Black 1 Foot 4 AWG Battery Cable, Negative Only 3/8" M10 Made in USA

This Spartan cable is of very good quality. Their cables are all copper (not copper clad aluminum). Their car battery clamps have a copper strap between the jaws. Never seen this before at this price. My order arrived four days early. I will be buying all my needed cables through this company.

Unsure why my Honda stated that these were the right fit. They arent. Quite thick and much larger connectors than what I need. But seem to be of high quality.

Very well-made. A quality product and made in the USA!

Bought this cable to hook up the starter on my outboard motor to the solenoid. One minor issue is the lugs were crimped 90 degrees out from each other. That made installation annoying due to the cable thickness but doable. They need better quality control during lug installation.

Monster of a cable, way overkill for what I needed it for but I wanted maximum power to my fuse box and it really delivered. I have a high amp alternator so I’ve had to modify the wiring to get any true benefit. Yes, it’s a bit hard to work with, given the weight of such an heavy gauge and especially the lugs which are huge! Great quality!

Awesome power just what I needed. Very pleased.

They don't sell what I needed, Anderson 175a+1/0+5/16 lug, so I bought what they had and hacked em up. I also wanted an Anderson 120a to Anderson 175a so made that as well. @Spartan Power, please consider making these available.
