I started using a Battery Tender now that it is below 0 at night.
Was not sure how it would work with the True Isolator.
This what I found.

After using the Battery Tender over night, both batteries were at 12.8v.
After starting the main battery is at 14.7v and the aux is at 14.5v.
The Battery Tender is connected to the same place the main battery is connected to on the True Isolator.

Hope this helps anyone with the same question I had.
