is this the style that will keep them separated with the car on as well?That is about as good as you will find. The largest I could find in the diode based units was around 200A, like this one. What I did learn is that you can parallel them just like batteries if you need more than 200A of throughput.
Just an FYI though, you will see a small drop in voltage using this style of isolator, so the MLA adapter or an external regulator would be helpful to offset the voltage loss.
