resistance. 
Long means about 5 to 7 times the diameter of the wire.
There is a seam/joint in the barrel.  You want welded/brazed seam. 
Avoid ones with open crack in barrel.
The non-insulated ring terminals are to be preferred, because you can 
perform a better, more agressive type crimp.  This is kind of like the 
difference between biting with teeth, and biting with no teeth.
