I currently have 2/0 running between my agm under the hood to my rear agm and superbank.. Im moving my batteries in the rear and need to gain some length in the 2/0 to make it happen.. I could run my 2/0 directly to to my 300amp alternator and gain the wire i need for the rear.. Is there any draw back to going straight to the alternator? I have 2/0 big 3 under the hood also. Thanks.
