How big of a charger do I need?
"melting sold onto the bare copper.
Than flux again and inside the lug. Crimp it on and solder it full."
Marine cable for use on a boat will be tinned , not bare, so will the terminal end..
It takes huge heat to get a #4 cable as a starter would have , so with a torch the insulation has a hard life.
After being tinned the cable is SOLID and as easy to crimp as a copper bolt.
Crimp, and dunk is the least hassle , and does the best job.
