Re: Battery cable video. What do you think?
rosin core.
biggest diameter wire with the highest number of strands. be carefull simply eyeballing guage based on insulation diameter.
cheap wire has thick insulation made from material that is soft and even feels cheap
welding wire is usually best. FAA-PMA approved is better still but maybe overkill.
bigger core diameter made up of many more strands of finer copper wire.
terminals are tin coated brass. but be careful as tin melts at only a slightly higher temperture than the lead soder.
you may notice in his video that while its hot enough to melt the lead and even melt the insulation, the mass of the terminal draws away heat befor it can bond the cable to the terminal. Thats why it pulled apart with such minimal effort.
and heat shrink should be used to reduce the corrosive effects of acid fumes at the connection between the terminal end and the copper cable. this is important because in that envirionment, with acid fumes so close by, dissimilar metal corrosion is always a consideration
