I always found the hexagonal crimpers to not work well with the thinner
lugs that we usually use for batteries. The hex crimpers are good for
the UL listed heavy wall lugs however. I have a couple of different
crimpers that work like the one below: indent on one side and V on the
other. That type works well for thinner wall lugs. I have had a
Greenlee model, and currently have a chinese one that is fine, its
similar to this:

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.
