I found a picture of a high amperage buck driver Lexel made and its using the same 3.3uH inductor. What driver do I need to run an XHP70 or 70.2? - #7 by Lexel
So maybe he uses the 100uH for the lower amperage drivers? (Correct)
The sense resistor bank is very similar between those two drivers with 0.025 and 0.035. So I don’t think thats a good indicator of which is which.
That’s all i can find. Nothing conclusive.
