speaking of capacitors, I don't see any in your picture... are they just hidden in the picture?

My capacitors are the same as originall coguar in the picture top left green and black tape conected by wieres with B- and B+ with power board.
Coul you tell me more about snubber, like an RC snubber what parametrs I could try?
My problem
at the moment is that controler works with 100A battery limits when I have incresed current to 200A mosfets blown up and get short circuit
I gave the same time production line mosfets but :
- maybe I need compare the gates capacitance more carefully acording to time of open mybe I can build special tool to check speeds of mosfets?
-or maybe it is something wrong with control board or software parametrs ???
