I didn't do a saturation test on the Aurora choke, didn't see the need for it as Poida and others tested and posted results of many chokes (not one of these that I am aware of) these were a little bit bigger cross section than the aerosharp cores and results should be marginally better.
I still have one Complete 5Kw Aurora choke and will check it with the LCR tester (if it still works)when I get time tonight or in a few days orso, I need to build another charge controller anyway.
Edit:
Ok found something I was looking for, The lab power supply I have is only 30v not relevant but it has a USB power supply to run the LCR meter to test the choke.
I have photo's but you will likely do your own later so here are the numbers, The choke as is tested 517uH, now with the loop at the bottom cut One coil measures 157uH then join the 2 in parallel (as in the photo take not of which winding's are the inner layer and outer layer) I get 145.9uH
You may wind your own but this is an easy start for a first build IMO.

I used a LC200A tester, old version without the case.
