Always order big!
I needed a minimum of 2 AWG wire to create interconnects between batteries in a large bank. If you note, these say 1/0 Gauge, not AWG. What is 1/0 Gauge? Who knows, it's fake. Meaningless, because it is not standardized so you have no clue what you are getting.
What did I get for my 1/0 Gauge wire? Something that was in between 1 and 2 AWG (closer to 1). This was perfect for my needs because I knew darn well how big to order when they say gauge instead of AWG.
As a rule of thumb: If they as gauge, order 3 - 4 sizes larger than you need in AWG. This will always net you larger wire than you need but I have never had it net me wire smaller than I needed.
At the price I got it for during prime days, it was a steal for 2 AWG wire, so I win!
I hope you found this helpful!

Heavy duty and has lasted three years so far
I have had this relay installed in the engine bay of my Lexus RX 300, functioning to link the front battery to the additional battery in the trunk whenever the ignition is on. The relay has worked reliably for about three years now with no complaints besides one minor comment, be careful when threading down the nut on the Low voltage side. It is prone to stripping
