I cut a cross-section of my battery cable crimps and it essentially is one solid block of copper:
See this page: https://sites.google.com/site/marksrvmods/home/battery-wiring Note that expensive crimpers are "calibrated". They make one or more connections on sacrificial wiring and cross-section them to verify that the crimps are good. Since I cheaped out on a crimper, I did the same to give me some confidence it was done right. A better crimper with the correct sized dies would not require the careful multiple crimps I had to do with this wiring. I've used the Powerwerx crimping tools on many 15, 30, 45 and 75A Powerpoles and not had any issues with them. I don't solder them. 73, Mark W7MLG ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to arch...@mail-archive.com
