solid product, but preperation needs work
This is some solid good 1/0 gauge OFC for your power needs. A few things I was not impressed about was the pre crimped ring terminals where installed on the wire poorly. Don’t get me wrong it was not going to fall of or fail, but it looked like someone did it with their eyes crossed. Along with that a few extra heat shrinks would have been nice. This did not deter from ordering more products from SHCA as I have already ordered more, but it would be nice if they would fix the few problems I talked about.
