Why are you shouting??? CAPS LOCK, MAN!!! Yes, the power cable you have is acceptable. As a better solution, a #2 from the battery, with a fused distribution block for the amps might work better for you. The number 2 should be fused at the battery for 225A, and you will have fuses rated NO HIGHER than 150A in the distro block. This might help with your voltage drop issue.

It all reminds me of something that Molière once said to Guy de Maupassant at a café in Vienna: "That's nice. You should write it down."
