[RE-wrenches] Large ferrules

Friends:

More inverters these days present lugs for battery connections instead of
studs. I bought some 2/0 and 4/0 ferrules to accommodate the fine stranded
MTW we use. I have a cheap hex crimper but the results are poor with a
sharp “wing” on either side of the crimp.

What does the hive mind suggest for a ferrule and crimper for these larger
wire sizes?

Thanks in advance.
