Are these ratings approved by, and published publicly, by the manufacturers?

The Hobbywing (Maker of the Speed Passion) uses the FET that is rated for Ta 32A and it has a total of 24 FETs, 8 per phase, but in a H bridge only 4 should be added which gives it a 128A rating. The LRP uses the same FET as the Tekin R1/RS and the same amount so they're rated the same. The Xcelorin uses a total of 18 FETs like the GTB/Kinetik, but it's the same as the Hobbywing (IRF6635), so 3 time 32A is 96A and like the Novak all the FETs are cooled by the heat sink which should help raise the rating a bit. CRC (Advanced Electronics) is somewhat unknown and I've contacted them to get one, but no answer yet. The others like Ko Propo, Futaba, Keyency and GM, we would need to know how many FETs and the part number as I haven't seen any inside pictures of them.
