Can't find mosfet info

[medusa569]

Hello all. I need help identifying these parts. I search for the sheets in these and find nothing. They were taken off of a bicycle battery management system..for a 36 volt battery pack. Any help would be appreciated !

2 MOSFETS T430 BN9C77 (2) BN9C2F (1)

Are you sure the others are transistors?
