Hi Westic

If you look at the Anderson website

The 175amp plug is actually good for up to 280 amps but is only able to be safely disconnected with 100 amps running through it. It is also able to take 1/0 cable or 50mm flexible cable if you use metric.

Using the enerdrive installation chart, (this information is taken from Blue Seas a very reputable company)

Using the maximum 3% volt drop sizing part of the chart (0.42volts on a 14volt system, the charging voltage. Less if calculated at 12v)

1/0 Awg cable or 50mm on a circuit 4.5m to 6 meters long can safely carry 150amps.

1awg can carry 120amps and 3/0 Awg can carry 200amps

While the chart doesn’t specifically mention 1/0 Awg below this length of your follow the diagonal line across using the other sizes and lengths of circuits, it’s pretty easy to draw the conclusion that 1/0 cable can easily carry in excess of 200 amps in a circuit under 2 meters in total length.

These tables are based on continuous use, not short term loads, where they can easily carry 50% more load as a safety factor.

If you use the 10% volt drop chart (maximum 1.4v) you could safely use 1/0 Awg to run 150amps for a circuit 15-19 meters long. I wouldn’t, but you can.

They key thought is to ensure you have 200 amp continuous draw, so get at least 2 x 100A/h lithium batteries.
