They probably got rid of the reverse polarity protection FET and dual sense resistors for space saving, having to use physical RPP (only button) and higher minimum.

Again it’s based on the MP3429, 12V output for this version, I believe the XHP70.2 version is 6V.
What is interesting is that they use a second higher value (0.25Ω, 2x 0.5Ω weirdly) sense resistor for the moonlight mode, like my drivers and Zebralight’s (usually they use 3). The low value high power sense resistor is 10mΩ + the ON resistance (3mΩ) of the NFET (AON7520) used to switch between the two.
The turbo output starts to decrease below 3.5V and reach ”h…
