battery relocation question


Recommended Posts

The starter will pull what it needs, if your wire can't support that current them you'll get voltage drop.

With your only battery in the trunk, you'll want your cable runs large.

I have 0ga in mine and I still drop to 10v when starting since the starter pulls so much current.

When first cranking, your starter motor coil acts like a dead short on the battery until the coil saturates. Not a whole lot you can do, the voltage is going to dip.

Use a good 2ga or larger cable and you'll be fine.

Correct, you'll want to be sure the ground connection is solid or that will cause more voltage drop.
