Well, I've been soldering all my connections like
Why the damn greedy manufactures would not make a crimp tool like this with large hole?
It would be possible to fit any connection and crimp it, hex version is way better then a square shown here.
Now the cable lugs and connectors does not fit through the hole ! And even if one gets proper crimp tool then it's even harder to get proper wire size and connectors. The insulated are color coded, but I would never trust these, and non insulated are like very many types with their own die set. Nonsense I say, when there are hex crimp tools like above and soldering afterwards if one prefers it.
