Re: (ET) battery cables



I thought people didn't solder heavy current cables because the solder
will melt out and run into other stuff if the connection overheats?

If I have my home foundry up and running by the time I need a new set
of cables, I'll see if I can lost-wax cast solid copper ends onto 4
gauge, and sidestep the whole solder vs crimp issue altogether.
