What diameter copper wire (single core, not isolated, open air) is needed to safely conduct 120A current from 22.2V battery to a load on 30cm distance?
Of course I searched on the Internet and there is way too much information. Different sources state different things, which is not obvious for me. If for someone it is obvious, please explain here. Some resources state 5x difference.
25C ambient temperature, drop is not critical, but less is better.
