all my life ive used 2x banana connectors. learned the hard way that only the best and best maintained were ok. even then they will surprise me with ir drop, warm up.
i admit i did not always use the best.
i just got some xt 90 conn from the xt 30,60,90 family.
not yet tested but they look and feel really good,AND cannot be "pib", put in backwards,an easy flub with banana conn.
lots of rework to do as i made some very nice dc panels from b conn and quite a few of them, many gold...
off topic, i see icom fuse conn are much tighter than others and especially "hamfest specials" icom uses a good quality "faston" conn, very tight.
ive had hamfest conn get hot in use, drop a volt+...
note xt 30,60,90 is amp rating...
