Looking at the photos, they have the horrible stamped steel with a hold punched through it for the ring terminal.

If copper conducts on a scale of 1 to 100, copper is 100 and steel is about 8, depends on its allow configuration.

I had employed such cables in the past. Had 2 4 awg cables in parallel on my ground from shunt to battery.

one 4 awg cable had these stamped steel ring terminals, one had tinned copper ring terminals

When I put my clampmeter over the wires individually, one was passing 3.5 amps the other 6.5.

When I lobbed off the steel ring terminals and crimped on copper ones they shared the load 50/50

These surplus center cables are likely Acceptable to good, , if one cuts off the steel ring terminals and crimps/ solders on a quality lug, which requires a new lug, which will be about 3$

One should also know SAE gauge cable is 6 to 12% thinner than AWG, with a corresponding loss in ampacity.

I make mine & have a wooden spool of #2 & 2/0 pure copper but it seemed cheap if someone was putting a system together. You can call as they've been helpful & knowedgable to me in the past.

another good source for cheap wire would be upullit,the positive battery cable on a chevy truck goes from the battery to the starter,maybe 6 feet and should be copper,thicker strands so not so flexible

I love surplus center, Done lots of business with them. Mostly fans.
All hail EBM Papst.

Just beware of steel ring terminals. they have lots of resistance when new, and they rust, and all mating surfaces then get worse and worse until..........
